"Red LED with holder and wire leads. Built in 1/4 W, 680-ohm reistor for 12VDC operation, 1/4" (6 mm) lens diameter, 2.78" overall length, including wire leads, 13/6" mounting hole.
Absolute maximum ratings:
Power dissipation: 180 mW
Forward Voltage: 12V
Forward Current: 15mA
Can I use one of those coin type batteries, like CR2032? Do I have to use a 12V battery? I want to use the smallest batter that I can, as I am making a greeting card.
Thank you to anyone who can help me.
