A COMPANY IN TOUCH WITH THE NEEDS OF TODAY’S ENGINEERS

Illinois Capacitor is a leading manufacturer of aluminum electrolytic, aluminum polymer, metalized film and power film capacitors for electronics, along with super capacitors (EDLC or ultra capacitors) for an even wider range of applications.  Through our close involvement with customers and suppliers, IC has been able to consistently deliver the components most needed for today’s high performance end products.

Applications include virtually all types of electronic devices and systems, plus some applications traditionally thought of as being more in the electrical or lighting world.  Markets with the highest growth include wireless communications, electronic power technology, energy management, IGBT, solar and wind power.  Hottest circuit application areas include almost everything from bypass coupling to DC link and pulse circuits.  Supercapacitor (ultra capacitor) are blossoming, as engineers discover the role they can play in powering portable devices.

Dedicated to meeting the industry’s highest quality standards, IC manufactures leading-edge capacitors in a broad range of standard types and values.  

IC traces its roots over 80 years. Some of the most important patents in electrolytic capacitor technology were registered by IC.  Today, the company is pioneering power film and EDLC technologies, including:

• Extended Temperature
• Ultra-Low Impedance
• Direct Mount
• Super Capacitor / EDLC components up-to 165 Farads
• Custom supercapacitor / EDLC modules in virtually any voltage or capacitance

The latest product technology expansion from IC is in the field of rechargeable Lithium batteries.  These power sources offer extended power cycles vs. competitive alternatives, as well as being a safer option.

In February 2015, Illinois Capacitor Inc., and its affiliates were acquired by Cornell Dubilier Marketing, Inc.  This acquisition brings together two of the leading manufacturers of capacitors for the electronics marketplace.  For the foreseeable future, Illinois Capacitor will operate as a separate subsidiary of Cornell Dubilier, and will continue to be headquartered in suburban Chicago.

A CUSTOMER-FOCUSED COMPANY

IC differentiates itself with the highest possible service levels and product quality. The Applications Engineering Department advises engineers and buyers as to what capacitor technology best suits their needs, as well as what specifications are recommended for their unique operational variables.  With continuing changes in capacitor technology, there are more options available to the engineer to enhance performance or lower costs.  IC stands ready to assist in those decisions.

This website is constantly being updated and enhanced in functionality.  We offer the engineer the ability to search for product in almost any imaginable way, and to display detailed specification sheets in print friendly formats.  Our list of white papers and application notes also continues to grow, based on growing experience with our customers.

Many products are also available with optional value-added services to improve customer assembly operations, add mechanical rigidity in special applications or meet special tolerances.  Other value-added and custom design services are available to satisfy special needs.  Special life or performance testing can also be provided.  If you don’t see what you need, please contact us!

WORLDWIDE LOGISTICS RESOURCES

Illinois Capacitor is headquartered in the Chicago area, and has an Asian base in Hong Kong.  Our ISO certified factories are strategically located in Asia and Europe.  We maintain extensive inventories within the company and though an extensive distributor network.  IC routinely manages JIT deliveries and ships from plant to plant for greatest efficiencies. 

Our Asian Headquarters in Hong Kong offers full support to customers and factories all over Asia.  This operation is multilingual and fully able to resolve engineering and logistics issues.  We routinely work with customer personnel in Asia, as well as their contract manufacturers.  North American customers who manufacture in Asia benefit from enhanced communications, timely responses to requests and firm delivery scheduling.
