KEMET Evox Rifa PME295 metallized paper capacitor feature a high dielectric constant with excellent self-healing properties and transient handling capabilities.  KEMET Evox Rifa metallized paper capacitors develop a high ionization level due to the impregnated dielectric material and maintain outstanding reliability in mains connected and other low frequency applications.  KEMET Evox PME295 capacitors are constructed of a multi-layer metallized paper dielectric encapsulated and impregnated in self-extinguishing material meeting the requirements of UL94V-O.  Typical applications of the KEMET Evox Rifa PME295 capacitors are interference suppressors.

KEMET Evox Rifa PME295 metallized paper capacitors are classified as both Y1 capacitors. Y1 capacitors are used in positions where a failure of the capacitor could expose somebody to danger of electric shock and uses double insulation or reinforced insulation. KEMET Evox Rifa PME295 capacitors meet the most stringent IEC humidity class, 56 days; while maintaining the highest possible safety regarding active and passive flammability.

Self Healing of KEMET Evox Rifa Impregnated Paper Capacitors
If a conducting particle or a voltage surge punctures the dielectric, an arc occurs at the point of failure melting the surrounding metal and insulating the area of the breakdown. In the metallized paper capacitor as processed by KEMET Evox Rifa a breakdown caused by a short transient normally results in an improvement of the insulation resistance. KEMET Evox Rifa metallized paper capacitors are to be preferred if the capacitor is to be used where uncontrolled transient voltages can occur.
