Film capacitors are polar capacitors constructed of thin plastic film dielectric material. The material imparts stability and good electrical properties to the capacitor. A metal layer is deposited on the surface of the film dielectric material providing the plates or electrodes needed in the capacitor construction. The material used in the metal layer varies depending on the needed application. The capacitors may be further enclosed and sealed against weathering, or moisture, in some cases over the film layer.

The BFC246729392 film capacitor is an encapsulated metalized polyethylene film capacitor with polypropylene dielectric. It has an axial leaded terminal and is designed for any type of electrical equipment operating at comparatively higher frequency. The BFC246729392 can be used in applications such as AC capacitors, DC capacitors, Snubber capacitors, DC filter capacitors, Pulse-Hilger capacitors, DC link capacitors, HVDC filter systems, high voltage circuit breakers and transients in switch modes power supplies, as well as many other applications.

The working principle of a film capacitor is quite straightforward when voltage is applied across two electrical plates, the distance between them determines how much energy can be stored in the capacitor. The more layers between the plates, the less current will flow and the more energy will be stored. Due to the low dielectric constant of the plastic film, the layers between the plates are much thinner than those of a ceramic capacitor, increasing the amount of energy stored in the film capacitor at the same voltage.

Additionally, film capacitors have high temperature stability, low ESR and ESR variation, low self-heating, and a high ripple handling capacity. Films also have very low dielectric absorption which prevents transient voltage from affecting the capacitor, allowing only low voltage to be charged. Thus, they are well suited for applications where precision and stability in electrical properties is necessary.
