Panasonic augments its Metallized Polypropylene Film Capacitors portfolio for industrial and infrastructure use

EZPQ and EZPE Series offer high safety and humidity resistance over extended product  life

Two recently introduced series of DC-Link capacitors from Panasonic Automotive & Industrial Systems Europe benefit from key technological advantages initially developed for the automotive segment. Mainly targeted at the power inverter and switching power supply markets, the EZPQ and EZPE Series serve as AC-Link and DC-Link capacitors respectively. Both series use Panasonic’s unique patterned metallization technology. This technology delivers long-term reliability as well as fail-safe functioning for demanding applications. The patterned metallization behaves as a fuse function, disabling a segment of the metalized sheet, in effect preventing the capacitor from failing in short mode.

In addition, the use of zinc metallic spray for electrode formation as well as aluminium metallization offers increased resistance to humidity. Forming the casing with a vacuum process utilising a Panasonic-manufactured epoxy resin, results in an even thickness with no air bubbles and eddies, further increasing humidity resistance. Both EZPQ and EZPE Series capacitors have a long product life of minimum up to 100.000 hours, a wide operating temperature range of -40°C up to +85°C, are highly reliable, flame retardant and fully RoHS compliant. The devices also benefit from low ESR values as well as low losses.

Technical details of EZPE Series products include a rated voltage of 500VDC, 800VDC, 1100VDC, or 1300VDC, a rated capacitance of 10μF up to 110μF, and a capacitance tolerance of ±10% in 2-pin and 4-pin variants. The EZPE Series is also available in a low profile series at four voltage levels between 450VDC and 630 VDC, with a capacitance range from 10uF to 66uF.

Technical details of EZPQ Series components include a rated voltage of 250VAC, a rated capacitance of 12μF to 36μF with capacitance tolerance of ±10%.
