We wish to use Power inductors for filtering SMPS. We want them to have as little interwinding capacitance as possible because we want to maximally impede the high frequency common mode noise from getting through this stray capacitance.
As you know, interwinding capacitance is not listed in inductor datasheets, so please could you confirm that the “Self Resonant Frequency” is what we need to use to calculate this stray capacitance?
Thats is, w = 1/[(sqrt(LC)]
Therefore C = 1/(w^2 * L)
