UNL Series - A Green Alternative to Snapmounts

Why are type UNL capacitors a green alternative to aluminum Electrolytic Snap-Ins?
-Type UNL is made with solid-state polypropylene film dielectric
-Snap in aluminum electrolytics use electrolytes that are similar to antifreeze
-Extended life & reliability

User Few Components - Reduce component count and save board space!
-Type UNL film capacitors can handle up to 4x the ripple of snap-ins and 3x the voltage allowing you to replace multiple snap-ins with a single solid state capacitor.

Specifically Designed For DC High Ripple Current Applications
Constructed with low loss ElectroFilm construction, the UNL series offers high ripple current capabilities and high capacitance values making them ideal for aluminum electrolytic replacement or applications requiring high ripple current capacitors.

Advantages over Aluminum Electrolytic:

- Exceptionally low ESR
- Up to 10 times the ripple current
- 1.25 times rated surge voltage
- Non-polar
- Higher voltage ratings
- Dry construction - no electrolyte
- Improved reliability

Applications include:

- Power Amplifiers
- MRI gradient amplifier
- Induction Heating
- Fuel cell inverters
- Applications in Power Conversion (inverters and converters) requiring capacitors with high ripple, long life and high reliability
