This basic blue 3mm LED is ideal for using as an indicator light – it isn’t too bright to look at, but it won’t be missed! They easily fit in a solderless breadboard or perfboard and are perfect for experimenting. The forward voltage is 3.9V with a current consumption of 20mA. The LED is rated at 15mcd with a view angle of 60°. To use this LED you will need a current limiting resistor; this will vary depending on your input voltage. Typically with a 5V supply we recommend using a 56 ohm resistor for a single LED.
