Film Capacitors

Film capacitors are capacitors that use a metal or plasticized film as an electrically-conductive layer to store electrical energy and act as the dielectric of the capacitor. They consist of two electrodes, separator, and an electrical insulation film. Film capacitors offer high-capacitance, long-life, and low loss characteristics. Due to these benefits, they are widely used in high frequency applications, signal processing, pulse power systems, multi-phase applications, and other high-performance systems.

683PSB202K2H Application Field and Working Principle

The 683PSB202K2H film capacitor is designed for use in power supply applications. It offers a wide capacitance range, low ESR, low ESL, and high ripple current capabilities.The 683PSB202K2H uses a Low Dielectric Constant (LDC) film for achieving high performance. The film has high resistivity and reliability. The capacitor’s construction can be divided into three sections: the dielectric layer, the cathode, and the anode. The dielectric layer is made of a uniform thickness of the Low Dielectric Constant material. It stores the energy when a voltage is applied. The cathode and anode comprise the two terminals which provide electrical connection from the outside world. When a voltage is applied across the two terminals, electric current will flow through the two layers of the dielectric. This current will create a storage of electrical charge in the capacitor, which is used to produce a capacitance.

The capacitance of the 683PSB202K2H depends on the dielectric material used, the thickness of the dielectric layer, the size of the electrodes, and the applied voltage. In addition to the characteristics of the film material, the capacitor also needs a conductive environment to ensure the maximum performance. This environment is provided by applying a conductive coating on the electrodes as well as the dielectric layer. This conductive coating also helps to increase the capacitance, reduce the ESR, and reduce the dissipation factor.

The 683PSB202K2H films are suitable for operation up to DC at high temperature. The capacitor offers low ESR and ESL, excellent temperature and voltage stability, and high thermal endurance. This makes it ideal for power supply applications in industrial, automotive, consumer, and audio products. Some of the applications of the capacitor include motor drive, server, synchronous rectifier, welding inverters, lighting systems, and automotive DC-DC converters.

In conclusion, the 683PSB202K2H is a reliable and high-performance film capacitor suitable for use in power supply applications. It offers features such as low ESR, low ESL, high ripple current capabilities, voltage and temperature stability, and high thermal endurance. The wide range of applications makes it an ideal choice for various industries.
