VEML7700-TT

BH1750FVI-TR is a 16-bit digital ambient light sensor IC with I2C serial output, 1–65535 lx measurement range, -40 to +85 °C operation in WSOF-6. The 16-bit direct lux output is the advantage: no ADC scaling or calibration math in firmware — the sensor reports illuminance directly for display backlight control and lighting systems. Note the lifecycle: ROHM no longer lists this part on its website (likely discontinued/NRND); parameters follow ROHM original datasheet No.11046EDT01 as hosted by distributors, and exact units are stocked by major malls. Selection advice: for new designs, qualify a current-production ambient light sensor before committing the BOM; for existing builds, remaining stock is lot-dependent — send quantity and date-code requirements with your RFQ. We reconfirm the offered lot before quotation and reply within 24 hours.

OPT3001 is a Texas Instruments digital ambient light sensor in 2x2mm USON-6 — for display backlight control, lighting systems and human-centric IoT where the light reading must match human perception: 0.01 lux to 83k lux measurement with 23-bit effective dynamic range via automatic gain ranging, precision optical filtering that rejects >99% of IR, and 1.8µA typical operating current. I2C/SMBus interface with autonomous interrupt operation lets the host MCU sleep while the sensor watches for light-level events. Selection advice: the human-eye-matched spectral response is the differentiator over discrete photodiodes — for higher speed and precision, the OPT4001 on this site is the upgrade path; the USON package suits space-constrained designs but needs careful reflow profiling. Confirm the I2C address option against your bus layout. Parameters verified against TI documentation. 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.

OPT4001 is a Texas Instruments high-speed, high-precision digital ambient light sensor — for display backlight control and human-presence lighting where the sensor must see what the human eye sees: precision optical filtering matches the photopic response with strong near-infrared rejection, so readings stay accurate behind dark cover glass. Semi-logarithmic output with automatic full-scale selection covers 312.5 µlux to 83 klux (PicoStar) without host gain management, and 12 conversion times from 600 µs to 800 ms trade speed against resolution. Selection advice: two packages exist — the SOT-5X3 (DTS) with interrupt pin for hardware wake-up, and the smaller PicoStar (YMN) without it; pick DTS when the host needs threshold interrupts, YMN for minimum footprint. This is the upgrade path from the OPT3001 — for new designs prefer the 4001 for its wider dynamic range. Parameters verified against Texas Instruments documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

Vishay TSOP38238 is a 38 kHz infrared receiver module for remote-control systems, integrating a PIN diode, preamplifier and PCM-frequency filter in a 3-pin through-hole epoxy package with built-in IR filter. It runs on 2.5–5.5 V at 350 µA, operates from -25 to +85 °C, and achieves up to 45 m transmission range with AGC2 gain control that suppresses spurious pulses from CFL and energy-saving lamps. Its advantage for procurement is integration: one 3-pin device replaces a discrete photodiode, amplifier and filter stage, and the demodulated output connects directly to a microcontroller for decoding. Selection advice: carrier frequency is the critical match — 38 kHz is the de-facto standard for consumer IR remotes, but some protocols use 36, 40 or 56 kHz, so confirm the transmitter carrier before ordering; the AGC2 variant suits continuous and repeat codes, while burst-only protocols may prefer a different AGC type. The side-view through-hole package suits front-panel mounting, and the 2.5–5.5 V range covers both 3.3 V and 5 V logic without level shifting. Evidence: distributor listings (Newark/Farnell) confirm 38 kHz, 45 m range, AGC2 and -25 to +85 °C operation. Confirm exact suffix, packing and date-code requirements in your RFQ — we 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. 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 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.
