In this standard, the electrical characteristics of capacitors are described by an idealized series-equivalent circuit with electrical components which model all ohmic losses, capacitive and inductive parameters of a film capacitor:
The inherent geometry of film capacitor structure results in very low ohmic losses and a very low parasitic inductance, which makes them especially suitable for applications with very high surge currents (snubbers) and for AC power applications, or for applications at higher frequencies.

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.
A capacitor's ability to withstand vibration (e.g. as occurs in applications involving rotating machin-ery), is tested to IEC60068-2-6:2007. EPCOS offers film capacitors especially designed for operation under more severe vibration regimes, such as those found in automotive applications. Further information available upon re-quest.
The design of a structural capacitor should include consideration of the capacitance of the interface between the dielectric film and electrode. The design should also address the electrical contacts on the structural capacitor.
