plastic film capacitor is mainly used in signal circuit as a coupling device. It is widely used in medical instruments, audio devices, military products and various kinds of communication system. The PH04-7,50 product is a plastic film capacitor, and its main application fields can be divided into three categories: filter, coupling and bypass.

Filter application: In the signal circuit, many signals can interfere with each other, such as the radio signal and the audio signal, and the acoustic signal and the power supply frequency signal, etc., and the filter application can eliminate the interference of these signals. The PH04-7,50 product has the characteristics of high frequency, high quality factor and low equivalent series resistance, effectively filtering unwanted signals,high-performance filter circuit can be completed.

Coupling application: The coupling application is mainly used for capacitor components in the signal circuit. It is mainly used to isolate the frequency band, block DC, and transmit the AC signal. The PH04-7,50 product has a high insulation resistance, which can be used to isolate the components from the power grid and the signal components, reduce noise, effectively transmit the signal, and improve the signal-to-noise ratio.

Bypass Application: Bypass application can block AC current, transmit DC current, and resist current by blocking AC current. The PH04-7,50 has a wide range of applications in the bypass circuit, such as providing high frequency current, and filtering small and medium signals. The PH04-7,50 also has the characteristics of low leakage current and good temperature resistance, which can effectively reduce noise and provide high accuracy for the circuit.

In addition, PH04-7,50 also has the characteristics of large size, small volume, light weight, low cost, etc. Its working principle is mainly based on the idea of forming a complete conductive path for electrons to pass through when connecting. When the two wires of a capacitor are electrically connected, a capacitor charge-discharge process occurs, and a certain voltage is produced.

To sum up, PH04-7,50 is a plastic film capacitor with a wide range of applications, mainly used in filter, coupling and bypass circuits. It has the characteristics of small size, high insulation resistance and low equivalent series resistance, and its working principle is based on the principle of forming a complete conductive path for electrons to flow.
