Film Capacitors

Film capacitors, also known as polymer film capacitors or plastic film capacitors, are one of the main categories of modern electric double layer capacitors. They are mainly composed of polymer film dielectric and a pair of electrodes. Most of the conventional film capacitors use polyethylene terephthalate (PET), polyester film as the dielectric, and aluminum foil, bronze foil, and copper foil as the electrode material.

FFB54D0117KJC application field and working principle

The FFB54D0117KJC is a type of film capacitor with stable performance, which is widely used in the digital, communication, and industrial control system. It has the characteristics of high frequency stability, high temperature resistance, high reliability, small size, and light weight. The capacitance of the FFB54D0117KJC has a wide range from 0.1uF to 330uF, and its rated voltage ranges from 100 to 630 Vdc. The FFB54D0117KJC provides an ideal solution for limiting, decoupling, noise suppression, protection and buffering in the field of industrial, automation, lighting, and communication.

The working principle of FFB54D0117KJC is quite simple. It converts electric energy into electrostatic energy and can store this electrical energy. When a voltage is applied across its two electrodes, the capacitor will charge up and produce an electric field in the dielectric. This electric field produces parallel plates of opposite polarity. The Charge that accumulates in each plate is equal but opposite, so the net charge stored in the plates is zero. When a voltage is applied across the capacitor, free electrons accumulate on one plate and leave the other plate, resulting in a net positive charge accumulation on one plate, and a net negative charge accumulation on the other.

In the FFB54D0117KJC, the parallel metal plates are held apart by the dielectric material, usually polyester film or polypropylene film. The dielectric acts as an insulator, so the current follows the path of least resistance and is not allowed to pass through the capacitor. The capacitance of FFB54D0117KJC is determined by the size and material of the plates, as well as the type of dielectric material between them. The material of the plates determines how much charge can be stored, while the dielectric material determines how quickly the charge can be released.

The FFB54D0117KJC has high reliability and excellent temperature range, making it ideal for use in industrial settings and electronic equipment. It is also resistant to moisture, making it useful in humid environments. With its small size, high capacity, and wide range of usage, the FFB54D0117KJC is becoming increasingly popular in the modern market.
