ASMT-UWB1-NX3B2

Overview

The ASMT-UWB1-NX3B2 is a cool white surface-mount LED from the ASMT-UWB1 series, manufactured by Broadcom Limited. It features a PLCC-2 package with dimensions of 3.20mm length and 2.80mm width. The component emits light at a color temperature of 6500K with a viewing angle of 120 degrees. Key electrical parameters include a forward voltage of 3.2V and a test current of 20mA. The optical intensity is rated at 2300mcd, and the maximum height is 2.10mm.

Feature Summary

• Emits cool white light with a 6500K color temperature
• Features a standard PLCC-2 SMD package for compact mounting
• Provides a wide 120-degree viewing angle for broad illumination

Applications

• Indicator lighting in electronic devices
• Backlighting for displays and panels
• General purpose status indication

Procurement Notes

Verify the specific suffix NX3B2 to confirm the 6500K cool white color bin, as other suffixes denote different color temperatures within the same package family. Confirm RoHS3 compliance and MSL level 3 handling requirements during storage and assembly. Ensure the ordering quantity matches the manufacturer's standard packaging multiples to avoid partial reel issues.

Selection Notes

Select this component when a cool white light source is required in a low-profile SMD form factor. Compare the 2300mcd intensity against application brightness needs. Consider the 3.2V forward voltage drop for circuit design compatibility. Verify that the 120-degree beam angle meets the optical distribution requirements of the target enclosure or lens system.

Part Context

This part belongs to the ASMT-UWB1 series of white LEDs, which are designed for high reliability and consistent color performance. The series utilizes InGaN technology to produce various white color temperatures in a standardized PLCC-2 footprint, facilitating easy integration into existing PCB layouts requiring white illumination.

Replacement Considerations

The ASMT-UWB1-NX3H2 is listed as a similar alternative, though it typically denotes a warm white variant (3000K). Verify color temperature specifications carefully before substitution to ensure visual consistency. No direct pin-compatible cool white replacement is explicitly confirmed in the provided data.
