The calculation of the lifetime-expectancy of Aluminium Electrolytic Capacitors is commonly made by using the Arrhenius-formula. However, for Film Capacitor it is not in practice to apply such a formula. Most manufacturers of Film Capacitors only provide general curves for the expected lifetime as a function of the temperature and voltage. Furthermore, it is not respected that the lifetime of metallized film capacitors is also influenced by humidity.

The company BM, in collaboration with the Swiss expert for Film Capacitors, Dr. Roland Gallay, can provide the possibility to calculate the expected lifetime of Film Capacitors under the exact application-conditions. In case of interest, please contact us for further information.
