UU10.5 Common Chess Inductance

UU10.5 Common Chess Inductance

UU10.5 Common Chess Inductance, also called common mode choke, it is often used to filter common mode electromagnetic interference signals in computer switching power supply. In the board design, the common mode inductor also plays the role of EMI filtering, which is used to suppress the outward radiation of electromagnetic wave generated by high-speed signal line. Application: Generally used in the cost control is more strict, or the occasion of small power; Our products meet EU standards and are exported to China and other countries all over the world.

Product Description


1. Product Introduction of UU10.5 Common Chess Inductance


UU10.5 Common chess 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.
