History of Illinois Capacitor (Illinois Condensor)

1949 Illinois Condensor Catalog

Illinois Capacitor traces its roots to the very early years of the electronics industry when “Illinois Condenser” began supplying the rapidly growing radio manufacturing business.   As material, design and manufacturing technologies have changed, IC has responded with high-quality components designed for today’s advanced circuitry.

Today, the company continues to specialize in providing cost-effective, state-of-the-art capacitors to original equipment manufacturers and service organizations. With manufacturing and distribution worldwide, IC has been able to maintain strong partnerships with new and old customers.  Here are some highlights of IC achievements:
