3mm Red / Green Bi-Colour 3 Pin LED (Common Cathode) ATmel Supports 3 types of FMA small red and green bi color 3mm light emitting diode with a common cathode that produces consistent light and consumes little power, contained in a milky white packaging. It is suitable for PCB or panel mounting. In a shared cathode design, diodes are linked. The common cathode is the center leg, and it is the place where a resistor should be installed for the protection of the LED. Pin Configuration Pin Name Description Anode Positive terminal of
