6 FAQs about [Capacitor gold film production process]
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 metallized capacitor?
An M ( metallization) is prefixed to the short identification code of capacitors with metallized films. *) MFP and MFT capacitors are constructed using a combination of metal foils and metallized plastic films. They are not covered by DIN EN 60062:2005. The following table is a summary of important technical data.
How are Epcos FK capacitors made?
