ASC Capacitors

Engineering solutions for a changing world

ASC Capacitors has been designing and manufacturing high-quality film capacitors for over 60 years.

All of our products are designed, manufactured, and tested using lean manufacturing processes and state-of-the-art automated equipment. Our robust design method produces capacitors that are meant to last—typical designs have a life rating of 100,000 hours—and our use of vertical integration means we can offer a quality product at a competitive price.

We are the leading manufacturer of custom film and foil capacitors. In addition, we are fully equipped to perform testing to most Mil standards.
