57-21/GHC-AT1U2M/BF

Overview

The 57-21/GHC-AT1U2M/BF is a green surface-mount LED from Everlight Electronics. It features a boomerang package design with side-view optics. The component emits light at a peak wavelength of 527nm. Forward voltage is specified at 3.35V, and the luminous intensity reaches 500mcd at a forward current of 25mA. It utilizes AlGaInP material technology for efficient emission.

Feature Summary

• Boomerang-shaped SMD package design
• Side-view optical configuration
• RoHS compliant construction

Applications

• Indicator lighting in consumer electronics
• Status indication on circuit boards
• Backlighting applications requiring side visibility

Procurement Notes

Verify the specific suffix BF against the official Everlight datasheet to confirm lens color and binning specifications. Ensure compatibility with standard reflow soldering profiles. Confirm that the side-view orientation meets the mechanical constraints of the target PCB layout before finalizing procurement orders.

Selection Notes

Select this component when a low-profile, side-emitting indicator is required. The boomerang form factor allows for compact board layouts. Consider the 3.35V forward voltage drop for power supply calculations. Verify that the 500mcd intensity satisfies visibility requirements for the intended application environment.

Part Context

This part belongs to the 57-21 series of surface-mount LEDs. The series offers various optical angles and package styles. The boomerang variant provides distinct mounting characteristics compared to standard rectangular SMD LEDs. It is designed for automated placement processes in high-volume manufacturing environments.

Replacement Considerations

Direct substitutes require matching the 0603-like footprint, side-view orientation, and green wavelength. Check alternative manufacturers for similar boomerang packages. Verify electrical parameters such as forward voltage and luminous intensity to ensure functional equivalence in the existing circuit design.
