BFC237535202 application field and working principle

Film capacitors are an important subset of capacitors, highly valued for their combination of superior performance characteristics, reliability, high breakdown voltages and low dissipation factor. Film capacitors use thin or thick layers of dielectric material in order to produce electrodes, becoming the nucleus of the capacitor’s construction. In this type of capacitors, the insulating material is usually plastic or metalized film. Such materials have a high dielectric strength and low loss, allowing manufacturers to build capacitors of smaller size and higher capacitance ratings.The BFC237535202 is a film type capacitor which is mainly employed as filtering and smoothing in rectifier circuits and switching power supplies. It features a dielectric insulation of polyester film, it provides excellent mechanical properties, stability and high temperature endurance. Its casing is made of metalizing film and its lead wire is welded with epoxy resin. This item can endure a maximum operating temperature of 105℃ and features an accuracy of ±10% at 25℃.Understanding the working principle of the BFC237535202 is essential in comprehending its capabilities. The BFC237535202 is an electronic component that stores electrical energy, storing it in an electric field, thus allowing the capacitor to act as a passive circuit component. The capacitor can hold a charge for a certain amount of time, so it can be employed in circuits to block a direct current (DC) and pass an alternating current (AC). The BFC237535202 takes advantage of the so-called electrostatic effect, involving the force between 2 electrically charged objects. A current-carrying conductor will create an electromagnetic field that increases the area’s electric field strength. Connecting a dielectric material between 2 plates of a capacitor, an electric field will be created, attracting and repelling charges, thus accumulating energy in the form of electrical charge. This type of capacitor employs a single layer of metalized plastic, with its top layer used as the positive terminal and the bottom layer, as the negative terminal. When an alternating current flows through the dielectric layer, it causes the electric field lines to move and a capacitive reactance, impeding the flow of current, is created.Film capacitors, such as the BFC237535202, are highly valued for their combination of superior performance characteristics, reliability, high breakdown voltages and low dissipation factor. Furthermore, being able to withstand a high temperature, they are perfect for high-temperature applications, where their insulation, temperature stability and long life are exceptionally important. This type of capacitors is great at smoothing and filtering, making it perfect inclusion in the majority electronic circuits.
