Some one sent me an email and said these will do the job. Ceramic capacitor disk 10KV/1000pF. Do you think these would work?


Some ceramic capacitors have the value change with the instantaneous applied voltage. I know somebody who tried to use one in a tuned circuit - complete disaster. Do not use the ones that are meant for power supply bypassing.

This is my first attempt at making traps and I do not fully understand how they work. I am willing to learn as this is what makes the hobby great but I cannot find enough step by step info to lead me in the right direction.


Thanks

What sort of capacitors can I use in parallel in making some 7MHz and 3.7MHz wire wound traps?

I've had good luck with door-knob caps.
