Type UNL
ElectroFilm High Current Capacitors
Metallized Polypropylene Dielectric
Constructed using a low-loss polypropylene film, the UNL series of-
fers high ripple current capabilities and high capacitance values making
them ideal for electrolytic bank replacement and high ripple current
applications
Highlights / Applications
Advantages over Electrolytics
- Exceptionally low ESR
- Up to 10 times the ripple current
- Non-polar
- Higher voltage ratings
- Dry construction - no electrolyte
- Improved reliability
Typical Applications
- High Voltage Inverters
- DC Bus Link
- DC Filtering
