Film capacitors are developed from paper capacitors. Specifically, when insulating films of various characteristics such as polyester film and polypropylene film are used as a medium of insulation instead of paper, they are referred to as film capacitors. BFC238301154 is a type of film capacitor.

Application field

Film capacitors have superior electrical characteristics compared to paper capacitors, and have excellent performance such as heat resistance, electric strength, insulation, and self-healing effect. Therefore, they are often used in various high frequency electronic applications such as liquid crystal display BL (back light) power modules, radio frequency (RF) selectors, inverters, switching power supplies, and household electrical appliances. BFC238301154, as a type of film capacitor, is mainly used in automotive electronics, digital cameras, and portable saws. Its high capacitance\'senables greater stability when used in automotive mechanical equipment. Moreover, due to its large capacitance, higher ripple ratings, low profile, and long working life, BFC238301154 is increasingly used in digital cameras for reducing the occurrence of noise pictures. It is also used in portable saws as its lower equivalent series resistance (ESR) guarantees higher power and less heat generation.

Working Principle

BFC238301154 works by creating an electrostatic field between two conductors, usually the metal plates or electrodes, separated by a dielectric material. The capacitor is wired such that one of the plates or electrodes is connected to the positive terminal and the other electrode is connected to the negative terminal. When an electric current is applied to the terminals, charge is created on both plates which generates an electric field between them. As the electric field\'s strength increases, the voltage between the plates increases. When the voltage reaches a certain level, the capacitor counteracts the current flow by increasing its capacitance. This produces an effect known as dielectric absorption in which the spacing between the plates narrows allowing the electrical current to enter the dielectric material. The absorbed current produces an electrostatic field, which counteracts the voltage applied to the terminals.

This is the basic working principle of the BFC238301154. Its dielectric material can provide excellent performance such as heat resistance and electric strength, achieving high capacitance, long working life and low equivalent series resistance (ESR).
