C543A-WMN-CCCKK141

Overview

The C543A-WMN-CCCKK141 is a 5mm round through-hole LED from Cree LED, emitting cool white light. It features a T-1 3/4 bulb size with a domed top lens and a 20-degree viewing angle. Typical forward voltage is 3.2V at a test current of 20mA. Luminous intensity ranges from 15000 to 22000 mcd (15 to 22 cd). The component is supplied in bulk packaging.

Feature Summary

• Emits cool white light with high luminous intensity
• Features a 5mm round domed lens for superior light output
• Designed for standard through-hole mounting applications

Applications

• Indicator lights
• General illumination
• Status indication

Procurement Notes

Verify the specific ordering suffix CCCKK141 against the official datasheet to ensure correct binning and optical characteristics. Confirm that the bulk packaging format aligns with assembly requirements. Check lifecycle status as some sources indicate obsolete status while others list active. Ensure compatibility with existing PCB footprints for T-1 3/4 packages.

Selection Notes

Select this component when a bright cool white indicator is required in a 5mm through-hole form factor. The 20-degree beam angle provides focused illumination suitable for direct visibility. Consider the typical 3.2V forward voltage drop for circuit design. Verify availability as supply status may vary between active and obsolete classifications across different distributors.
