156125GS75000

Overview

The Würth Elektronik 156125GS75000 is a single-color green surface-mount LED from the WL-SMRW series. It features a rectangular lens with water-clear transparency and emits light at a peak wavelength of 520 nm and a dominant wavelength of 525 nm. The component provides a luminous intensity of 450 mcd when driven at a forward current of 20 mA, with a typical forward voltage of 3.3 V. It operates within a temperature range of -40 °C to +85 °C and has a maximum power rating of 78 mW. The package dimensions are 3.2 mm in length, 1.2 mm in width, and 1.2 mm in height.

Feature Summary

• Emits green light with a peak wavelength of 520 nm and a dominant wavelength of 525 nm.
• Features a rectangular lens shape with water-clear transparency for optical clarity.
• Designed for surface-mount technology (SMD/SMT) installation in compact electronic assemblies.

Applications

• General indicator lighting in electronic devices
• Status indication on control panels
• Visual signaling in consumer electronics

Procurement Notes

Verify the specific part number against official manufacturer documentation to ensure accuracy. Confirm that the required luminous intensity of 450 mcd and the 520 nm peak wavelength align with your design specifications. Check the moisture sensitivity level (MSL 3) requirements for proper storage and handling during assembly. Ensure the 1205 (3212 metric) package dimensions fit the designated footprint on the printed circuit board.

Selection Notes

Select this component when a standard green indicator with moderate brightness is required. The 450 mcd intensity suits applications where high visibility is not the primary constraint but clear status indication is needed. Consider the 3.3 V forward voltage drop for power supply calculations. The rectangular lens shape may influence beam distribution compared to dome-style LEDs. Verify compatibility with automated pick-and-place equipment due to the reel packaging format.

Part Context

This LED belongs to the WL-SMRW series by Würth Elektronik, which offers various single-color options in the 1205 (3212 metric) package. The series includes different colors such as yellow and red, each with distinct electrical characteristics like forward voltage and wavelength. This specific model represents the green variant optimized for general-purpose indication tasks requiring standard brightness levels.
