Pro Signal 5mm Bi Colour LED (Yellow/Green and Red), Pack of 50

The Pro Signal PSG91923 is a pack of 50 high-quality, 5mm diffused common cathode Bi Colour LEDs. These versatile components are designed for through-hole mounting and feature a classic round lens shape, making them ideal for a wide range of electronic projects, prototypes, and indicator applications where clear, dual-colour signalling is required.

Each LED in the pack can display two distinct colours from a single component: a bright red and a green. As a common cathode type, they share a common negative connection, simplifying circuit design and wiring. The diffused lens provides a wide, even light distribution, perfect for status indicators, panel lights, and decorative electronics where a softer, non-glaring light output is preferred.

Engineered for reliable performance, these LEDs are specified with precise electrical characteristics. They operate with a forward current of 30mA for both the red and green elements, with a corresponding forward voltage of 2.4V. The luminous intensity is a robust 600mcd for the red and 200mcd for the green, ensuring good visibility. The reverse voltage rating of 5V provides a degree of protection against incorrect polarity connection.

This pack of 50 offers excellent value for hobbyists, students, and professionals undertaking batch production or requiring multiple units for testing and development. The compact through-hole design makes them easy to integrate onto printed circuit boards (PCBs) using standard soldering techniques.
