With a chonky 12V 25A power supply and my trusty electronic load, we dial up one amp at a time... note that all PTC fuses have a 'hold' of 5A and a higher trip current of ~2x that, so we actually open at 10A. Once it heats up a bit, that trip current can drop a bit, but it will always be over 5A and under 10A. Good test equipment makes this job nice and easy. The board is complete - time to book it up, just in time for the New Year.
