SMD Common Mode Chokes

SMD Common Mode Choke are often used to filter common-mode electromagnetic interference signals in switching power supplies of computers. In the board design, the common-mode inductor also plays the role of EMI filtering, which is used to suppress the electromagnetic wave generated by high-speed signal lines.

In general, pay attention to select the frequency band required to be filtered at the same time, the larger the common-mode impedance is, the better. Therefore, when selecting the common-mode inductor, it is necessary to look at the device data, mainly according to the impedance frequency curve. In addition, attention should be paid to the impact of the differential mode impedance on the signal during selection, mainly focusing on the differential mode impedance, especially the high-speed port

Common Mode Chokes

Toroidal common mode inductor is a special inductor,

which is widely used in power circuits of wireless communication

and electronic equipment. Toroidal common mode inductors are

favored by many engineers because of their small size and low cost

and high inductance value.

Because of its unique structure, Toroidal common mode inductors

can overcome the problems existing in traditional inductors, such as

large volume, heavy mass, large power loss, short life, etc. In addition,

it also has good electromagnetic compatibility, can be used in different

environments, not susceptible to external electromagnetic noise.

In addition, Toroidal common-mode inductors have good thermal stability

and can operate in high temperature environments without changing their

inductance value due to temperature changes. In addition, its insulation

performance is also better, can effectively avoid short circuit and heat loss.

The advantages of Toroidal common mode inductors are not only reflected

in their physical structure, but also in their electrical properties.
