Illinois Capacitor (IC) is a leading manufacturer of high performance capacitors including; aluminum electrolytic, metalized film, power film and supercapacitors. All IC products meet the industry’s highest quality standards. As capacitor technology changes, Illinois Capacitor remains dedicated to providing leading-edge capacitors in a broad range of values and offering engineers more options to enhance performance and lower costs.

Today, Illinois Capacitor is pioneering EDLC technology. Known as “supercapacitors,” Electric Double-Layer Capacitors (EDLC) provides the highest available capacitance values per unit volume and the greatest energy density of all capacitors. For example, Illinois Capacitor’s DCN series of supercapacitors offers capacitance values up to 3,500 Farads in a very small size. Other advantages of supercapacitors include; long life, low ESR, low heating levels during charge and discharge, high output power and improved safety.

Thanks in part to EDLC technology; utilization of Illinois Capacitor products continues to grow across several markets including; the wireless communications, electronic power technology, energy management, solar and wind power markets.
