What is the history of film capacitors?
Over the history of film capacitors, from a material perspective, the major breakthrough started with the move from paper to polymers, and especially to polypropylene, which finally became the dominant dielectric in film capacitors today.
How reliable are film capacitors?
The most important reliability feature of film capacitors is their self-healing capability, i.e. their abil-ity to clear faults (such as pores or impurities in the film) under the influence of a voltage. The metal coatings, vacuum-deposited directly onto the plastic film, are only 20 ... 50 nm thick.
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.
What factors affect the failure rate of a film capacitor?
In the case of film capacitors, the two most relevant parameters affecting the failure rate are tem-perature and voltage. In the IEC61709:2011 standard, models for stress factors are consequently applied in order to convert the failure rates under reference conditions to values applying for oper-ating conditions.
Are the dimensional drawings definitive for the finish of film capacitors?
The dimensional drawings in the individual data sheets are definitive for the dimensions. 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.
What determines the self-inductance of a film capacitor?
The self-inductance or series inductance LS of a film capacitor is due to the magnetic field created by the current in the film metallization and the connections. It is thus determined by the winding structure, the geometric design and the length and thickness of the contact paths.
