BL-B3141P-AT

Overview

The BL-B3141P-AT is a single-color yellow LED indicator manufactured by American Bright Optoelectronics Corporation. It features a 3mm diameter radial through-hole package with a dome-shaped, diffused lens. The component emits light at a wavelength of 588 nm and provides a luminous intensity of 35 mcd when driven at a forward current of 20 mA. Typical forward voltage is 2.1 V, with a power rating of 80 mW. It operates within a temperature range of -40°C to +85°C and offers a viewing angle of 50 degrees.

Feature Summary

• Yellow emission with 588 nm wavelength for clear visual indication
• Diffused dome lens design providing a 50-degree viewing angle
• Through-hole mounting style suitable for standard PCB layouts
• Durable epoxy construction for reliable performance

Applications

• General purpose status indication in electronic devices
• Power supply unit front panel indicators
• Control panel signal lights
• Consumer appliance status displays

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required lens diffusion and color specifications. Confirm RoHS compliance status directly with the supplier as availability may vary. Check regional distribution channels for stock availability, as some distributors may not carry this specific part number in all locations. Ensure the through-hole footprint matches the target PCB design.

Selection Notes

Select this component for applications requiring a standard 3mm yellow indicator with moderate brightness. The 50-degree viewing angle is suitable for direct line-of-sight visibility. Consider the 2.1V forward voltage drop for circuit design calculations. This part is appropriate for general industrial and consumer electronics where standard through-hole mounting is preferred over surface-mount alternatives.

Part Context

This LED belongs to the American Bright Optoelectronics Corporation single-color LED family. It is designed as a discrete indicator component rather than a lighting source. The product line focuses on durable epoxy lenses and consistent optical output for signaling applications. It serves as a basic visual feedback element in various electronic assemblies.

Replacement Considerations

Cross-reference with other 3mm yellow through-hole LEDs from different manufacturers if supply constraints exist. Verify that substitute parts match the 588 nm wavelength, 35 mcd minimum intensity, and 2.1V forward voltage characteristics. Ensure mechanical dimensions and pin spacing are compatible with existing PCB footprints.
