Description
The TFMM5..0 – series are miniaturized receivers for infrared remote control systems. PIN diode and preamplifier are assembled on PC board, the epoxy package is designed as IR filter. The demodulated output signal can directly be decoded by a microprocessor. The main benefit is the reliable function even in disturbed ambient and the protection against uncontrolled output pulses.
