6 FAQs about [Mbabane Film Capacitor Production]

What is a plastic film capacitor?

Plastic film capacitors are also the oldest dielectric used in capacitor construction, as plastic film capacitors were the primary power factor correction design for the original electrical grids and were in mass production as far back as 1901.

How reliable are film capacitors?

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.

What determines the self-inductance of a film capacitor?

The self-inductance or series inductance LS of a film capacitor is due to the magnetic field created by the current in the film metallization and the connections. It is thus determined by the winding structure, the geometric design and the length and thickness of the contact paths.

What are the raw materials for capacitor films?

The preferred choice of raw materials for capacitor films are polypropylene (PP) and polyethylene terephthalate (PET). PP is independent of frequency and temperature (<105°C) and has a high impulse stability – therefore it can be used in AC and DC applications.

How do you calculate the life of a film capacitor?

For the life of a film capacitor, the Mean Time To Failure(MTTF), which is calculated by the inverse of the failure rate, is used as the basis for the life calculation. If a capacitor is used at high temperatures, its service life will be shortened due to thermal deterioration.

How does film shrinkage affect a capacitor?

Additional changes in the capacitor dimensions will follow as a consequence of film shrinkage. The absorption of moisture increases the number of permanent dipoles inside the capacitor, pro-ducing reversible effects on capacitance, dissipation factor and insulation resistance, which are treated in the respective sections.
