BL-B3141K-L

Overview

The BL-B3141K-L is a single-color yellow LED from American Bright Optoelectronics Corporation, housed in a T-1 (3 mm) through-hole package. It features a diffused dome lens and emits at a peak wavelength of 585 nm. Key electrical parameters include a forward current of 20 mA, a forward voltage of 2.1 V, and a power rating of 80 mW. The component provides an optical intensity of 45 mcd and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Emits yellow light with a peak wavelength of 585 nm
• Utilizes a diffused dome lens for broad visibility
• Designed for standard through-hole mounting

Applications

• Panel indicator lights
• Status signaling devices
• General purpose illumination

Procurement Notes

Verify the specific suffix against official documentation to confirm exact binning or packaging variations. Confirm RoHS compliance status directly with the manufacturer's datasheet before integration. Ensure the ordering part number matches the required lens transparency and lead configuration for the target PCB design.

Selection Notes

Select this component for applications requiring a standard 3 mm through-hole form factor with high visibility due to its diffused lens. The 20 mA forward current rating aligns with common microcontroller GPIO limits. Consider the 585 nm peak wavelength for optimal human eye sensitivity in yellow indication tasks.

Part Context

This component belongs to the BL-B series of round-type single-color LEDs manufactured by American Bright Optoelectronics Corporation. The series offers various colors and lens types in the T-1 package style, providing reliable performance for industrial and consumer electronic indicator applications.

Replacement Considerations

Cross-reference with other T-1 yellow LEDs such as those from Kingbright or Everlight if supply constraints exist. Verify that substitute parts match the 585 nm wavelength, 20 mA current rating, and physical dimensions to ensure mechanical compatibility.
