Common Mode Chokes (CMCs) are crucial for suppressing noise in electronic systems but there's more to them than meets the eye. While they are known for filtering unwanted common-mode signals in power and data lines, understanding their internal behavior, simulation accuracy, and extended use cases can unlock entirely new possibilities.
In this application note, we explore the WE-CMDC series not only through theoretical insights and LTspice simulations but also through real-world measurements and unexpected circuit applications. From precise equivalent circuit modeling to using CMCs in oscillators or DC-DC converter filters, this guide reveals how these compact components can become powerful tools beyond conventional filtering.
