Time:2019-04-28 13:37:24 Click:

There are five working voltage of common various colors LED for your reference:

 

White LED is 3.0–3.4V; Red LED is 1.8–2.2V; Blue LED is 3.0–3.2V; Green LED is 2.9–3.1V; Yellow LED is 1.8–2.0V.

 

PS: SMD LED voltage is basically equal to twin-lead DIP LED one; Their current generally is 20–60mA, some of them will over 100mA.
