Film capacitors are essential electrostatic capacitors suitable for medium, higher voltage and higher current circuits. Unlike most other dielectric systems, film capacitors feature low loss factor at very low temperature.
The capacitor is a device (part) that performs this charging and discharging of accumulated charges as its function. εr : Relative Permittivity 2. Types of (fixed) capacitors 3. Types of Film Capacitors “Miler” ( Du-Pont) is famous.
Nowadays, however, plastic film capacitors (MK) are brought on the market with metallization alloys based on the advantageous characteristics of zinc but without its tendency towards aqueous corrosion.
The polyester film is most reliable and together with PP most used of the plastic films. It can be produced in thicknesses down to 0.7 μm (0.03 mils). Its tensional stability is high and its ε r ≈ 3.2. This has facilitated manufacture of one for organic dielectrics very space-saving capacitor.
The most common dielectric materials used in the construction of plastic film capacitors are polypropylene and polyester.
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.
The pulse handling capabilities of stacked-film capacitors are of a particular advantage. Each individual layer acts as a single capacitor of small capacitance, so any damage to the contacts due to overloading is restricted to the layers concerned, which might get disconnected.
Film capacitors are essential electrostatic capacitors suitable for medium, higher voltage and higher current circuits. Unlike most other dielectric systems, film capacitors feature low loss factor at very low temperature.
EPCOS FK capacitors are produced using either winding methods or stacking methods. In the conventional production process, capacitors are made by individually rolling the metallized films or the film/foils into cylindrical rolls and then covering them with an insulating sleeve or coat-ing.
