Film Capacitors

Film capacitors, or plastic film capacitors, use plastic film as the material for the dielectric. These capacitors are polarized capacitors with inherent advantages in miniaturization and are also constructed using a layer of polymer films, such as polyester and polypropylene, as a dielectric. Film capacitors are distinguished from other types of capacitors mainly by their construction method. They can be divided into two general categories: film dielectric capacitors and foil dielectric capacitors.

BFC237590158 Application Field and Working Principle

BFC237590158 film capacitors are designed for use in AC power and low-voltage DC applications such as power factor correction, power conditioning, voltage regulation, power supply circuits, and transformer power supplies. The BFC237590158 film capacitors are safety-approved and self-healing and feature low ESR, high ripple current capability, low inductance, and excellent electrical performance. These capacitors are capable of withstanding severe environmental conditions and have an operating temperature range of -40°C to +105°C.

The working principle of the BFC237590158 Film Capacitor is based on the aggregation of films, which is achieved by electrically connecting the master roll of film rolls together. When the film rolls connect to each other, a dielectric layer is created. This dielectric layer is used to form a capacitor to store the electrical energy and allow it to flow through a specific channel. This flow is regulated and monitored via a small metal core that serves as an insulation between the two sheets of films. The stored energy is released as a current when the capacitor is energized by an electrical signal.

The BFC237590158 capacitor is highly efficient and can be used in a variety of applications. It has a low parasitic loss and can operate up to -55°C. Its slim and compact design makes it easy to install in tight spaces. The construction of the film capacitor also makes it resistant to vibrations and shocks. Additionally, the capacitor comes with a low dissipation factor and an excellent temperature coefficient. All of these features combine to ensure the longest life span for the capacitor.
