Film Capacitors: BFC233848023 Application Field and Working Principle

Film capacitors are a type of capacitor which consist of a dielectric film made of one or more layers. The film is usually constructed from polyethylene terephthalate, also known as polyester. They may also be made from polypropylene or other specialty plastics. It is filled with electrolytic solution or air gap depending on the application.

The BFC233848023 is a film capacitor specifically designed for general purpose filtering and driver applications. It is designed using high quality materials to last through rigorous use and harsh environmental conditions. Its construction is composed of a polypropylene film dielectric, tinned copper leads and terminals and a proprietary coating which ensures long-term reliability. Its unique construction also allows it to offer superior performance in several applications.

The application field of BFC233848023 film capacitor covers mostly automotive, industrial, commercial and medical areas, with ultra low ESL, superior humidity resistance, and stable temperature performance, and EMI protection capability. It is especially suitable for usage in automotive applications, acting as a filter capacitor for power supply or noise signal suppression.

The working principle of the BFC233848023 film capacitor is similar to most types of electrolitic capacitors. The capacitance of the device lies in the dielectric film which is placed between two metal electrodes. The film is a substance which is highly resistive to electric current, and as it is sandwiched between the metal electrodes, the two are separated from each other, allowing one to become positively charged and the other to become negatively charged.

When a voltage is applied to the capacitor, electrons begins to move across the dielectric material, charging it as they do so. The more voltage that is applied, the more charge the material accumulates and the higher its capacitance will become. This phenomenon is known as electric polarization and is a necessary part of the working principle of a film capacitor. This charge can then be discharged when a reverse voltage is applied.

The BFC233848023 film capacitor is designed to provide superior performance in a range of applications due to its unique construction and materials. It has been specifically designed to last through years of opeartion and to handle high environmental levels. The device provides an excellent solution for automotive applications, industrial systems, commercial electronics and medical equipment.
