⭐ 5mm CBI LED – Bi-Color Circuit Board Indicator | High-Reliability Panel LED

The 5mm CBI LED (Circuit Board Indicator LED) in bi-color configuration is a highly reliable and versatile panel indicator LED designed for applications requiring clear dual-status signaling. As a PCB-mountable 5mm CBI LED, it provides engineers, manufacturers, and equipment designers with a durable, bright, and space-efficient light source suitable for communication equipment, instrumentation, industrial controls, and consumer electronics.

This bi-color 5mm CBI LED uses a dual-chip or 3-pin structure, allowing two distinct colors—or blended mixed colors—within one compact indicator package. With its rectangular black housing, the LED offers excellent contrast and high visibility even in bright environments, making it ideal for mission-critical status indication.

🔧 Technical Advantages

1. Precise PCB Alignment

The pre-formed leads ensure repeatable, accurate mounting, reducing production errors and maintaining uniform height and orientation.

2. Superior Contrast for Status Display

The black housing minimizes light leakage and maximizes front-view visibility, improving readability during equipment operation.

3. Multi-Status Signaling

Bi-color LEDs allow:

• Red/Green for ON/OFF

• Green/Yellow for standby

• Red/Yellow for warning or fault

• Mixed color blending for a third color output

This flexibility reduces the number of indicators required per panel.

4. Excellent Electrical Performance

• Low forward voltage

• Efficient low-current operation

• IC-compatible and microcontroller-friendly
