The following are some generalities, not hard rules... When using a capacitor in an analog signal path, the type of capacitor is more critical, because the downsides of some types of capacitors can influence the analog signal. For these circuits, you want to steer yourself towards using better capacitors, and away from using the worst capacitors.

Film capacitors, plastic film capacitors, film dielectric capacitors, or polymer film capacitors, generically called film caps as well as power film capacitors, are electrical capacitors with an insulating plastic film as the dielectric, sometimes combined with paper as carrier of the electrodes. The dielectric films, depending on the desired dielectric strength, are drawn i

The capacitor''s electrode system is an important design consideration. There are three basic options for electrodes used with polypropylene capacitors. A description of each follows: Metallized Capacitors --- Metallized Film --- Metallized Film Metallized capacitors use a thin layer of vapor deposited
Film capacitors are capacitors which use a thin plastic film as the dielectric. This film is made extremely thin using a sophisticated film drawing process. Once the film is manufactured, it may be metallized or left untreated, depending on the needed properties of the capacitor.
Metallized paper capacitor In metalized paper capacitor, the paper is coated with a thin layer of zinc or aluminum and rotated in the form of a cylinder. The entire
Some polypropylene metallized film capacitors are specially designed for direct mounting on IGBT modules. A hybrid electrode capacitor is a combination of metallized electrode and discrete foil technologies. These
Metallized capacitor films feature a thin metal layer deposited on one or both sides of the dielectric film. In the event of a localized dielectric breakdown, the metal layer around the fault site will vaporize, isolating the defect and preventing the capacitor from failing completely. This self-healing property enhances the reliability and
MKP is the abbreviation of metallized polypropylene film capacitor in Germany. In China factories, some of them call WEET WME Premium Music Cap as MPT, M is for metallized, P is for polypropylene and T is for Shape tube. Just some

A ceramic capacitor is a non-polarized fixed capacitor made out of two or more alternating layers of ceramic and metal in which the ceramic material acts as the dielectric and the metal acts as the electrodes. The ceramic material is a mixture of finely ground granules of paraelectric or ferroelectric materials, modified by mixed oxides that are necessary to achieve the capacitor''s desired characte

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.

Electrodes are then added and the assembly is mounted into a case which protects it from environmental factors. They are used in many applications because of their stability, low inductance and low cost. There are many types of film capacitors, including polyester film, metallized film, polypropylene film, PTFE film and polystyrene film.
Metallized film capacitors are significantly smaller in size than film/foil versions and have self-healing properties. Thin metallized electrodes limit the maximum current carrying capability respectively the maximum possible pulse voltage. Film/foil film capacitors have the highest surge ratings/pulse voltage, respectively.
Hence, as a rule, metallized film capacitors should serve well in service for long time, and self-healing incidents in service are very occasional. General construction of metallized film capacitor is as below. Self-healing rectifies any defective spots during the manufacturing process of capacitors.
Thin metallized electrodes limit the maximum current carrying capability respectively the maximum possible pulse voltage. Film/foil film capacitors have the highest surge ratings/pulse voltage, respectively. Peak currents are higher than for metallized types. No self-healing properties: internal short may be disabling.
