Feed-through capacitors are characterized by their ability to provide capacitance to RF signals by allowing the passage of current through two connected terminals. This type of capacitor behaves as both an AC and DC coupling device, and has become an increasingly important component for inter-stage coupling, bypassing, and filtering of various electronic applications. The PSM4-680M-20T2 is an innovative feed-through capacitor developed by Pucheng Technology. It is designed for the RF filtering applications, and this paper will discuss its application field and operation principle.

The PSM4-680M-20T2 is an advanced design feed-through capacitor that utilizes a specially-shaped non-magnetic housing. This design allows the capacitor to provide optimal shielding of RF signals while providing appropriate ground isolation. The internal connection between the two terminals of the capacitor is made with silver-coated contacts to ensure superior electrical performance with low contact resistance. The PSM4-680M-20T2 is designed to handle a maximum RF power of 25dBm.

The PSM4-680M-20T2 is applicable in a variety of applications. It can be used in the filtration of RF signals in wireless communication networks, including cellular base stations, satellite communication equipment, and cellular handsets. It can also be used in RF filtration for medical applications, such as MRI or X-ray systems. In addition, the PSM4-680M-20T2 can be used in various electronic control systems, including the control of industrial automation systems. The high power handling capability of the PSM4-680M-20T2 makes it suitable for use in high power RF signal applications.

The PSM4-680M-20T2 operates on a simple working principle. The capacitor consists of two metal plates, both held in a housing. The two metal plates are connected by an insulator that provides an appropriate path for DC current and capacitance. When a RF signal passes through the two terminals of the capacitor, the RF signal is distributed across the two metal plates and modulates the capacitance between them. Through this process, the capacitor is able to provide capacitance for the RF signal while also filtering out undesired signals.

Overall, the PSM4-680M-20T2 is an advanced feed-through capacitor designed for RF filtering applications. It utilizes a specially-shaped housing to provide proper RF screening and ground isolation. The internal contacts are silver-coated and are designed to provide low contact resistance. It is capable of handling a maximum RF power of 25dBm and is applicable in a variety of RF filtration applications, such as cellular base stations and industrial automation systems. The capacitor operates on the simple principle of allowing a RF signal to modulate the capacitance between two metal plates.
