3SYD-201-S

LED Indication - Discrete Overview

The Bivar Inc. 3SYD-201-S is a T-1 (3mm) through-hole LED indicator featuring a yellow diffused lens and an extended profile design. It operates with a forward voltage of approximately 2V and emits light at a wavelength of 700nm. The component provides a viewing angle of 35 degrees and offers a luminous intensity of 2mcd, making it suitable for applications requiring visibility in higher ambient lighting conditions.

LED Indication - Discrete Feature Summary

• Extended profile construction provides additional protrusion for improved visibility in specific mounting scenarios.
• Diffused lens technology ensures uniform light distribution across the indicator surface.
• Through-hole radial packaging facilitates standard PCB integration.

LED Indication - Discrete Applications

• Equipment status indication in high ambient lighting environments
• Front panel visual signaling for industrial control systems
• Power supply status monitoring

LED Indication - Discrete Procurement Notes

Verify that the procurement source explicitly confirms the 'extended profile' characteristic, as this distinguishes the part from standard T-1 LEDs. Ensure the supplier documentation matches the exact suffix '3SYD-201-S' to confirm the yellow diffused color and 2V forward voltage specifications. Cross-reference the datasheet to validate the 35-degree viewing angle and 2mcd intensity requirements before finalizing the order.

LED Indication - Discrete Selection Notes

Select this component when standard T-1 LEDs lack sufficient physical protrusion for the intended enclosure depth or panel thickness. The extended profile is critical for applications where the LED must sit above the mounting surface to ensure adequate light exposure. Verify that the 35-degree viewing angle aligns with the operator's line of sight and that the 2mcd intensity meets visibility standards for the operating environment.

LED Indication - Discrete Part Context

This component belongs to the Bivar T-1 series of discrete LED indicators. Unlike standard flat-profile LEDs, the 3SYD-201-S variant features an elongated body designed to extend beyond the PCB plane. This design addresses spatial constraints in dense assemblies while maintaining the standard 3mm diameter footprint common to T-1 packages.

LED Indication - Discrete Replacement Considerations

Direct substitutes include other Bivar T-1 extended profile LEDs with matching yellow diffused lenses. Verify that any replacement maintains the 2V forward voltage and 35-degree viewing angle to ensure consistent performance in existing designs.

LED Indication - Discrete FAQ

What is the primary advantage of the extended profile design?

The extended profile allows the LED to protrude further from the PCB, which is beneficial for applications requiring visibility in high ambient lighting or where the LED needs to be positioned above the panel surface.

What is the viewing angle of the 3SYD-201-S?

The component has a viewing angle of 35 degrees, providing a focused beam of light suitable for directional indication.
