Capacitor Industries is composed of three marketing divisions: Motor Capacitors, Inc., Chicago Condenser Corporation, and SEI Capacitors, Inc. The combined expertise and resources of these divisions have driven our efficiency, flexibility, and dynamic growth since our establishment in 1990. With strong leadership and extensive experience, Capacitor Industries is well-equipped to navigate the challenges and opportunities of both today and the future.
Company Profile Capacitor Industries designs, develops, and manufactures premium quality, high-performance capacitors from its headquarters in Wood Dale, Illinois. Since 1990, the company has leveraged the expertise of Motor Capacitors, Inc., Chicago Condenser Corporation, and SEI Capacitors.
Our product range includes aluminum electrolytic, motor run, and high voltage capacitors, all available from a large inventory at competitive prices.
Motor Capacitors, Inc. Motor Capacitors, Inc. focuses on the capacitor needs of the Electric Motor Industry, offering both specialty and standard products manufactured in Europe and Asia. With a large inventory of metalized film capacitors, we ensure immediate shipment for applications in health and fitness equipment, industrial blowers, refrigeration, centrifuges, water pumping systems, and power conditioning.
Our products include:
- Oil-filled motor-run capacitors
- Dry-type motor-run capacitors
- Aluminum electrolytic motor-starting capacitors
- Noise-suppression (across the line) capacitors
All products are manufactured in ISO Certified, RoHS, and REACH compliant facilities. Manufacturing lead times are typically 2-3 weeks, with shipping terms FOB: Wood Dale, Illinois, and standard payment terms of Net 30 days. We also offer custom designs, sizes, and customer-specified marking and packaging, maintaining a large inventory at our Wood Dale facility.
Chicago Condenser Corporation Founded in 1945 and acquired by Capacitor Industries in 1993, Chicago Condenser Corporation manufactures high voltage capacitors ranging from 100 volts to 100,000 volts for DC, AC, and pulse discharge applications. Applications include cardiac defibrillators, airport runway lighting, radio and TV transmitters, X-Ray equipment, and scientific apparatus.
Our products are made in the U.S.A. and include:
- High-voltage capacitors in standard and specialty designs
- Snubber (Commutation) capacitors
- Custom-designed capacitors
We use polypropylene and polyester films, Kraft paper, and capacitor-grade aluminum foil in our dielectric systems, ensuring superior performance and long life. All impregnating fluids are non-PCB and non-toxic.
SEI Capacitors, Inc. Founded in 1963 as S&EI Manufacturing and acquired by Capacitor Industries in 1995, SEI Capacitors, Inc. manufactures metalized film capacitors for critical applications. Our high-speed winding machines enable the production of capacitors with polycarbonate, polypropylene, and polyester dielectric systems, achieving tolerances as precise as +/- 0.25%.
Applications include Aerospace and Avionics, Instrumentation, Industrial and Manufacturing Equipment, and Power Conditioning Systems. We also offer a full line of Aluminum Electrolytic capacitors, including:
- Computer Grade (Screw Terminal type)
- Snap-In
- Radial-Leaded Miniature
- Photo-Flash
- Non-Polarized
Capacitor Industries provides voltage ratings up to 550 VDC and offers high-temperature and long-life versions of many standard products.
