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.
2mm Flat Top Cylindrical Bi-Color LED Diode (3-Pin) – Compact Dual-Color Indicator for Precision Electronics
The 2mm flat top cylindrical bi-color LED diode (3 pin) is engineered for compact electronic devices that require accurate multi-status indication in minimal space. Designed with a flat-top cylindrical lens, it delivers uniform, wide-angle illumination and excellent readability even when viewed from the side.
This component integrates two colors in one LED package, offering a versatile signal solution for advanced electronics, instrumentation panels, and compact consumer products. With a 3-pin configuration—two independent LED chips and one common lead (anode or cathode)—it supports flexible control and compatibility with low-voltage digital circuits, microcontrollers, and IC-based systems.
Its small size, efficient optical output, and robust construction make it a preferred LED for engineers, product designers, and OEM manufacturers requiring reliable, space-saving dual-color indication.
