Film capacitors are passive components that use an extremely thin plastic film as a dielectric insulator. They are constructed of two pieces of plastic film wound into a cylindrical shape. The winding is attached to two unpolarized terminals, which represent the plates of a basic capacitor, and is then encapsulated for protection.
Customer ServiceThis is the main benefit of metallized film capacitor. The area thus isolated during self-healing incident is so miniscule that capacitor value is practically unaffected. For good clearing and evaporation of metal, sufficient energy must be available at the point of fault, and during the process of clearing, there is a small dip in voltage (in micro volts) across capacitor

A comparison chart of various film capacitors is shown in Table 1.
The performance of film capacitors differs, depending on the type of dielectric. It is therefore necessary to select the proper type according to the usage conditions. Wound type film capacitors with internal electrodes are made of metal foil (aluminum, tin, copper, etc.) sandwiched between plastic film layers and rolled up.
They are constructed of two pieces of plastic film wound into a cylindrical shape. The winding is attached to two unpolarized terminals, which represent the plates of a basic capacitor, and is then encapsulated for protection. Film capacitor manufacturing.

Read on to know more about a film capacitor: what is film capacitor, how it is made and what makes it so popular among its kind.
Film capacitors are found for example in electric home appliances, electronic circuits in cars, industrial equipment, and power electronics devices. Depending on how the internal electrode is formed, film capacitors are divided into two main categories, namely foil electrode types and vapor deposition electrode (metallized film) types.
The actual capacitance of film capacitors depends on the measuring frequency and the ambient temperature. Standardized conditions for film capacitors are a measuring frequency of 1 kHz and a temperature of 20 °C. The percentage of allowed deviation of the capacitance from the rated value is called capacitance tolerance.
