ASMT-UWB1-NX312

Overview

The ASMT-UWB1-NX312 is a surface-mount white LED from Broadcom Limited, housed in a compact 2-PLCC package. It emits warm white light with a correlated color temperature ranging from 2700K to 4000K. The component features a typical forward voltage of 3.2V and a test current of 20mA. It delivers an optical intensity of 2300mcd with a wide viewing angle of 120 degrees. Physical dimensions are 3.20mm in length, 2.80mm in width, and a maximum height of 2.10mm.

Feature Summary

• Emits warm white light within a 2700K to 4000K color temperature range
• Features a 120-degree wide viewing angle for broad illumination coverage
• Utilizes a standard SMD PLCC-2 package with flat top lens design
• Includes a built-in reflector to enhance light output intensity

Applications

• Internal signage and display indicators
• Office equipment status lights
• Industrial equipment control panels
• Home appliance interface buttons

Procurement Notes

Verify the specific bin code suffix required for your target color temperature, as the NX312 designation covers a range from 2700K to 4000K. Confirm RoHS3 compliance and MSL level 3 handling requirements during storage. Ensure ordering quantities align with manufacturer standard packaging multiples to avoid partial reel issues.

Selection Notes

Select this component when a warm white indication is needed in space-constrained designs. The 2-PLCC form factor allows for easy integration into existing footprints. Consider the 120-degree beam spread for applications requiring diffuse lighting rather than focused spots. Verify thermal management needs based on the 3.2V forward voltage drop at operating currents.

Part Context

This part belongs to the ASMT-UWB1 series of high-brightness white LEDs. The series is designed for general indication purposes where consistent color and high reliability are critical. The UWB1 platform offers various color temperatures to suit different aesthetic and functional requirements across consumer and industrial electronics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 2-PLCC package, 3.2V forward voltage, and specific warm white CCT range.
