Overview
The Würth Elektronik 150141YB73100 is a blue and yellow bi-color surface-mount LED in the WL-SBTW series. It features a 3528 (4-PLCC) package with a water-clear lens. The blue element emits at 465nm peak wavelength with a typical forward voltage of 3.2V, while the yellow element operates at 592nm peak with a typical forward voltage of 2V. Both elements are tested at 20mA. The device provides a viewing angle of 120 degrees and has a maximum height of 2.10mm.
Feature Summary
- Bi-color configuration combining blue and yellow light sources within a single compact SMD package
- Water-clear lens design optimized for top-view illumination applications
- Standardized 3528 footprint facilitating integration into space-constrained circuit boards
Applications
- Flat backlighting for LCD displays
- General electronic equipment status indication
- Industrial equipment signaling
Procurement Notes
Verify the specific ordering suffix to confirm the exact binning parameters for luminous intensity and chromaticity coordinates required by your design. Ensure that the procurement documentation references the official Würth Elektronik datasheet for the WL-SBTW series to validate RoHS compliance and material declarations prior to finalizing purchase orders.
Selection Notes
Select this component when a dual-color indicator is needed in a standard 3528 form factor. Consider the distinct forward voltage requirements for each color channel during driver circuit design. Verify that the 120-degree viewing angle meets the visibility requirements of the end product enclosure.
Part Context
This part belongs to the WL-SBTW series of bi-color LEDs from Würth Elektronik. It shares the physical dimensions and mounting style with other components in the 150141 family but differs in internal chip composition and optical output characteristics due to its dual-emitter structure.
Replacement Considerations
Direct substitutes include other 3528 bi-color LEDs from Würth Elektronik such as the 150141YS73100 or 150141YR73100, provided the specific color wavelengths and intensity bins match the application requirements.
