SPMWHT541MP5WKU0S5

Overview

The SPMWHT541MP5WKU0S5 is a white LED from the LM561B Plus series by Samsung Semiconductor, Inc. It features a natural white color with a correlated color temperature of 3500K and a Color Rendering Index (CRI) of 80. The component operates at a forward voltage of 2.95V and a test current of 65mA, delivering a luminous flux of 35 lumens at 25°C. It offers an efficacy of 182 lm/W with a viewing angle of 120°. Packaged in a 4-SMD flat lead (5630) format measuring 5.00mm x 3.00mm x 0.80mm, it has a maximum rated current of 180mA and a thermal resistance of 15°C/W.

Feature Summary

• High luminous efficacy of 182 lm/W for energy-efficient illumination
• Wide 120-degree viewing angle for broad light distribution
• Compact 5630 surface-mount package design

Applications

• General indoor lighting fixtures
• Commercial area lighting applications
• Residential ambient lighting systems

Procurement Notes

Verify the specific suffix 'KU' against official Samsung documentation to confirm the 3500K color temperature specification, as ordering codes define exact optical parameters. Confirm availability status, as related models in this series may have different lifecycle statuses. Ensure compatibility with existing thermal management solutions given the 15°C/W thermal resistance rating.

Selection Notes

Select this component when a neutral-to-warm white appearance (3500K) is required alongside high efficiency. The 120-degree beam angle suits applications needing wide dispersion without additional optics. Compare against other LM561B Plus variants if a different color temperature or packaging configuration is needed for the target design.

Part Context

This part belongs to the LM561B Plus series, designed for general lighting applications. Samsung Semiconductor utilizes advanced phosphor technology in this series to achieve high CRI and consistent color rendering. The 5630 form factor is standard for modern surface-mount LED arrays used in various solid-state lighting products.
