Film capacitors are versatile components that can be designed into power electronics for industries ranging from consumer and renewables to automotive, aerospace and military. These capacitors come with very specific advantages including non-polarity, a high insulation resistance, low dielectric losses and self-healing capability.
Its structure is made of “Plastic Films.” These films are made to be very thin. Once the “Film drawing procedure” is done, the created film can be coated with a metal or left as is, depending on the use. The generic method of development for these capacitors begins with the removal of a thin layer of plastic film.
While ceramic capacitors offer better dv/dt capabilities, film capacitors are good (with a maximum value of 2200 V/µs) making them suited for use in snubber circuits. Film capacitors also have low equivalent series resistance (ESR), low equivalent self-inductance (ESL) and can tolerate large peak currents.
The use of this capacitor reduces losses even on transmissions with high frequencies. Its structure is made of “Plastic Films.” These films are made to be very thin. Once the “Film drawing procedure” is done, the created film can be coated with a metal or left as is, depending on the use.
Very high current film capacitor types generally use thicker aluminum foil electrodes. ▶Film capacitors are generally wound in a stagger, with opposing electrodes extended out at each end. ▶Ends of the windings are typically sprayed with a fine zinc spray to connect the turns at each end.
As the name suggests, the film/foil capacitor uses plastic films as dielectric and is placed inside two layers of electrodes made of aluminum foil. These interleaved layers are so structured that the metallic layers do not contact with each other. These capacitors can be either inductive or non-inductive.
