Film capacitors, also known as plastic film capacitors, are electrical components that help filters, couples, and buffers for potentiometers, microphones and DC-to-DC converters. Basically, film capacitors store and discharge electricity in an efficient, cost-effective way.

In a broad sense, film capacitors refer to capacitors made of various layers of film. Due to the process of lamination, the internal electrode is attached to the film. It can also be divided into polyethylene film capacitors and polypropylene film capacitors according to the main component of the film. The specific choice of materials needs to be determined according to the use environment and impact voltage.

The R46KN415045P1M film capacitor is a polypropylene film capacitor in the film capacitor family. It is a non-inductive type with strong interference resistance, low temperature coefficient, excellent self-healing performance, moisture-resistant and metal-proof functions. People can use it in various fields such as audio-frequency circuits, pulse load circuits, DC power supplies and motor control.

As for working principle, this type of capacitor contains two metal plates which are separated by a thin plastic film. Inside the component, the electric charges are stored in the form of electric field. When alternating current passes through, it creates electric waves on the surface of the conductive film. Those waves generate a voltage - known as capacitive reactance - which blocks the electric current from flowing.

Similarly, when the capacitor is in a steady electric circuit, it will store the electrical current and slowly release it. This mechanism allows film capacitors to be used in a wide range of applications ranging from high-frequency to DC circuits, such as AC mains filtering, electric power supplies, vibration and audio applications.

To sum up, the R46KN415045P1M film capacitor has a wide application field and can be used in various circuits. Moreover, it has excellent properties such as high capacitance and low cost. The electric wave principle is the basis for its working.
