156125RS75000

Overview

The Würth Elektronik 156125RS75000 is a single-color red surface-mount LED from the WL-SMRW series. It features a 1205 (3212 metric) package with dimensions of 3.2 mm length, 1.2 mm width, and 1.1 mm height. The component emits red light at a peak wavelength of 632 nm and a main wavelength of 624 nm. Key electrical parameters include a forward voltage of 2 V at a test current of 20 mA, with a power rating of 48 mW. The optical intensity is 110 mcd, and it offers a viewing angle of 140 degrees. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Utilizes a rectangular water-clear lens for effective light transmission in a compact SMD form factor.
• Designed for bottom entry surface mount installation to facilitate automated PCB assembly processes.
• Provides wide-angle illumination characteristics suitable for general indicator applications.

Applications

• Status indication on electronic circuit boards
• Panel status indicators for consumer devices
• General-purpose visual signaling in industrial equipment

Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official Wurth Elektronik documentation to ensure correct wavelength and binning specifications. Confirm moisture sensitivity level (MSL 3) handling requirements during storage and soldering. Cross-reference datasheet revisions to validate RoHS compliance status and packaging details prior to procurement.

Selection Notes

Select this component when a low-profile red indicator is required for space-constrained designs. Ensure the driving circuit accommodates the 2 V forward voltage drop at 20 mA. Consider the 140-degree viewing angle for visibility requirements. Verify thermal management capabilities given the 48 mW power rating and operating temperature limits.

Part Context

This component belongs to the WL-SMRW series of single-color LEDs manufactured by Würth Elektronik. The series includes various colors and intensities within the 1205 package format. It is distinct from other Würth LED families such as WL-SMTW or WL-SBRW which may differ in lens shape, mounting style, or electrical characteristics.
