Question about self resonant frequency for inductor

[guillaumechen]

Hi everyone,

I use a PQ core to build an inductor (one winding), but the resonant frequency is approaching to the minimum requirement. How can increase the self resonant frequency for the inductor?

Thanks!

You should increase the separation between wire windings. This is because each winding is capacitively loaded by the other near windings.

Thank you so much, I will try it.
