SHT30-DIS-B2.5KS

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 2.5KS suffix denotes the accuracy grade and 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.

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. Selection advice: the AD1B-R2 suffix denotes the accuracy grade, I2C address option and reel packing — 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.

AHT20 is a digital humidity and temperature sensor from ASAIR (Aosong) in a DFN package, with I2C interface — for cost-driven consumer, HVAC and IoT designs. The price point is the selection point: factory-calibrated humidity sensing at a fraction of Swiss-sensor cost, which is why the AHT20 became the default in budget IoT products. Selection advice: for the lowest cost, this is the pick; for tighter accuracy and long-term stability specs, compare against the Sensirion SHT3x family. Confirm your RH accuracy needs and supply voltage against the datasheet.

Si7021-A20-GM is a Silicon Labs digital humidity and temperature sensor — I2C interface, ±3% RH humidity accuracy, ±0.4 °C temperature accuracy, −40 to +85 °C, 6-pin DFN-6. The factory-calibrated digital output is the selection point: humidity plus temperature from one 3×3 mm chip with no calibration step on the production line. Selection advice: lifecycle warning — Silicon Labs lists the Si7021-A20-GM as End of Life (LTB announced); for new designs migrate to the current-generation Si70xx/Si71xx sensor, and for repairs and legacy builds we source remaining LTB stock. The A20-GM code pins the DFN-6 package and grade — match it exactly, since the sensor family spans several packages. Evidence: Silicon Labs data confirms EOL/LTB, I2C, ±3% RH, DFN-6. Match the full Si7021-A20-GM code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

SHT30-ARP-B is an analog-output humidity and temperature sensor from Sensirion in a 2.5 × 2.5 × 0.9 mm DFN package — ±3 %RH and ±0.3 °C typical accuracy on a 2.4–5.5 V supply. The analog ratiometric output is the selection point within the SHT30 family: it feeds a plain ADC channel with no I2C stack, for cost-driven designs that already have analog inputs free. Selection advice: the ARP-B suffix denotes the analog-output variant — do not confuse it with the digital I2C DIS variants, which are not interchangeable. Match the full SHT30-ARP-B code. 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.

Sensirion lists SHT30-DIS-B as Active — a digital humidity and temperature sensor with ±2 %RH accuracy (10–90 %RH), I2C interface, 2.15–5.5 V supply, -40 to +125 °C, DFN-8 2.5 × 2.5 × 0.9 mm package. Factory calibration is the advantage: each sensor ships calibrated with the calibration data on-chip, so humidity readings are accurate without production-line calibration. Selection advice: the DIS-B code denotes the I2C variant in DFN-8 — Sensirion ships analog and I2C variants that are not interchangeable, so match the full SHT30-DIS-B code. For condensing or harsh environments, confirm your protection (membrane/filter) requirements; the bare sensor is for non-condensing use.

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.

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.

Microchip lists MCP9808T-E/MC as In Production — a digital temperature sensor in DFN-8, ±0.5 °C maximum accuracy, I2C/SMBus interface, 12-bit resolution, -40 to +125 °C. The ±0.5 °C accuracy with user-programmable thresholds is the selection point: it doubles as a temperature switch with alert output, for thermal management without host polling. Selection advice: the T-E/MC suffix denotes the extended temperature grade in DFN-8 on tape and reel — match the full MCP9808T-E/MC code to your footprint. Confirm your accuracy requirements against the datasheet; for tighter accuracy, step up to a higher-grade sensor. Parameters verified against the Microchip 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.

ACS37002LMABTR-050B5 is an isolated Hall-effect current sensor from Allegro MicroSystems in a 16-pin SOIC package, with a 50 A measurement range on tape and reel — for high-current motor drives, solar inverters and industrial power. 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.
