Dears.
I assume this component is an inductor as it is labeled with "L2", but what is the value of it?
it got only one brand coding "black".
thank you

It may indeed be a zero ohm jumper, and the L2 designation of the location could be for other variations of the design using the same board. I see that a lot. Often, in cheap switcher power supplies there will be runners to allow multi section mains filtering but the chokes will be replaced with jumper wires.
If the TS can get hold of a meter that can measure the resistance of low value resistors then they can measure and know.

Yeah, my guess would be a simple jumper.

The "L2" designator may have been a prior design revision where a real inductor was planned but, in post-production and field tests, a simple jumper was considered good enough. It happens quite often.

Thank you all for the help. After considering your answers and looking at the circuit again, yes it i most likely only a jumper wire.
The circuit got 4 of them L1 to L4.
Im new to electronics and your help is highly appreciated
Thank you again
