About this episode

This episode discusses common pitfalls in selecting common mode chokes for EMI suppression.

Selecting the right common mode choke (CMC) can make or break your EMI suppression strategy, but it's easy to fall into common traps. In this episode of "Common Pitfalls of the Common Mode Choke," we highlight the errors most often made during CMC selection, such as focusing only on inductance or overlooking the importance of core material and geometry. You'll learn the practical differences between inductance and impedance, how construction affects performance, and a straightforward workflow for choosing the best CMC for your application.
