Product Overview
The XL-IRM1738 is a XINGLIGHT infrared remote receiver module listed under the LED category. Its package is an epoxy resin plastic encapsulated semi-circular spherical nose bridge body measuring 6.7 x 5.3 x 4.5 mm, with 22 mm lead length and a general dimension tolerance of ±0.25 mm unless otherwise specified.
Electrical operation is defined around a recommended 2.7 to 5.5 V supply range and a 37.9 kHz typical input carrier frequency. At VDD=5 V and Ta=25°C, working current is specified at 0.3 mA minimum, 0.4 mA typical, and 0.5 mA maximum. Output is TTL and CMOS compatible with active-low logic, including a low-level output voltage of 250 mV maximum at Isink=2.0 mA and a high-level output range of 4.5 to 5.0 V at VCC=5 V.
The receiver supports 6 m minimum and 8 m typical receive distance at 0 degrees, with 5 m minimum and 6 m typical at left or right 35 degrees. Assembly limits include 240°C wave soldering for up to 6 seconds and 300°C manual soldering for 3 seconds.

Procurement Notes
When requesting a quote for XL-IRM1738, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For LED and optoelectronic sourcing, brightness bin, wavelength or color temperature bin, forward voltage range, viewing angle, moisture sensitivity level and soldering process limits may affect final selection, availability and lead time.
