Bi-Color Circuit Board Indicator 3mm LED – Single-Level CBI
A compact, high-contrast indicator solution for modern electronic equipment.
The bi-color circuit board indicator 3mm LED (single-level CBI) is engineered for precision status indication in compact electronic assemblies. Built with a 3mm bi-color LED integrated into a single-level CBI housing, this component delivers reliable dual-state signaling, excellent on-panel visibility, and efficient PCB alignment. Designed for demanding industrial, commercial, and consumer applications, it provides long-life performance with a variety of color combinations—ideal for multi-status displays where space is limited.
Key Features
✔ Single-Level CBI Construction
The LED is mounted in a molded housing that ensures perfect vertical alignment on the PCB, enabling clean panel presentation and consistent optical output.
✔ Bi-Color Dual-State Indication
Two-chip bi-color configuration allows:
-
Two distinct colors (ex: Red/Green, Yellow/Green, Blue/Green, etc.)
-
Mixed-color appearance when both chips are driven simultaneously
This makes it suitable for standby/active, normal/warning, and power/status indication schemes.
✔ Precision Pre-Formed Leads
Leads are shaped for:
-
Easy insertion
-
Repeatable positioning
-
High-speed automated assembly compatibility
✔ High-Contrast Black Housing
The black PA66 housing:
-
Increases contrast for improved visibility
-
Minimizes stray reflections
-
Delivers a clean, professional panel appearance
✔ Durable PA66 UL-Rated Body
-
UL 94V-0 flame-retardant
-
Impact-resistant
-
Excellent dimensional stability
✔ RoHS & Halogen-Free
Fully compliant with environmental and industry safety standards.
