BRM-1020
INFRARED RECEIVER MODULE
● Description
1. The BRM-1020 is miniaturized infrared receivers
for remote control and other applications requiring
improved ambient light rejection.
●Package Dimensions:
2. The separate PIN diode and preamplifier IC are
assembled on a single leadframe.
3. The epoxy package contains a special IR filter.
4. This module has excellent performance even in
disturbed ambient light applications and provides
protection against uncontrolled output pulses.
● Features
1. Photo detector and preamplifier in one package .
2. Internal filter for PCM frequency.
3. High immunity against ambient light.
4. Improved shielding against electric field disturbance.
5. 3.0V or 5.0V supply voltage; low power consumption.
6. TTL and CMOS compatibility.
7. Suitable transmission code:NEC code,RC5 code.
● Applications:
NOTES:
1.All dimensions are in millimeters (inches).
2.Tolerance is ±0.10mm (0.004’’) unless otherwise specified.
3.Specifications are subject to change without notice.
1. It can be used for TVs、VTRs、audio equipment
air conditioners、 car stereo radio、toys、 home
computers and all other equipment requiring remote
control.
