And if it costs a few cents more per unit, the bean counters will overrule it -- or OK it for the samples that go to the FCC, then eliminate it from the production units. 73 Alan NV8A https://www.ele

I've been telling hams for years that they can do a lot with small chokes placed strategically in DC lines, but no, they'd rather blow hundreds of dollars on the amighty ferrite miracle stuff. Merry

What kind of chokes, with what limitations and filtering purposes? A "small choke" is not a panacea for all applications. Please explain yourself more fully. Ray, W4BYG Merry Xmas Rob K5UJ __________

Sure--here's an example: You have some piece of equipment that uses relays, the kind that are small pc board mounted jobs. Maybe they switch when you go from transmit to receive. They have 12 v. DC

Some of the ferrite "small chokes" (inductors) work well since the DC resistance is low and the SRF is high. Others not so good with high R and SRF well below 1MHz, so might work for some RFI but not
