    Hi i was just stripping a circuit bored for parts. I know all the normal stamps like F for fuse CN for connector D for diode etc but there are 3 components labeled L1 L2 L3. Two look like diodes one like a capacitor. they have no markings on at all other than whats on the board. Any body know what thay are?

    Inductors.

    They are encapsulated coils of wire, essentially.

    Handy to save, especially the larger value ones. They markings can be deciphered as to their value in Henrys usually uH or nH, like capacitors.

    Ahh Thank you i know about inductors just didn't know that was there abbreviation. I'm used to seeing wire wrapped round ferrite rings like on PC motherboards. Thank you once again
