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.
