5977731102F

Overview

The Dialight 5977731102F is a bi-color surface mount LED indicator featuring red and yellow emission. It utilizes a 4-pin SMD package with no lead construction, designed for board-level mounting. The component operates at a forward current of 30 mA with a forward voltage of 2.6 V. Peak wavelengths are specified at 630 nm for red and 590 nm for yellow. The lens dimensions measure 2.79 mm in length, 2.39 mm in width, and 0.95 mm in height, providing a viewing angle of 120 degrees.

Feature Summary

• Dual-element bi-color configuration enabling independent red and yellow light emission within a single compact footprint.
• Surface mount design with a four-terminal no-lead package structure optimized for automated PCB assembly processes.
• Wide viewing angle characteristic ensuring high visibility of status indicators across broad angular ranges.

Applications

• Electronic equipment status indication
• Control panel signal monitoring
• Board-level operational state signaling

Procurement Notes

Verify the specific datasheet version to confirm exact wavelength tolerances and thermal resistance values. Ensure that the procurement documentation explicitly states RoHS compliance status as required by regulatory standards. Cross-reference the manufacturer's part number against distributor listings to confirm availability and authenticity before finalizing orders.

Selection Notes

Select this component when space constraints require a dual-color indicator in a small surface mount form factor. Consider the 120-degree viewing angle for applications requiring wide visibility. Verify that the operating temperature range meets the environmental requirements of the intended deployment scenario.
