Feed Through Capacitors

PSM4-131P-15T2 Application Field and Working Principle

The PSM4-131P-15T2 is a feed-through capacitor designed specifically for high frequency and large signal transistors. This type of capacitor uses a combination of an open and a short circuit to reduce the resonance of the signal. It is typically used in transistor circuit design to achieve both high signal fidelity and low impedance.

Application Field

Feed-through capacitors are commonly used in radio frequency and microwave applications, where the transmission of high frequency signals requires high signal fidelity and low impedance. This type of capacitor is most often used for audio applications, such as loudspeakers, amplifiers and sound processors. In these cases, the capacitor can act as a filter, preventing low frequency signals from passing, while still allowing high frequency signals to pass.

Feed-through capacitors are also often used in RF signal transmission systems, such as cell phone towers, television stations, and wireless routers. This type of capacitor is used to reduce the resonance of the signal and thus reduce the signal loss. In these applications, the capacitor is typically placed in the signal path to reduce the effects of interference with other signals.

Working Principle

The working principle of a feed-through capacitor is quite simple. It consists of two separate capacitors, one open and one short, connected in series. The open capacitor acts as a high frequency filter, while the short capacitor acts as a low frequency filter.

When a high frequency signal passes through the capacitor, the open capacitor blocks the signal, while the short capacitor allows the signal to pass. Conversely, when a low frequency signal passes through the capacitor, the short capacitor blocks the signal, while the open capacitor allows the signal to pass. This dual action helps to reduce the resonance of the signal and thus reduce the effects of interference.

Conclusion

The PSM4-131P-15T2 is a feed-through capacitor that is designed to reduce the resonance of a signal in order to improve its fidelity and reduce its impedance. This type of capacitor is used mainly in radio frequency and microwave applications, as well as in audio applications. It consists of two separate capacitors, one open and one short, connected in series, which allows both high and low frequency signals to pass.
