Working Principle

The working principle of 940C12P15K is based on the two main characteristics of capacitors - electrical inducibility and capacitance. The capacitor is composed of two electrodes separated by a dielectric material, and the capacitance is determined by the area of the plates, the distance between them, and the dielectric constant of the material between them.

When a voltage is applied, the polar molecules on one side of the dielectric material are repelled, while the non-polar molecules on the other side are attracted, and an electric field is induced in the material. This electric field induces a charge on the two sides of the material, creating a voltage between the two plates. The voltage will cause a flow of current in the circuit, which is the working principle of the capacitor.

The 940C12P15K, compared to other types of capacitors, is characterized by its small size, low leakage current, low loss and high capacitance. It is also resistant to high temperatures, making it suitable for high frequency applications.
