CLM3A-BKW-CTBUB453

Overview

The CLM3A-BKW-CTBUB453 is a single-color blue LED from the Cree LED family, designed for surface-mount applications. It features a rectangular lens with non-diffused transparency and emits light at a dominant wavelength of 470 nm. The component operates within a temperature range of -40°C to +100°C and has a maximum forward current rating of 20 mA. Key electrical parameters include a forward voltage of 3.1 V and a power rating of 100 mW. The package dimensions are 2.7 mm in length, 2 mm in width, and 1.3 mm in height.

Feature Summary

• Surface-mount design suitable for automated assembly processes
• Rectangular colorless lens providing non-diffused light output
• High reliability performance under wide environmental conditions

Applications

• LED indication circuits
• Discrete LED lighting components

Procurement Notes

Verify component availability status as listings indicate potential discontinuation at certain distributors. Confirm specific binning requirements for luminous intensity if precise brightness levels are critical for the application. Ensure compliance with moisture sensitivity level handling procedures during storage and reflow soldering processes.

Selection Notes

Select this component when a standard PLCC-2 footprint is required for blue illumination. Consider the 120-degree viewing angle and 470 nm wavelength for visibility needs. Evaluate thermal management capabilities given the 100 mW power rating and ensure the PCB layout supports the specified 20 mA forward current without exceeding junction temperature limits.
