Type UNL, DC Link and Filter Capacitors
High Capacitance, High Current, Board Mount
Constructed using a low-loss polypropylene film, the UNL series
offers high ripple current capabilities and high capacitance values
making them ideal for electrolytic bank replacement and high
ripple current applications.
Highlights
Advantages over Electrolytics
- Exceptionally low ESR
- Up to 10 times the ripple current
- Non-polar
- Higher voltage ratings
- Dry construction - no electrolyte
- Improved reliability
