Film capacitors, also called plastic-film (PET) capacitors, are capacitors manufactured with a thin plastic film to separate the two electrodes. They are often used in high-actuator applications such as switching power supplies, high voltage applications, and high-speed transient signals. The C878BF35120SA0J is a film capacitor with a wide range of use, combining high capacitance and long life.

Application Field

The C878BF35120SA0J is specifically designed for high-end applications, such as high-speed switching, high frequency, pulse/pulse random-like signal, and more. It is a special kind of film capacitor, which offers both improved performance and ultra-low ESR. This type of capacitor also has excellent long-term stability and low loss ratings, making it an ideal choice for high-end applications with strict requirements.

Working Principle

The working principle of a film capacitor is pretty simple. A dielectric material is sandwiched between two electrode plates. When voltage is applied to the capacitor, the dielectric material between the electrodes is attracted by the electrostatic force. As the voltage increases, the electrostatic force attracts more charge, thus increasing the capacitance. This phenomenon is known as dielectric polarization.

When a capacitor is in use, charge builds up on the plates, and the electrostatic field grows stronger. This increase in the electrostatic field causes the dielectric material to become more polarized, which further increases the capacitance. The C878BF35120SA0J utilizes this electrostatic effect to provide efficient and reliable performance.

Film capacitors also employ a self-healing property, which allows them to withstand repeated surges without any damage. This property is due to the fact that when the insulation layer between the electrodes is damaged, the currents are conducted along the regenerating paths which are formed by the gas and metal ions.

The C878BF35120SA0J film capacitor offers excellent performance, making it an ideal choice for high-end applications. It provides excellent long-term stability and low ESR, and its self-healing property ensures a reliable and continuous service life. With its wide range of use, it is no wonder that it is one of the most popular film capacitors on the market.
