Parasitic inductance of the interconnect / wires / leads at high frequencies.Actually, for some applications (RF decoupling), multiple caps are preferred to a single (larger) cap, for this very reason. It must be evaluated case by case.
Hi All,A choke is submitted to significant DC current. It must be gapped. The minimum gap is butt-stacked, but it's not enough, so it is necessary to add cauls. The thickness of the cauls modify significant the Al coefficient. There are probably tables that give the Al as a function of the core size and gap thickness.
Wanted to wind my own inductor to try out different values for a 50 watt valve amp.
I have quite a few left over lams which I think are EI- 75s, I have some bobbins but could make a few more if needed.
Just needed to know wire gauge and winds for getting a 3H @ 250ma at about 112ohms dcr.
If anyone could help please?
