Presumably Vf refers to voltage drop properties and Ifmax refers to maximum current (before it blows?).
These all vary So how do I select a compatible one for the circuit? Or is it as simple as chatting to fuzzdog?
Just V=IR and you can work out your min resistor value based on the LED’s max current.
I said maybe.....
So taking a 2200 ohm CLR, and a 9v circuit, am I right in thinking 4mA would be the correct current? Therefore I could select any led as they all seem to handle up to 20mA. (Sorry about the basic questions)!
I said maybe.....
thanks in advance all
