ADXL345BCCZ is a digital three-axis accelerometer from Analog Devices in a 14-pin LGA package — for motion detection, tilt sensing, tap/double-tap input and free-fall detection in handheld, wearable and industrial devices. Its advantage is the built-in activity/inactivity and tap sensing: motion events wake the host from sleep without continuous polling, which cuts system power in battery designs. Rev. G lists exactly one package for this device — the 14-lead LGA — and the plain BCCZ code is the tray version, so the package is fixed and only the supply form varies with the suffix. For new designs, compare against current-generation accelerometers on power and noise if your budget allows; for existing designs, match the code exactly.

BME280 is a digital humidity, pressure and temperature sensor from Bosch Sensortec in an LGA-8 package — for weather stations, indoor navigation and IoT environmental monitoring. Three sensors in one 2.5 mm package is the selection point: humidity, pressure and temperature from a single I2C device, which is why it became the default environmental sensor for maker and IoT designs. Selection advice: for humidity plus temperature only, the BME280 also covers pressure you may not need — confirm whether your application needs barometric pressure before choosing between this and humidity-only alternatives. Verified operating envelope (Bosch BST-BME280-DS001): 300–1100 hPa pressure, 0–100 %RH humidity and −40 °C to +85 °C, humidity accuracy ±3 %RH, pressure RMS noise 0.2 Pa; supply 1.71–3.6 V with a separate 1.2–3.6 V interface rail, 0.1 µA sleep current, and the I2C address is 0x76 or 0x77 depending on the SDO pin. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

BMP280 is a digital barometric pressure and temperature sensor from Bosch Sensortec in an 8-pin metal-lid LGA (2.0 × 2.5 × 0.95 mm), for altitude estimation, weather monitoring, drones and indoor navigation. Order with the manufacturer's sales part number and ordering code — for example 0 273 300 436 / 0.273.300.436-1NV (BST-BMP280-DS001 Rev 1.26, October 2021, p1) — and confirm packaging and quantities at quotation. Its advantage is the combination of small size, low power and factory-calibrated digital output — pressure and temperature arrive over a digital bus with no analog signal chain to design. Selection advice: Bosch ships the BMP280 in a compact LGA that demands proper reflow profiling; confirm your assembly process handles LGA packages. For new designs, also check whether the BME280 (adds humidity) or BMP388 (newer generation) better fits your requirements — but they are not drop-in code-compatible, so the sensor choice must be fixed before firmware is finalized. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ICM-42688-P is a low-noise 6-axis gyroscope and accelerometer from TDK InvenSense in an LGA-14 package — for drones, robotics, wearables and image stabilization. Its verified figures are the selection point: gyroscope noise of 2.8 mdps/√Hz and accelerometer noise of 70 µg/√Hz, full-scale ranges of ±15.6 to ±2000 dps and ±2 g to ±16 g, output data rates up to 32 kHz with a 2 KB FIFO, at 0.88 mA in 6-axis low-noise mode (typical). The on-chip APEX engine handles motion features — pedometer, tilt, tap and wake-on-motion — but it is not a sensor-fusion co-processor: orientation fusion runs on the host. Selection advice: the P variant is the high-performance member of the family — confirm full-scale range and ODR against your motion profile, and pick the interface deliberately: I3C at 12.5 MHz, I2C at 1 MHz or SPI at 24 MHz, on a 1.71 V to 3.6 V supply across −40 °C to +85 °C. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

LIS3DHTR is an ultra-low-power digital three-axis accelerometer from STMicroelectronics in an LGA-16 package — for motion detection, screen rotation and vibration monitoring in battery-powered devices. The ultra-low-power design with built-in motion-detection interrupts is the selection point: it wakes the host only on real events, which is how wearables and asset trackers stretch battery life. Selection advice: the TR suffix denotes tape and reel — match the full LIS3DHTR code for production orders. ST's product page lists only this LIS3DHTR code, marked Active; the tray form (plain LIS3DH) no longer appears there, so order against the full TR code. Output data rates run from 1 Hz to 5.3 kHz and consumption goes down to 2 µA in ultra-low-power mode per ST's product page; the part carries no ST longevity-program commitment, so confirm your full-scale range (±2/±4/±8/±16 g) and output data rate needs against the datasheet. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SHT31-DIS-B2.5KS is a digital humidity and temperature sensor from Sensirion in a DFN-8 package, with factory-calibrated output — for HVAC, environmental monitoring and consumer appliances. The factory calibration is the selection point: ±2% RH accuracy out of the box with no production calibration step, which removes test time from your line. Selection advice: the B denotes the standard version without a filter membrane (the -F variant adds a PTFE membrane), and the 2.5KS suffix denotes 2,500-piece tape-and-reel packing — match the full SHT31-DIS-B2.5KS code. For tighter accuracy, step up within the SHT3x family; for cost-driven designs, the SHT30 is the drop-in alternative. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

OPT3001DNPR is a digital ambient light sensor from Texas Instruments in a USON-6 package, with human-eye spectral response — for display backlight control, lighting systems and optical switching. The human-eye-matched spectral response is the selection point: it measures what people actually perceive, so display dimming tracks real viewing conditions instead of raw lux. Selection advice: the DNPR suffix denotes USON-6 on tape and reel — match the full OPT3001DNPR code to your footprint. Confirm your lux range and interrupt needs against the datasheet. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TMP117AIDRVR is a high-accuracy digital temperature sensor from Texas Instruments in a 6-pin WSON package, with an I2C interface — for precision thermal monitoring in medical, industrial and test equipment. High accuracy without calibration is the selection point: where an NTC thermistor needs per-unit calibration, the TMP117 delivers calibrated digital readings out of the box, removing a production step. Selection advice: the DRVR suffix denotes the WSON-6 package on tape and reel — match the full code to your layout. Confirm your accuracy requirement against the datasheet before paying for precision you do not need; for coarse monitoring a cheaper sensor suffices. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

Analog Devices lists DS18B20+ as a PRODUCTION programmable-resolution 1-Wire digital thermometer, -55 to +125 °C range, ±0.5 °C accuracy (-10 to +85 °C), 9 to 12-bit resolution. The 1-Wire interface is the procurement advantage: dozens of sensors share a single data line with unique 64-bit IDs, which slashes wiring cost in multi-point temperature monitoring. Selection advice: the + denotes the lead-free configuration in the TO-92-3 through-hole package — the DS18B20 also ships in SO and other SMD packages, so match the full DS18B20+ code to your assembly process. Each device carries a factory-programmed unique ID, which your firmware uses for bus addressing; confirm your resolution setting (9–12 bit trades speed for precision) during design. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ACS712ELCTR-05B-T is an Allegro MicroSystems fully integrated Hall-effect linear current sensor IC in SOIC-8 (LC package), supplied on tape and reel — for bidirectional AC and DC current sensing in motor control, load detection and management, switched-mode power supplies and overcurrent fault protection. The sensed current flows through an internal copper conductor, so the measurement is isolated from the signal pins by the package insulation system. The isolation rating is given in the current data sheet (ACS712-DS Rev. 22) and in the parameter table. Selection advice: the -05B code is the ±5 A sensing range — the smallest of the family — and sets the sensitivity — the -20A and -30A siblings are different ranges, not equivalents; the bandwidth is set via the FILTER pin, and the conditioned sensitivity, error and isolation rows are in the parameter table. Parameters verified against Allegro MicroSystems documentation (ACS712-DS Rev. 22). State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

Selection advice: the 2.5KS suffix denotes the accuracy grade and reel packing — match the full SHT30-DIS-B2.5KS code. For tighter accuracy, the SHT31 is the drop-in upgrade in the same footprint. Confirm your RH accuracy needs against the datasheet before choosing. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SGP40-D-R4 is a digital VOC gas sensor from Sensirion in a DFN-6 package — for indoor air quality monitoring in HVAC, purifiers and smart buildings. The MOX-based VOC sensing with on-chip compensation is the selection point: it turns raw gas resistance into a calibrated air-quality signal without external processing. Selection advice: the D-R4 suffix denotes the DFN package on tape and reel — match the full SGP40-D-R4 code. Note this senses VOCs, not CO2 — for CO2 monitoring, pair it with or choose the SCD4x NDIR sensor instead. Confirm your air-quality metric needs against the datasheet. Parameters verified against the Sensirion official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SCD41-D-R1 is an NDIR CO2 sensor from Sensirion in an LGA-20 package, with digital I2C output — for demand-controlled ventilation, indoor air quality and IoT sensing. The true NDIR CO2 measurement is the selection point: it measures CO2 directly by infrared absorption, unlike VOC-based estimates, which is what building codes and ventilation standards require. Selection advice: the D-R1 suffix denotes the LGA package on tape and reel — match the full SCD41-D-R1 code. For cost-driven designs that can accept VOC-estimated CO2, the SGP40 is the cheaper alternative; for real CO2 numbers, stay with NDIR. Parameters verified against the Sensirion official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SHT40-AD1B-R2 is a high-accuracy digital humidity and temperature sensor from Sensirion in a DFN-4 package — the fourth-generation SHT sensor for HVAC, medical and high-reliability environmental monitoring. The smaller DFN-4 footprint with improved accuracy over the SHT3x is the selection point: the upgrade path for designs that need better RH accuracy in less board space. Accuracy grades: SHT40 base is ±1.8 %RH typ; for tighter specs step up to SHT41 (intermediate) or SHT45 (±1.0 %RH typ, ±0.1 °C). Note AD1P is the removable-protection-cap package option, not a higher accuracy grade — AD1B and AD1P share the same base accuracy. I2C address: 0x44 for the A-variant (SHT40-AD1B); the 0x45 address is the B-variant (SHT40-BD1B-R2) — AD1B vs AD1P does not change the address; confirm against your bus layout. Migration note: SHT40 is NOT pin-compatible with SHT3x (DFN-4 vs DFN-8) — board redesign required, do not assume drop-in replacement. Selection advice: the AD1B-R2 suffix decodes as A = I2C address 0x44, B = standard package without membrane (F = polyimide membrane, P = protection cap), R2 = tape & reel 2,500 pcs — match the full SHT40-AD1B-R2 code. For cost-driven designs, the SHT30 remains the budget pick in a larger package. Parameters verified against the Sensirion official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

The 50 A range in a standard SOIC-16 is the selection point: high-current isolated sensing without a bulky module or external shunt. Selection advice: the 050B5 code denotes the 50 A bidirectional variant — the ACS37002 ships in multiple ranges that are not interchangeable, so match the full ACS37002LMABTR-050B5 code. Confirm your current range, bandwidth and isolation requirements against the datasheet. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
