Product Overview
XL-IRM1838C is a XINGLIGHT 38 kHz infrared receiver module classified in the LED category and identified as a sensor. Its optical receiver structure combines a high-speed, high-sensitivity PIN photodiode with a low-power, high-gain preamplifier IC. The output interface is TTL and CMOS compatible with active-low logic, supporting direct connection to logic input stages within the stated electrical limits.
The device is supplied in an epoxy resin semi-circular spherical plastic package with a 6.5 x 5.4 x 4.1 mm body and 23.8 mm lead length. Unless otherwise specified, dimensional tolerance is ±0.25 mm. Assembly limits include wave soldering at 260°C for no more than 6 seconds and manual soldering at 300°C for 3 seconds.
Electrical operation is centered on a 37.9 kHz typical input carrier frequency with a 6 kHz typical band-pass filter width. Recommended supply voltage is 2.7 to 5.5 V, while the absolute maximum supply rating is 6.0 V at 25°C. The module is intended for infrared receiver designs requiring defined receive distance, active-low logic output, and dual shielding anti-interference construction.
