3SRD-F

LED Indication - Discrete Overview

The Bivar Inc. 3SRD-F is a single-color red LED in a T-1 (3mm) through-hole package with a diffused lens. It operates at a peak wavelength of 655 nm and delivers a luminous intensity of 40 mcd. The component features a radial configuration with a forward voltage of 1.7V and a maximum operating temperature of +85°C. Designed for discrete indication, it utilizes a standard circular dome lens style suitable for general-purpose electronic signaling applications.

LED Indication - Discrete Feature Summary

• Through-hole mounting in a compact T-1 3mm radial package
• Diffused lens design for wide-angle light distribution
• Super bright red emission optimized for visibility

LED Indication - Discrete Applications

• General purpose electronic status indication
• Power supply activity signaling
• Control panel indicator lights

LED Indication - Discrete Procurement Notes

Verify the specific datasheet revision to confirm electrical tolerances and mechanical dimensions prior to integration. Ensure that the selected supplier provides components compliant with RoHS standards as specified by the manufacturer. Cross-reference the part number against official Bivar catalogs to distinguish between standard and super-bright variants within the same series.

LED Indication - Discrete Selection Notes

Select this component when a high-visibility red indicator is required for through-hole PCB assembly. The diffused lens offers superior viewing angles compared to clear lenses, making it suitable for applications where the LED may not be directly visible from all positions. Consider the 1.7V forward voltage drop for circuit current limiting resistor calculations.

LED Indication - Discrete Part Context

This component belongs to Bivar's line of discrete LEDs designed for panel mounting and board-level indication. The T-1 form factor is a standard industry size for low-profile applications. The 3SRD-F variant specifically targets high-intensity requirements within the red spectrum, differentiating it from lower-output models in the same physical package family.

LED Indication - Discrete Replacement Considerations

The 3SRD-S is listed as a similar alternative from the same manufacturer. Verify compatibility regarding luminous intensity and forward voltage before substitution. Other potential replacements should match the T-1 package, red wavelength, and through-hole configuration.
