Obtain 3D specification files
To examine all 3D specifications, save the files to your local drive and open them with your 3D application.
Lens colors in 3D files are solely for visual representation; consult the Datasheet for accurate lens type and color information.
In the event of a mismatch, the dimensions in the datasheet take precedence over the 3D specifications.
3mm Bi-Level LED CBI (11×4×10 mm), Dual-Position Circuit Board Indicator
The 3mm Bi-Level LED CBI is engineered for compact, multi-status indication in modern electronic devices where board space is limited but reliability is critical. Built in a bi-level configuration, this indicator provides two vertically stacked LED positions, enabling clear two-stage signaling within a single compact footprint.
Designed with versatility in mind, this CBI is available in many color combinations including single-color, bi-color, and tri-color LED options—ideal for displaying multiple states such as ON/OFF, warning/normal, or multi-step status signals.
Constructed using a UL 94V-0 rated PA66 housing, the unit ensures flame-retardant performance, long-term durability, and excellent optical contrast. Its pre-formed leads guarantee accurate PCB alignment, simplifying assembly and delivering consistent illumination performance across both LED levels.
