Film capacitor types. As their name suggests, film capacitors employ a plastic film as dielectric. The technical ancestor of this type of capacitor is the paper capacitor invented in the second half of the 19th century. It consisted of paper impregnated with oil or paraffin, sandwiched between sheets of aluminum foil and rolled into a round shape. A capacitor where the metal foil is
By radiation RFI suppression capacitors are the most effective way to reduce RF energy interference. As its impedance decrease with frequency, it acts as a short-circuit for high-frequencies between the mains terminals and/or between the mains terminals and the ground.
Film capacitors are build up by two electrodes (the capacitor plates) with plastic dielectric

RP is a magnitude defined in DC (insulation resistance). Capacitance is the amount of electrically charged carriers a capacitor can store per unit of volt-age. The rated capacitance CR of a capacitor is the value for which it is designed, and that is in-dicated on it. Capacitance is measured under standard conditions to IEC 60068-1:2013.

Film capacitors are made out of two pieces of plastic film covered with metallic electrodes, wound into a cylindrical shaped winding, with terminals attached, and then encapsulated. In general, film capacitors are not polarized, so the two terminals are interchangeable. There are two different types of plastic film capacitors, made with two different electrode configurations:

The demand for inverters used in environment-related equipment such as EVs/HEVs and solar/wind power generation systems is expanding in the capacitor market. For such applications requiring enduring high voltage exceeding 500 VDC and long-term use for several tens of years along with a high level of safety, demand for film capacitors is increasing.
Film Capacitors are available at Mouser Electronics from industry leading manufacturers. Mouser is an authorized distributor for many film capacitor manufacturers including Cornell Dubilier, KEMET, KYOCERA AVX, Panasonic, TDK, Vishay, WIMA & more. Please view our selection of film capacitors below.

The lowest frequency at which the impedance of the capacitor is a minimum when applying a sinusoidal voltage. The ambient free air temperature is the temperature of the air surrounding the component. The climatic category code (e.g. 50 / 100 / 56) indicates to which climatic category a film capacitor type belongs.
Vishay film capacitors uses the following film materials in their production: Polyester film offers a high dielectric constant, and a high dielectric strength. It has further excellent self-healing properties and good temperature stability. The temperature coefficient of the material is positive.
On Segmented Film Technology Capacitors, the self healing effect is more controlled. The film metalization is made by forming a pattern of segments, which are connected to each other by micro fuses. This limits the healing current and limits the self-healing effect to a well defined section of the film.
The most important reliability feature of film capacitors is their self-healing capability, i.e. their abil-ity to clear faults (such as pores or impurities in the film) under the influence of a voltage. The metal coatings, vacuum-deposited directly onto the plastic film, are only 20 50 nm thick.
For the life of a film capacitor, the Mean Time To Failure(MTTF), which is calculated by the inverse of the failure rate, is used as the basis for the life calculation. If a capacitor is used at high temperatures, its service life will be shortened due to thermal deterioration.
