Introduction of C4AEJBU5125A12J Capacitor

Film capacitors, also known as film dielectric capacitors, are a capacitor type that uses a film as the dielectric. Specifically, the dielectric can be a polyester material, metalized polypropylene film, metalized polyethylene naphthalate, or polyphenylene sulfide. Film capacitors are used in applications involving higher voltages, higher currents, and more demanding temperatures. C4AEJBU5125A12J is a kind of film capacitor which has a wide range of applications and operates based on certain principles.

Mode of Operation

C4AEJBU5125A12J capacitors operate based on the principles of electrostatics. When a voltage is applied to two surfaces, they become polarized due to the potential difference, resulting in the separation of charge. This separation of charge creates an electric field that stores energy, and this electric field is what provides the capacitance of the capacitor. The C4AEJBU5125A12J capacitor is a two-element capacitor with an electrical grade polyester film acting as the dielectric. The film is held between two metal electrodes, and is etched to create a series of inter-connected dielectric layers. When voltage is applied to the capacitor, the electrical field between the two electrodes attracts and repels electrons, resulting in the stored energy.

Applications of C4AEJBU5125A12J Capacitor

C4AEJBU5125A12J capacitors are used in a wide range of applications, including:

• Audio and video equipment
• Power supplies
