Film Capacitors

Film capacitors, also known as plastic film capacitors, are capacitors consisting of a thin plastic film as a dielectric and two metal foil electrodes. These capacitors may use a plastic film like polyethylene terephthalate (PET) or polyphenylene sulfide (PPS). They are typically surface-mount, which makes them suitable for high-density circuit designs.

The BFC233614223 series of capacitors are polyethylene terephthalate, metallized film capacitors with a curved profile for higher correction properties than similarly sized straight-profile capacitors. These capacitors have a high performance-to-size ratio and are excellent at high pulse power applications.

Application Field

The BFC233614223 series of capacitors are most suitable for applications where there is space constraints such as cell phones, GPRS communication modules, tuning power supplies, power supplies for mobile devices, data communication devices and gaming consoles. Due to its high capacitance values, the capacitors are also well-suited for automotive electronics, home audio, consumer audio, and medical electronics. The capacitance values range from 100nF to 4000nF and are available in 5mm to 20mm packages sizes

Working Principle

The working principle of the BFC233614223 film capacitor is simple. It consists of a thin plastic film dielectric which is coated on both sides with a metal or metallized substance. These metals are, in most cases, aluminum, zinc, and lead. When an electric field is applied, the metal coatings attract and repel the charges from each other, creating a capacitance across the film. By varying the thickness and size of the film or varying the metal coatings, the capacitance can be modified.

The BFC233614223 series of capacitors offer high performance at a fraction of the size of traditional capacitors. These capacitors are well-suited for applications where space is limited and high performance is required for products or applications that require high efficiency, high current capacity, and high speed performance.
