In Reply to: Re: That '22 mH' choke may have an inductance of 22 mH at 10 KHz, but not at 120 Hz. posted by Ray Moth on April 20, 2007 at 15:22:34:
All ferrous core chokes exhibit varying inductance over frequency, so much so that specifying one without the other is almost meaningless. The formula for XL is obviously based on the actual inductance at the frequency of operation.
