I have a question about iron powder toroidal inductor heating... I built an experimental PA for 137 kHz. Details can be seen here: http://blog.n1bug.com/ For the three inductors I've used T157-2 core
Hello N1BUG, Paul, I would have thought what wire was NOT wound on the toroid would also get hot if the current carrying capacity of the wire was inadequate. Is that the case? Have you got a thermoco
Thanks Chris, I think the wire NOT wound on the toroid is warming also, but it is difficult to know. The leads are very short and soldered to large pads on the circuit board which tend to act as a he
Hello N1BUG, The core, being dust iron, must have good heat transfer, so i would expect the whole core would heat to much the same temperature, even if the wire itself was the source of the heat. Can
