BL-BKC2V4V-AT

Overview

The BL-BKC2V4V-AT is a yellow discrete LED indicator manufactured by American Bright Optoelectronics Corporation. It features a 5mm round lamp head with a domed top lens and radial leads. The component operates at a typical forward voltage of 2V with a test current of 20mA. It delivers an illumination intensity of 800 millicandela. The device supports an operating temperature range from -40°C to +85°C and includes a reverse voltage rating of 4V.

Feature Summary

• Yellow illumination color for clear visual indication
• Radial lead configuration for through-hole mounting
• Domed top lens style for optimized light distribution

Applications

• General purpose panel indicators
• Power status signaling in electronic devices
• Control board activity monitoring

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to ensure correct binning and electrical characteristics. Confirm RoHS compliance status if required for assembly processes. Check lifecycle status as components may be discontinued or subject to last-time-buy restrictions. Validate package dimensions against PCB footprint requirements prior to procurement.

Selection Notes

Select this component when a standard 5mm yellow indicator is required for through-hole applications. Ensure the circuit design accommodates the 2V forward voltage drop at 20mA. Consider the 800mcd brightness level for visibility requirements. Verify that the operating temperature range meets the environmental conditions of the final application.

Part Context

This part belongs to the BL series of discrete LEDs from American Bright Optoelectronics Corporation. It is designed for general indication purposes rather than high-power lighting. The radial lead format distinguishes it from surface-mount alternatives within the same product family.

Replacement Considerations

Cross-reference with similar 5mm yellow radial LEDs from other manufacturers. Ensure compatible forward voltage and current ratings are maintained. Verify mechanical compatibility of the lead spacing and lens diameter for direct replacement.
