3HDL-S

LED Indication - Discrete Overview

The Bivar Inc. 3HDL-S is a high-efficiency red light-emitting diode designed for through-hole mounting applications. It features a 3mm (T-1) radial package with a diffused lens to provide a wide viewing angle of 40 degrees. The device emits light at a peak wavelength of 625 nm and offers a typical luminous intensity of 2.5 mcd. It operates with a forward voltage of 2V DC at a test current of 2 mA, making it suitable for low-power indicator circuits.

LED Indication - Discrete Feature Summary

• High-efficiency red LED construction optimized for visibility in indicator applications
• Diffused dome lens design providing a standardized 40-degree viewing angle
• Radial through-hole package configuration compatible with standard PCB layouts

LED Indication - Discrete Applications

• Panel status indicators for electronic equipment
• Low-power visual signaling in control systems
• General-purpose component indication in consumer devices

LED Indication - Discrete Procurement Notes

Verify the specific datasheet version from authorized distributors to confirm exact binning parameters for luminous intensity and wavelength. Ensure that the supplier provides original manufacturer documentation to validate the 3mm radial package dimensions and lead form specifications before finalizing procurement orders.

LED Indication - Discrete Selection Notes

Select this component when a diffused red indicator with a moderate viewing angle is required for panel mounting. The 2V forward voltage and 2mA operating current make it appropriate for direct interfacing with standard logic levels or current-limited drivers without excessive heat generation.

LED Indication - Discrete Part Context

This part belongs to Bivar's discrete LED indication series, which specializes in through-hole components for industrial and commercial electronics. The 3HDL-S variant specifically addresses applications requiring a balance between visibility and power efficiency within a compact 3mm form factor.

LED Indication - Discrete Replacement Considerations

Consider the 3HDL-201-S if an extended lens with a narrower 35-degree viewing angle is preferred. Verify pin compatibility and spectral output alignment when substituting with other 3mm red LEDs from different manufacturers.
