Metallized film capacitors used for EMI filtering: A reliability review
Film capacitors are generally subdivided into film/foil capacitors and metallized film capacitors. Film/foil capacitors consist of alternating layers of polymer or paper film and metal foil that are wound together. The foils are typically on the order of 6 μm in thickness, giving them higher current handling capabilities than a similarly sized metallized film capacitor

6 FAQs about [Proportion of Metal Film Capacitors]
How do metalized film capacitors work?
The electrodes of metalized film capacitors consist of an extremely thin metal layer (0.02 μm to 0.1 μm) that is vacuum deposited either onto the dielectric film or onto a carrier film. The opposing and extended metalized film layers of the wound capacitor element are connected to one another by flame spraying different metals to the end-faces.

Compared to making the capacitor with sep-arate foil and film sheets, met-allizing enables smaller size, lighter weight, lower cost per microfarad and self-healing, but it also
What are plastic film capacitors?
Plastic film capacitors are generally subdivided into film/foil capacitors and metalized film capacitors. Film / foil capacitors basically consist of two metal foil electrodes that are separated by an insulating plastic film also called dielectric. The terminals are connected to the end-faces of the electrodes by means of welding or soldering.
How reliable are film capacitors?
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.
What happens if a metallized film capacitor is over withstand voltage?
*) In case of the metallized film capacitors (evaporated metal electrode type), if voltage in excess of the withstand voltage (or apparently in excess of the withstand voltage due to the lowering of withstand voltage) is applied, self-healing will happen continuously.
What is a metallized capacitor?
An M ( metallization) is prefixed to the short identification code of capacitors with metallized films. *) MFP and MFT capacitors are constructed using a combination of metal foils and metallized plastic films. They are not covered by DIN EN 60062:2005. The following table is a summary of important technical data.
