Film Capacitors

A film capacitor is a type of capacitor that takes advantage of a thin plastic film as the medium for its dielectric layer. It is also sometimes referred to as a plastic film capacitor because the primary component that gives it its capacitance properties is usually a plastic film, such as polystyrene, polypropylene, polyethylene, and polycarbonate.

B32522C0335K289 application field and working principle

The B32522C0335K289 is a polypropylene film capacitor which offers high reliability and reliability with its operating temperature range up to 105°C. The B32522C0335K289 is mainly used in power supplies, UPS, AC/DC motor drive, switching power supplies, and other general purpose applications.

The B32522C0335K289 film capacitor utilizes metalized polypropylene film as the dielectric material. This type of film provides very good high temperature resistance and stability characteristics. The metalized, or metallized, layers are made up of an alternate layer of metal and coating that are deposited on two sides of the foils. The metal side serves as the electrical connection between the two plates of the capacitor, while the coating helps to ensure a stable electrical connection. The alternating metal and coated layers are connected together creating an electrical “bridge” across the two plates. This allows the capacitor to store charge and discharge current as needed.

The B32522C0335K289 also features very low ESL and ESR. This ensures very low EMI radiation, which makes the B32522C0335K289 particularly suitable for applications where high EMI radiance is not desired. Its low profile also makes it suitable for use in many slim design applications. The B32522C0335K289 is rated for an extended life up to 2,000 hours at 105°C and up to 3,000 hours at 85°C.

The B32522C0335K289 also features full safety regulations in order to ensure a safe use, which is especially important in applications such as medical and energy saving applications. It also has a very low impedance across the full temperature range ensuring a stable performance in high temperature and voltage applications.

Overall, the B32522C0335K289 is an excellent film capacitor, possessing excellent high temperature and high EMI protection, and suitable for use in many general purpose, power related, and even medical applications.
