I can’t find what kind of component the black one with 150 on it is. I thought a condensator but i can’t find anything resembling.
Part of a Netgear prosafe m4100-50g-poe+ network switch.
Hi @gmantunt Normally there are some tell tale sign at the pcb components, e.g. C = Capacitor, the picture, i would say is an inductor. It should be Label as L xx on the PCB The number 150 indicates the value 15uH if im not wrong, and btw what is the issues with this POE switch?
It looks like a 150ohm inductor coil to me, or it may be 15uH like @salmonjapan said. Take it off of the board and check it with an ohm meter, and see for sure.
