3mm Bi-Level LED CBI (8×4×10mm), Circuit Board Indicator
⭐ 3mm Bi-Level LED CBI – Compact Dual-Level Circuit Board Indicator for Precision Signaling
The 3mm Bi-Level LED CBI (Circuit Board Indicator) in an 8×4×10mm compact housing is engineered for applications requiring stacked, dual-position visual indication within restricted panel spaces. This bi-level configuration provides two vertically aligned indicator points, enabling clear multi-status signaling without increasing PCB footprint. Whether used in control panels, test instruments, or communication devices, this Bi-Level CBI guarantees reliability, clarity, and long operational life.
Built around a 3mm LED package, this indicator series supports a wide variety of single-color, bi-color, and multi-color combinations, allowing engineers and product designers to customize display behavior based on operational requirements. The design integrates pre-formed leads, ensuring consistent PCB alignment across both levels, simplifying the assembly process and improving installation repeatability.
🔧 Key Features
✔ Dual-Level CBI Design
The Bi-Level CBI structure stacks two LEDs vertically, enabling two distinct indication points in one compact module. This makes it ideal for multi-status signaling, such as “power + warning,” “run + error,” or other dual-state conditions.
✔ Compact 8 × 4 × 10 mm Housing
This small footprint is optimized for dense PCB layouts, miniature devices, and compact instrumentation where saving space is critical.
✔ 3mm LED Package
The standard 3mm through-hole LED size provides:
-
High brightness
-
Wide viewing angles
-
Compatibility with most indicator designs
✔ Pre-Formed Leads for Precise Alignment
Each LED is supported by pre-formed leads that ensure:
-
Consistent vertical alignment
-
Quick and repeatable PCB installation
-
Accurate level-to-level spacing
✔ High-Contrast Black Housing
The black PA66 housing enhances LED visibility by reducing ambient light reflection. This ensures clear ON/OFF indication even in bright environments.
✔ Long-Life, Stable LED Chip
High-quality LED chips deliver:
-
Uniform luminous output
-
Excellent stability
-
Extended service life
-
Low power consumption
✔ Safety & Compliance
-
UL 94V-0 rated PA66 housing for flame resistance
-
Halogen-free
-
Fully RoHS compliant

Selectable single-color, bi-color, or dual-LED combinations enable:
-
Red/Green (most common)
-
Red/Yellow
-
Red/Blue
-
Green/Yellow
…and more.
✔ Reliable & Consistent Performance
The mechanical resilience of the PA66 housing combined with pre-formed leads results in low failure rates and long-term stability.
📘 Case Study: Compact Diagnostic Meter Upgrade
A manufacturer of portable diagnostic meters needed a way to show:
-
Power ON
-
Measurement Active
Originally, two separate LEDs were placed horizontally, taking valuable PCB space. After switching to the 3mm Bi-Level CBI, the company achieved:
-
30% PCB space savings
-
Cleaner, more professional front panel layout
-
Improved visibility for technicians in field conditions
-
Reduced assembly time due to the aligned CBI geometry
This upgrade contributed to a 15% reduction in production cost and enhanced customer satisfaction.
