Common Mode Chokes (also refered to as "CM Chokes") are a type of choke that get their name from their ability to impede common mode currents. They differ from many other chokes, such as differential mode in that they typically use two coils wound around a single core instead of just one. Their primary purpose is to eliminate potential malfunctions in electronic devices and interference in power supply lines -- specifically radio frequency interference (RFI) and electromagnetic interference (EMI).

Selecting or designing the right CM choke takes careful consideration and can depend heavily on the application for which it is intended.
