RPM871-H12 is an infrared communication module that supports IrDA Ver.1.2 low power protocol. The module integrates infrared LED, PIN photodiode, LSI, etc., and has low power consumption and small size.
The RPM871-H12 is a surface‑mount infrared communication module that integrates an infrared LED, a PIN photodiode and the necessary driver/receiver circuitry in a single package. It features a power‑down function and low standby current, making it suitable for mobile devices such as cellular phones, PDAs and digital cameras.
Key specifications include a supply voltage range of 2.6 V to 3.6 V, support for SIR data rates from 2.4 kbps to 115.2 kbps, a standby current of 73 µA, and an LED peak wavelength of 870 nm. The module operates from –20 °C to +85 °C and offers adjustable communication distance via LED load resistance.
