The MIM-0KM2ASF SERIES is miniaturized infrared receivers for remote control and other appplications requiring improved ambient light rejection. The separate PIN diode and preamplifier IC are assembled on a single leadframe. The epoxy package contains a special IR filter. This module has excellent performance even in disturbed ambient light applications and provides protection against uncontrolled output pulses.
The MIM-OKM2ASF series is a miniaturized infrared receiver module designed for remote‑control and other applications that require strong ambient‑light rejection. It integrates a PIN photodiode, pre‑amplifier IC, and an internal IR filter in a single lead‑frame package, offering high immunity to ambient light and electric‑field disturbances.
