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.
film capacitors satisfy a large variety of elec-tronic applications, because available dielectrics have excellent fundamental electrical characteris-tics, high stability and longevity. Capacitor manufacturers are constantly improving the breed to deliver greater capacitance within smaller package dimensions.
The taping information is based on the international standard IEC 60286-2. Remark valid for all taped film capacitors, axial and radial, ammo and reel: for all taped film capacitors a maximum of 3 slices per 1000 pieces is permitted. 1.1. RADIAL POTTED FILM CAPACITORS (Dimensions in mm) 1.1.1.

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.
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.
