DHT11

AM2302 is a wired-probe digital temperature and humidity sensor module from Aosong — 0–99.9 %RH (±2 %RH) and -40 to +80 °C (±0.5 °C) on a 3.3–5.5 V supply with single-bus digital output over 3 wires. The wired probe form is the selection point: the sensor sits at the measurement point while the host stays away, for greenhouses, HVAC ducts and weather stations. Selection advice: this is the module/probe version of the DHT22-class sensor — for PCB-mount designs, consider the SMD alternatives instead. Confirm your cable length and accuracy needs against the datasheet. Parameters verified against the Aosong official manual.

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.

ACS712ELCTR-05B-T is an isolated Hall-effect current sensor from Allegro MicroSystems in an 8-pin SOIC package, with a 5 A measurement range — for motor control, power supplies and overcurrent protection. The integrated Hall sensor with 2.1 kV isolation is the selection point: current sensing with galvanic isolation and no shunt resistor, so no power dissipation or high-side measurement headaches. Selection advice: the 05B code denotes the ±5 A range — the ACS712 ships in 5/20/30 A variants with different sensitivities that are not interchangeable, so match the full ACS712ELCTR-05B-T code. Confirm your current range and bandwidth 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.

ACS712ELCTR-20A-T is an Allegro MicroSystems fully integrated Hall-effect linear current sensor in 8-pin SOIC (0.154 in narrow), tape-and-reel packing (TR) — ±20 A sensing range, 100 mV/A output sensitivity, ratiometric voltage output centered at 2.5 V, 5 µs output rise time, 80 kHz typical bandwidth, 4.5–5.5 V single supply, ±1.5% total output error at 25 °C, 1.2 mΩ primary conductor resistance, 2.1 kV RMS isolation between pins 1–4 and 5–8, −40 to +85 °C. The integrated copper conduction path is the selection point: current flows through the package itself, so sensing adds only 1.2 mΩ of series resistance — no external high-power shunt resistor and no isolation optocoupler needed for 2.1 kV RMS separation in motor control, SMPS, load monitoring and overcurrent protection. Selection advice: this is the bidirectional 20 A member — the ±5 A and ±30 A siblings differ in sensitivity and bandwidth, and the 20 A choice trades resolution against range, so match the range to your actual fault-current envelope. Allegro notes the ACS712 is not intended for automotive applications. Evidence: Allegro ACS712 datasheet and distributor listings confirm ±20 A, 100 mV/A, 80 kHz, 2.1 kV RMS, 8-SOIC and tape-and-reel packing. Match the full ACS712ELCTR-20A-T code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ACS712ELCTR-30A-T is an Allegro Hall-effect linear current sensor in 8-SOIC — ±30 A bidirectional sensing, 66 mV/A sensitivity, 5 µs output response time, 80 kHz bandwidth, ±1.5% accuracy, 2.1 kVRMS galvanic isolation between the current path and the output, 1.2 mΩ internal conductor, 5 V single supply, ratiometric analog voltage output, tape-and-reel packing (T), -40 to +85 °C. The zero-insertion-loss sensing is the selection point: no external shunt resistor and no power dissipated in the sense path — the current flows through a 1.2 mΩ copper path while the output voltage is proportional to AC or DC current. Selection advice: this is the ±30 A version — the ACS712 also comes in 5 A and 20 A versions with different sensitivity, so match the full ACS712ELCTR-30A-T code to your current range. The FILTER pin lets you set bandwidth with an external capacitor. Evidence: Allegro ACS712 datasheet and distributor listings confirm ±30 A, 66 mV/A, 5 µs, 8-SOIC and reel packing. Match the full ACS712ELCTR-30A-T code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

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. Selection advice: the CCZ suffix denotes the LGA-14 package on tape and reel — the ADXL345 ships in several packages, so match the full code to your layout. For new designs, compare against current-generation accelerometers on power and noise if your budget allows; for existing designs, match the code exactly. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

ADXL345BCCZ-RL is a 3-axis digital accelerometer from Analog Devices in production status, in a 14-lead LGA package with selectable ±2/±4/±8/±16 g ranges and SPI/I2C digital output on tape and reel — for motion sensing, tilt detection and activity monitoring. The selectable g-range with digital output is the selection point: one part covers both high-sensitivity tilt and high-g shock detection, which is why the ADXL345 became the reference hobbyist accelerometer. Selection advice: the BCCZ-RL suffix denotes the LGA-14 package on tape and reel — match the full ADXL345BCCZ-RL code. Confirm your range and interface against the datasheet. Parameters verified against the Analog Devices 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.

AH3711Q-P-B is a Diodes Incorporated automotive-qualified bipolar Hall-effect latch in a through-hole SIP-3 package, with a south-pole-on / north-pole-off output, a 3 V to 27 V operating range, and typical operate and release points of ±10 Gauss. The ±10 Gauss sensitivity is the selection point: it detects weaker magnetic fields than conventional latches, so designs can use smaller, lower-cost magnets and still keep magnetic margin, which cuts BOM cost and shrinks the sensing assembly in BLDC motor commutation, window powerlifts, sunroofs, tailgate drives, seat-adjustment motors, fans, pumps, and speed measurement. The business gain is automotive-grade robustness without added protection parts: a reverse-blocking diode and Zener clamp on the supply plus an overcurrent-limited open-drain output withstand 40 V load dumps, reverse polarity, and short circuits, while the chopper-stabilized design holds switch points stable across the -40°C to +150°C range with minimal drift from temperature and PCB assembly stress, backed by 8 kV HBM and 1 kV CDM ESD ratings. Evidence: the Diodes AH3711Q datasheet (DS47457 Rev. 1-2, October 2025) defines this P-B code as the SIP-3 (Bulk Pack) automotive variant in bulk packing, 1,000 pieces per pack, with marking code 3711Q, AEC-Q100 qualification, PPAP capability, and manufacture in IATF 16949 certified facilities. Selection advice: choose P-B for through-hole assembly, hand soldering, prototyping, or low-volume builds where no SMT line is available; note that bulk packing means manual insertion rather than reel-fed SMT, so for volume surface-mount production use the SA-7 (SOT23) or W-7 (SC59) tape-and-reel codes instead; this SIP-3 variant takes the south pole on the marked side, like the SOT23 variant, unlike the SC59 variant which takes it on the opposite side; choose the non-Q AH3711 only when automotive change control and PPAP are not required. Featured on Mouser New Products (2026-10-08). Parameters verified against Diodes Incorporated documentation.

AH3711Q-SA-7 is a Diodes Incorporated automotive-qualified bipolar Hall-effect latch in a SOT-23 (Type S) package, with a south-pole-on / north-pole-off output, a 3 V to 27 V operating range, and typical operate and release points of ±10 Gauss. The ±10 Gauss sensitivity is the selection point: it detects weaker magnetic fields than conventional latches, so designs can use smaller, lower-cost magnets and still keep magnetic margin, which cuts BOM cost and shrinks the sensing assembly in BLDC motor commutation, window powerlifts, sunroofs, tailgate drives, seat-adjustment motors, fans, pumps, and speed measurement. The business gain is automotive-grade robustness without added protection parts: a reverse-blocking diode and Zener clamp on the supply plus an overcurrent-limited open-drain output withstand 40 V load dumps, reverse polarity, and short circuits, while the chopper-stabilized design holds switch points stable across the -40°C to +150°C range with minimal drift from temperature and PCB assembly stress, backed by 8 kV HBM and 1 kV CDM ESD ratings. Evidence: the Diodes AH3711Q datasheet (DS47457 Rev. 1-2, October 2025) defines this SA-7 code as the SOT23 (Type S) automotive variant in 7-inch tape and reel, 3,000 pieces per reel, with marking code UPQ, AEC-Q100 qualification, PPAP capability, and manufacture in IATF 16949 certified facilities. Selection advice: choose SA-7 for surface-mount production on the industry-standard SOT-23 footprint; choose W-7 only if the layout is built for the SC59 land pattern, since SOT23 and SC59 footprints are not interchangeable, and note that the SC59 variant takes the south pole on the opposite side while this SOT23 variant takes it on the marked side; choose the SIP-3 P-B code for through-hole or hand assembly; choose the non-Q AH3711 only when automotive change control and PPAP are not required.
