What are film capacitors?
The "film capacitors" were developed together with the growing market of broadcast and electronic equipment technology in the mid-20th century. These capacitors are standardized under the rules of IEC/EN 60384-1 "Capacitors for use in electronic equipment" and different "film materials" have their own sub standards, the IEC/EN 60384- n series.
How can film capacitors be optimized?
Film capacitors can be optimized through diferent materials and manufacturing methods. Capacitors are all unique; their fundamentals, the manufacturing processes, advantages and even technology trends are worth highlighting. There are diferent grades and applications critical to considering before choosing the best option.
What are the advantages of film capacitors?

What is the capacitance of a plastic film capacitor?
The film/foil variants of plastic film capacitors are especially capable of handling high and very high current surges. Typical capacitance values of smaller film capacitors used in electronics start around 100 picofarads and extend upwards to microfarads.
What is the difference between a film foil capacitor and a metalized capacitor?
The primary distinction between a film foil capacitor and a metalized capacitor is that the metallic electrodes are fused into either side of the dielectric plastic in the latter instead of layering. While it raises the cost and also adds a step to the production process, it has greater reliability and smaller dimensions than a film foil condenser.
