KEMET PMZ2074 metallized paper capacitor feature a high dielectric constant with excellent self-healing properties and transient handling capabilities.  KEMET 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 PMZ2074 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 PMZ2074 capacitors are interference suppressors in X2 (across-the-line) applications or other demanding application where two capacitors are utilized in series.

KEMET PMZ2074 metallized paper capacitors are classified as both X2 capacitors. KEMET X2 capacitors are used in positions where a failure of the capacitor would not expose anybody to danger of electric shock. KEMET PMZ2074 capacitors meet the most stringent IEC humidity class, 56 days; while maintaining the highest possible safety regarding active and passive flammability.

Corona Resistance of KEMET Impregnated Paper Capacitors

KEMET impregnated capacitors feature a impregnation technique that eliminates pin-holes, thus also eliminating potential gas cells.  This elimination of potential gas cells cannot entirely eliminate the possibility of weak points in the winding.  These could result in a glow discharge, but the occurrence of such a discharge will eliminate the weak points and improve the insulation resistance thereafter due to a good self-healing process.  In addition, laboratory tests and applications reports verify that KEMET metallized paper capacitors can withstand very high levels of dU/dt, unique to metallized paper capacitors.
