A DR (Differential-mode to common-mode) inductor is a type of inductor used to suppress common-mode noise in electronic circuits. It is designed to provide high differential-mode impedance while providing low common-mode impedance. This makes it effective in reducing the common-mode noise generated by differential-mode signals while maintaining the integrity of the differential-mode signals. It is commonly used in power supply designs, audio equipment, and other electronic devices where common-mode noise must be minimized. DR inductors are also known as common-mode choke or CM choke.
