Feed Through Capacitors

Application Field and Working Principle of PSM4-101M-15B

Feed Through Capacitors, also known as X capacitor, is an important measure for high frequency signal EMI interference reduction and conducted radiation control. In recent years, the ever-increasing demands for miniaturization, high capacitance and high reliability have accelerated PSM4-101M-15B development.

The main application fields of PSM4-101M-15B are: automotive electronics, military communications, medical electronics, space flight and so on. With advantages such as small size, large capacity, low insertion loss, high insulation resistance, high dielectric strength, high rated voltage, stable performance, strong anti-interference ability, good reliability, etc., it has made great contribution to EMI suppression in the circuit.

In the traditional production process, PSM4-101M-15B is made by means of surface discharge under high voltage. It takes ceramic as dielectric material to form a 3D comb structure, which is embedded in a metal case. The metal case is of two parts, with one part called outer sleeve and the other part called inner sleeve. The insulating sleeve and internal dielectric matrix are used to finish the seal welding. This structure makes the capacity and impedance of the connected inner and outer terminals consistent.

The working principle of PSM4-101M-15B is complex. It can be divided into three stages in a complete cycle of work. First, when the voltage is applied between the two interfaces, electric field lines will be formed. Secondly, the electric field will accelerate the positive and negative ions in the medium, and their motion will promote the rearrangement of the dielectric dipoles in the dielectric material. Finally, the dipoles rearrangement produces a new charge to keep the material in displacement field polarization, which produces an electric current, thus realizing the ultimate goal of EMI suppression and conducted radiation wave field control.

In short, PSM4-101M-15B has wide application in the field of EMI suppression. It is known for its small size, large capacity, low insertion loss, strong anti-interference ability and good reliability. Therefore, it is highly popular among electronics engineers.
