UU16 Common Mode Inductance

​1. Product Introduction of UU16 Common Mode Inductance

UU16 common mode inductance filter circuit. La and Lb are Common Mode Inductance coils. The two coils are wound on the same core in the same number of turns and in the same phase (wound in reverse). In this way, when the normal current in the circuit flows through the common mode inductor, the current in the same phase winding inductor coil generates reverse magnetic field and cancel each other, the normal signal current is mainly affected by the coil resistance (and a small amount of damping caused by leakage inductance);

When the common mode current flows through the coil, due to the homogeneity of the common mode current, the magnetic field in the same direction will be generated in the coil and the inductive reactance of the coil will be increased. As a result, the coil will show high impedance and produce strong damping effect, so as to attenuate the common mode current and achieve the purpose of filtering.

Our high-quality UU common mode choke solves low differential mode noise signal suppression interference sources for customers, and is deeply loved by customers in China, Europe and America.
