6 FAQs about [Metalized Film Capacitor Dielectric]
How can metallized film capacitors be optimized for specific applications?
Capacitor manufacturers can optimize the characteris-tics of metallized film capacitors for specific applications by selecting a suitable dielectric. For example, polyester films display good properties for general-purpose applications.
Do metallized film capacitors have a low dielectric constant?
At present, metallized film capacitors mainly use biaxially oriented polypropylene films (BOPP), which have high breakdown strength (~600 kV/mm) and low dielectric loss (~0.0001) . However, polypropylene’s low dielectric constant (2.2) limits the capacitance of film capacitors and the miniaturization of their devices.
Can polypropylene film reduce the volume of metallized film capacitors?
For this reason, this paper considers reducing the volume of metallized film capacitors by increasing the dielectric constant of polypropylene film and analyzes a feasible range for the increased dielectric constant. Through the Comsol finite element simulation calculation, it is found that the volume can be reduced by 26.7%.
What are plastic film capacitors?
Plastic film capacitors are generally subdivided into film/foil capacitors and metalized film capacitors. Film / foil capacitors basically consist of two metal foil electrodes that are separated by an insulating plastic film also called dielectric. The terminals are connected to the end-faces of the electrodes by means of welding or soldering.
