    So i found a transformer in my junkbox, the problem is that I've only worked with "normal" transformer, not pcb mounts/smps ones. How do i identify the primary and secondary winding since it has multiple pins? On my other transformers i just measure the resistance and the one with highest is the primary but this doesn't work on this (all pins show 0 resistance)

    The transformer i have looks almost exactly like this only different wires on the pins:
