6 FAQs about [Film capacitor slitting worker]
Can film capacitors be produced as wound or stacked foil capacitors?
Film capacitors can be produced as wound or stacked foil capacitors types depending to the final application requirements and features – see figures bellow.
What is a metallized film capacitor?
Metallized film capacitors today are primarily based on aluminum and zinc. Aluminum is particularly suitable for robust designs and high Ohm metallizations due to its environmental stability. Aluminum layers can, for example, be metallized as low as 200 Ohm/sq. on polypropylene film.
What is a pro slitter?
ProSlitter marks the new era of highly efficient slitting machines for commodity films. The ProSlitter unites the many decades of slitting expertise of Kampf and Atlas. The ProSlitter SilverLine is the efficient slitter for cast, blown and calendered primary films and the ideal secondary slitter for biax films. Designed for productivity.
How to test a film capacitor?
For lowest production costs some film capacitors can be used “naked”, without further coating of the winding. Electrical final test — All capacitors (100%) should be tested for the most important electrical parameters, capacitance (C), dissipation factor (tan δ) and impedance (Z).
What is a segmented capacitor film?
Capacitor films where the metallized plane is divided by lines and structures are known as segmented or safety films. These patterns are achieved by an oil masking system during the metallization process. At Steinerfilm, segmented patterns are designed according to the technical requirements of the customer.
What is the minimum rated voltage of film capacitors?
Minimum rated voltage of film capacitors is mostly limited by its mechanical strength to withstand the winding process and it starts typically from >3um per layer corresponding to ~30V, thus it is not direct competition to low voltage SMD other capacitor technologies.
