156125BS57000

Overview

The 156125BS57000 is a single-color surface-mount LED from the Würth Elektronik WL-SMRD series. It emits blue light with a peak wavelength of 470 nm and a luminous intensity of 80 mcd. The component features a rectangular lens with dimensions of 3.20 mm in length, 1.20 mm in width, and a maximum height of 1.20 mm. It operates at a typical forward voltage of 2 V and a test current of 20 mA. The device utilizes a water-clear lens and supports bottom-entry surface mount installation.

Feature Summary

• Blue emission with 470 nm peak wavelength
• Water-clear rectangular lens design
• Bottom-entry surface mount configuration

Applications

• Electronic status indicators
• Panel illumination
• General-purpose signaling devices

Procurement Notes

Verify the specific datasheet for the 156125BS57000 to confirm moisture sensitivity level (MSL) and reflow soldering temperature profiles prior to assembly. Ensure that the ordering suffix matches the required packaging format, such as cut tape or reel, as specified by the manufacturer's documentation. Cross-reference the official part number against authorized distributor catalogs to validate authenticity and technical compliance before finalizing procurement orders.

Selection Notes

Select this component when a compact blue indicator with a 1205 footprint is required. The 80 mcd intensity suits applications needing moderate visibility without excessive power consumption. Consider the 2 V forward voltage drop for circuit design compatibility. Verify that the bottom-entry mounting style aligns with the target PCB layout constraints and thermal management requirements.
