The Würth Elektronik 151051RS11000 is a 5 mm through-hole red indicator LED from the WL-TMRC series, designed for reliable visual indication in electronic circuits and PCB assemblies. It features a diffused round lens and produces red light with a dominant wavelength around 645 nm, making it suitable for clear status indication in control panels, instrumentation, and consumer electronics.

This LED uses a standard T-1 3/4 (5 mm) package with two through-hole leads, enabling easy mounting on printed circuit boards. With a forward voltage around 2.1–2.5 V and a viewing angle of approximately 60°, it provides efficient illumination while maintaining low power consumption.

The device is designed for high reliability and long operating life, with standard 2.54 mm lead spacing and built-in stand-offs that simplify PCB assembly and ensure consistent mounting height.
