INFRARED RECEIVER MODULE
Description
INFRARED RECEIVER MODULE
Description
The MIM-0KM4AKL 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.
