Panasonic release new Film Cap series for DC-link and DC filter applications
The market requirements for high voltage capacitors in industrial applications, especially for DC-link, DC filtering and snubber capacitors are high reliability and long life in a compact case size.
With the EZPE series Panasonic developed a series that is supporting with advanced technologies these requirements. It is an ideal alternative for electrolytic capacitor as of improved energy efficiency, higher voltage and ripple current level and design flexibility.
Panasonic EZPE series is produced with metallized Polypropylene film and a patterned metallization technology (100% Panasonic black box technology). The special fuse function of the patterned metallization enables high capacitance, high withstand voltage and a built-in protection function.
Features & Benefits
Long product life & high reliability
High safety function (self-healing and built-in self-protection)
Low ESR & low loss
Low heat generation
Strong against electromagnetic interference
Flame retardant (case and sealing are UL94V-0 qualified)
Compact size
