Product Overview
The XL-0401UWC is an ultra-miniature white LED packaged in a 0401 surface-mount format intended for high-density PCB layouts and compact electronic assemblies. According to the datasheet, the device uses a white-emitting chip structure with yellow colloid encapsulation and supports standard EIA tape-and-reel packaging for automated placement systems.
The LED provides luminous intensity bins from 500 mcd to 1300 mcd at IF=20mA, with a typical color temperature around 12000K and a typical viewing angle of 120 degrees. Electrical characteristics include a forward voltage range of 2.6V to 3.3V and reverse current not exceeding 1μA at VR=5V. The component supports maximum continuous forward current of 20mA and peak forward current up to 80mA under specified pulse conditions. Operating temperature range is specified from -40°C to +85°C.
The package structure is designed for SMT production and Pb-free reflow soldering compatibility. Recommended applications include indicator lighting, keypad backlighting, mobile devices, industrial instrumentation, routers, TV boxes, and LED backlight assemblies. The datasheet also includes reliability testing references based on MIL-STD and JIS standards for environmental and endurance evaluation.
