What are film capacitors used for?
Film capacitors are widely used in power electronics applications including but not limited to DC Link, DC output fltering, and as IGBT snubbers.
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.
What is the dissipation factor of film/foil capacitors?
The dissipation factor for film/foil capacitors is lower than for metallized film capacitors, due to lower contact resistance to the foil electrode compared to the metallized film electrode. The dissipation factor of film capacitors is frequency-, temperature- and time-dependent.
How is the finish of film capacitors assessed?
The finish of film capacitors is assessed in compliance with EPCOS finish specifications. For more detailed specification, refer to the "General technical information" chapter. When applicable, the individual data sheets are definitive for finishing. The failure rate is defined as the failure percentage divided by a specified operating period.
