Product Overview
The XL-IRM1838B is a XINGLIGHT 38 kHz infrared receiver module in the LED category. Its structure is an epoxy resin plastic semi-circular spherical nose bridge package, with a 7.6 x 5.1 x 3.5 mm body and 22.0 mm lead length. Unless otherwise specified, dimensional tolerance is ±0.25 mm.
Electrical operation is centered on infrared carrier reception near 37.9 kHz, with a typical BPF width of 6 kHz. Recommended supply voltage is 2.7 V to 5.5 V, and the recommended operating temperature range is -20°C to +85°C. Output signaling is TTL/CMOS level and active low, with low-level output voltage specified to 250 mV maximum and high-level output voltage from 4.5 V minimum to 5.0 V maximum at VCC=5 V.
Reception data includes 10 m minimum and 15 m typical receive distance at 0°, and 5 m minimum, 6 m typical at both left 35° and right 35°. Assembly limits include wave soldering at 240°C for no more than 6 s and manual welding at 300°C for 3 s.

Procurement Notes
When requesting a quote for XL-IRM1838B, 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.
