Power Film Capacitor Application Guide
Film capacitors are widely used in power electronics applications including but not limited to DC Link, DC output fltering, and as IGBT snubbers.
Ferrite core
In electronics, a ferrite core is a type of magnetic core made of ferrite on which the windings of electric transformers and other wound components such as inductors are formed. It is used for its properties of high magnetic permeability coupled with low electrical conductivity (which helps prevent eddy currents). Moreover, because of its comparatively low losses at high frequencies,
Characteristics and Definitions Used for Film Capacitors
Film capacitors are build up by two electrodes (the capacitor plates) with plastic dielectric material in between. The type of electrode used determines whether the capacitor is a metalized film or film / foil type. In metalized types, the very thin electrode is

6 FAQs about [Function of film capacitor rod core]
What is a film capacitor?
Film Capacitor is one of the most popular and widely used capacitors. These possess a difference in their properties of dielectric. In the modern type of film capacitor, there is the ‘direct electrical connection’ establishment with the electrodes that are present on both the windings. This keeps the path of the current to the electrode very short.
What are the dielectric characteristics of a film capacitor?
The dielectric characteristics of the film capacitor are different. The dielectric used in this sort of capacitor can be any form of film. There is a ‘direct electrical connection’ establishment with the electrodes that are present on both windings in the modern form of film capacitor. This reduces the current’s route to the electrode to a minimum.
What are the advantages of a film capacitor?
In the modern type of film capacitor, there is the ‘direct electrical connection’ establishment with the electrodes that are present on both the windings. This keeps the path of the current to the electrode very short. This capacitor has various benefits it has very low ESR (ohmic resistance) and ESL (Parasitic Inductance).
How are AC film capacitors selected?
Dielectric, electrodes and encapsulation systems are selected to achieve the best performance based on the voltage waveform, current and other environmental parameters. AC film capacitors are typically packaged in metal cans, filled or vacuum impregnated with oil to reduce the occurrence of corona discharge.
How does a DC film capacitor work?
DC 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. Leads are attached at both ends prior to being assembled into the desired package.
Why are power capacitors different from film capacitors?
Although the materials and the construction of power capacitors are mostly similar to the smaller film capacitors, they are specified and marketed differently for historical reasons. The "film capacitors" were developed together with the growing market of broadcast and electronic equipment technology in the mid-20th century.
