Vishay film capacitors uses the following film materials in their production: Polyester film offers a high dielectric constant, and a high dielectric strength. It has further excellent self-healing properties and good temperature stability. The temperature coefficient of the material is positive.
However, due to the adverse working conditions, such as high voltage and high temperature, film capacitors generally own a lower reliability index. And the sudden failure or fault of film capacitors is very likely to cause the paralysis of the whole electronic system, which may lead to a catastrophic accident.
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.

The accelerated testing is an important method to investigate the reliability performance of DC film capacitors. In , the aging of metallized polymer capacitors has been studied under accelerated testing conditions of voltage and temperature.
In the case of metallized films, this may lead to electrode corrosion when the capacitors are submitted to environmental conditions of high humidity. The electric-field stess in metallized film capacitors may be much larger than in film foil capacitors. This is obtained thanks to the ability of the electrodes to self-heal.
