Hello,
Some of the phenolic (non-ferrite) inductors in a board are burning up when going towards 50W at around 10MHz. They are in a simple lowpass Pi-filter, meaning not a very resonant filter. We'll move to the Gowanda
21M series now which will hopefully do but it'll still have its limits. If we need bigger it'll be custom.Does anyone know another source for off-the-shelf inductors that are 10% or better and where one can have 910nH and 1uH? Ferrite is pretty much out because of losses. One issue on smaller air/phenolic inductors is that they don't use Litzwire and then the skin effect gets ya.
Digikey doesn't seem to have anything there and the search engines at Newark and Mouser are IMHO useless.
