3BC

LED Indication - Discrete Overview

The Bivar Inc. 3BC is a standard metal panel mount indicator featuring a 3mm bi-color high-efficiency LED with red and green illumination. It utilizes a white diffused dome lens to provide a 45-degree viewing angle. The component operates at a forward current of 20 mA, with typical forward voltages of 2 V for the red LED and 2.1 V for the green LED. Peak wavelengths are specified at 625 nm for red and 568 nm for green, each producing an optical intensity of 6 mcd. Designed for direct panel installation, it requires a 6 mm mounting hole and includes nut and washer hardware. The unit features straight leads measuring approximately 15.6 mm in length and functions within a temperature range of -40°C to +85°C.

LED Indication - Discrete Feature Summary

• Bi-color LED configuration providing distinct red and green indication through a single diffused lens assembly
• Standard metal housing designed for secure panel mounting using included nuts and washers
• High-efficiency light output with a wide 45-degree viewing angle facilitated by a domed lens

LED Indication - Discrete Applications

• Status indication on electronic equipment front panels
• Power state signaling in industrial control systems
• Visual alerts in medical device interfaces

LED Indication - Discrete Procurement Notes

Verify the specific suffix variant required for your application, as Bivar distinguishes between standard (e.g., MPC3BC) and recessed (e.g., MPR3BC) configurations. Confirm that the lead length and operating temperature range meet your design constraints. Ensure the panel cutout diameter matches the specified 6 mm requirement for proper fitment. Cross-reference datasheets to confirm RoHS compliance status for your region.

LED Indication - Discrete Selection Notes

Select this component when dual-state visual feedback is necessary within a compact 3mm footprint. Consider the recessed variant if surface flushness is critical, or the standard version for general visibility. Evaluate the 20 mA drive current against your available power supply capabilities. Verify that the 625 nm and 568 nm wavelengths align with your visibility requirements under ambient lighting conditions.

LED Indication - Discrete Part Context

This indicator belongs to Bivar's standard line of metal panel mount LEDs, which are engineered for durability and clear visual signaling. The series typically offers various lens colors and lead configurations to suit different enclosure designs. These components serve as fundamental interface elements for communicating operational states in hardware systems requiring reliable, long-lasting illumination.

LED Indication - Discrete Replacement Considerations

MPR3BC provides a recessed alternative with identical electrical characteristics but differs in physical protrusion and lead length.
