KEMET RC Network PMR205, PMR209 and PMR210 metallized paper capacitors feature an integrated resistor and 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 PMR RC network capacitors are constructed of a single layer of metallized paper dielectric encapsulated and impregnated in self-extinguishing material meeting the requirements of UL94V-O.  Typical applications of the KEMET PMR RC network capacitors are interference suppressors. KEMET PMR RC network metallized paper capacitors are classified as X1 and X2 capacitors while maintaining the highest possible safety regarding active and passive flammability.

Self Healing of KEMET 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, a breakdown caused by a short transient normally results in an improvement of the insulation resistance. KEMET metallized paper capacitors are to be preferred if the capacitor is to be used where uncontrolled transient voltages can occur.

Corona Resistance of KEMET Impregnated Paper Capacitors

KEMET RC Network 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 RC Network metallized paper capacitors can withstand very high levels of dU/dt, unique to metallized paper capacitors.
