Q.At which frequency is the "impedance," which is the representative characteristic of common mode filters / chokes, defined?

EMC Components >  EMC Components >  Common Mode Filters / Chokes

A. The impedance of common mode filters (common mode chokes) is mainly defined at 100MHz.
You can confirm the impedance for each product in catalogs or on the product details page.
On the product details page, you can view even more detailed in the form of an impedance curve.
