3BWD

LED Indication - Discrete Overview

The Bivar Inc. 3BWD is a through-hole, single-color blue LED component designed for panel indicator applications. It features a rectangular lens with diffused transparency and a tinted finish. The device operates at a forward current of 20 mA with a typical forward voltage of 4 V. It emits light at a peak wavelength of 430 nm with an intensity of 4 mcd. The unit has a T-1 (3mm) lens size, measures 4 mm in height, and is supplied in bulk packaging.

LED Indication - Discrete Feature Summary

• Through-hole mounting configuration for standard PCB assembly
• Rectangular lens shape with diffused transparency for uniform light distribution
• Blue emission optimized for visual status indication

LED Indication - Discrete Applications

• Panel-mounted status indicators
• Electronic equipment front panels
• Control board visual signaling

LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix required for your application, as variations such as 3BWD-F or 3BWD-S exist with different lead times or configurations. Confirm RoHS compliance status directly from the manufacturer datasheet before procurement. Check regional availability as stock levels may vary by distributor region.

LED Indication - Discrete Selection Notes

Select the 3BWD when a blue, through-hole indicator with a rectangular form factor is required. Ensure the circuit design supports a 4 V forward voltage drop at 20 mA. Consider the 430 nm wavelength for visibility requirements. Verify that the 4 mm height fits within the enclosure constraints.

LED Indication - Discrete Part Context

The 3BWD belongs to Bivar’s discrete LED indicator line, specifically the T-1 series. It is distinct from multi-color variants like MPR3BC and wire-equipped panel mounts like 3BWD-S. This component represents a standard single-color solution for basic visual feedback needs.

LED Indication - Discrete Replacement Considerations

Direct substitutes include Bivar part numbers 3BWD-F and 3BWD-201. These variants share the same core LED specifications but may differ in packaging or lead time. Cross-reference with other manufacturers' 3mm blue through-hole LEDs only if electrical parameters match exactly.
