IR 远程控制接收器，通孔封装，Vishay SemiconductorVishay IR 接收器用于远程控制和红外通信应用、红外代码学习/转发器、红外光挡板和红外接近传感器。 红外接收器在 840 nm 到 960 nm 的波长范围内工作。高灵敏度，长传输范围 30KHz 至 56KHz 的载波频率 ### IR 远程控制接收器，Vishay Semiconductor

The is a 38kHz Miniaturized IR Receiver Module for infrared remote control systems. A PIN diode and a preamplifier are assembled on lead frame. The demodulated output signal can be directly connected to a microprocessor for decoding. This IR receiver module is optimized to suppress almost all spurious pulses from energy saving lamps like CFLs.
