3SRD-S

LED Indication - Discrete Overview

The Bivar 3SRD-S is a single-color, surface-mount LED indicator designed for panel applications. It features a 3 mm T-1 (T-18) lens with a diffused red finish to provide uniform light distribution. The component emits red light at a peak wavelength of 645 nm with an intensity of 40 mcd. Electrical characteristics include a forward voltage of 1.7 V and a maximum forward current of 20 mA. It utilizes a through-hole mounting style with straight leads and is supplied in bulk packaging.

LED Indication - Discrete Feature Summary

• Diffused red lens provides uniform light output for clear visibility
• Compact 3 mm T-1 form factor suitable for space-constrained panels
• Through-hole construction ensures secure mechanical attachment

LED Indication - Discrete Applications

• Panel-mounted status indicators
• Equipment power state signaling
• Control board visual alerts

LED Indication - Discrete Procurement Notes

Verify the specific datasheet version for the 3SRD-S to confirm absolute maximum ratings and thermal dissipation requirements. Ensure that the receiving facility handles bulk-packaged components appropriately to prevent lead damage during storage and assembly processes. Cross-reference the manufacturer part number against internal inventory systems to avoid ordering errors due to similar suffixes.

LED Indication - Discrete Selection Notes

Select this component when a low-profile, diffused red indicator is required for direct panel insertion. The 3 mm diameter and through-hole configuration distinguish it from surface-mount alternatives. Consider the 40 mcd intensity and 645 nm wavelength for standard visibility needs. Evaluate the 1.7 V forward voltage drop against the driving circuit capabilities to ensure proper biasing without excessive current limiting.

LED Indication - Discrete Part Context

This part belongs to Bivar's line of discrete LED indicators, specifically within the T-1 (3 mm) category. It serves as a fundamental optical signaling element for electronic enclosures. Unlike assembled LED modules, this unit functions as a standalone light source intended for integration into custom panel designs or printed circuit boards requiring direct illumination.
