UNL7W50K-F

**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 

## **Specifications** 

- Improved reliability
