Lifetime Estimation of Capacitors (Electrolytic, Film Capacitors
When capacitors are used at high voltages, the dielectric is subjected to high voltage stresses, resulting in shortened capacitor''s lifetime. Applying a voltage that is sufficiently marginal to the rated voltage reduces the voltage stress on the dielectric and promotes healing of defective parts of the dielectric *16, which may significantly extend the capacitor''s lifetime.
