KEMET PZB300 metallized paper capacitors feature a high dielectric constant with excellent self-healing properties and transient handling capabilities. KEMET PZB300 capacitors are constructed of a multi-layer metallized paper dielectric encapsulated and impregnated in self-extinguishing material meeting the requirements of UL94V-O. 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.  Typical applications of the KEMET PZB300 capacitor are interference suppressors with X2 + 2 x Y2 capacitors in a delta configuration.

KEMET PZB300 metallized paper capacitors are classified as both X2 and Y2 capacitors. X2 capacitors are generally used in high pulse applications where a failure of the capacitor itself would not expose anybody to danger of electric shock. Y2 capacitors are general purpose capacitors used in applications where a failure of the capacitor itself could expose somebody to dangerous electric shock. KEMET PZB300 is available in both X2 and Y2 classifications.
