METALIZED OR FILM-FOIL CAPACITOR?- Saturday, February 28, 2015

Film Capacitors come in two standard designs, a film-foil combination where plastic or paper films are interleaved with metal foils that serve as electrodes, or as a Metalized construction where film has aluminum or zinc deposited in it to serve as the electrodes.

Metalized film capacitors show there advantages where smaller applications are needed due to their smaller size and lower weight. Metalized capacitors also have a built in “healing” property where in the case of voltage stress the film will clear itself and heal the point of damage. Due to this “healing” property most metalized film capacitors are tolerant of overvoltage.

Circuits which require high currents may need a film-foil combination capacitor. The heavy foil of this combination offers low electrical resistance and excellent thermal dissipation preventing internal hot spots and optimizing the circuit efficiency.

Impregnated capacitors are recommended for high voltage circuits where corona may be a problem. Wax is suitable for a lower temperature application. For higher temperature application oil is a suitable impregnant. These capacitors can be either metalized or film-foil combination. Also, series wound units are used to prevent corona.

ILLINOIS CAPACITOR INC. ACQUIRED BY CORNELL DUBILIER MARKETING, INC.- Tuesday, February 17, 2015

Exciting things are happening at Illinois Capacitor! 

It was announced today that Illinois Capacitor Inc., and its affiliates have been 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. Its Asian headquarters will remain in Hong Kong. 

The two companies have mostly complementary product lines, with some areas of overlap. Illinois Capacitor and its customers will benefit by an expansion of product sales and distribution resources, as well as enhanced engineering and manufacturing capabilities. Cornell Dubilier will gain product breadth with Illinois Capacitor’s extensive board-level product lines, which include aluminum electrolytic, polymer, film; and EDLC (super) capacitors and modules.

Illinois Capacitor President Basil Jacobson said, “We are thrilled to be joining the Cornell Dubilier team. Both companies will be exceptionally well positioned to expand sales through broadening product offerings and sales outlets. At this time, Cornell Dubilier has very strong product distribution in the US, with IC having extensive capabilities in Asia.” Jacobson continued, “In addition, the product line expansion will create opportunities for both brands.”

Both companies are privately held and both have grown up with the electronics industry. Illinois Capacitor traces its history back over 80 years, with Cornell Dubilier’s roots extending over 105 years! There are also many shared values among the two organizations, with very high emphasis on product quality, customer service and delivery. 

Illinois Capacitor Introduces Quick Release Motor Run Capacitor- Tuesday, February 17, 2015

MOTOR RUN CAPACITORS WITH EXCLUSIVE QUICK CONNECT WIRE INSERTION SOCKETS THAT DOUBLE AS TERMINAL BLOCKS

Illinois Capacitor QPC Motor Run Capacitors are quicker to
install and offer the durability and reliability you need.

  • Standard values from 0.4 to 10µF; 250 to 450 VAC, 50/60Hz
  • Operating temperature ranges from -25°C to +85°C
  • Exclusive locking push-wire contacts speed installation and eliminate the need to solder
  • Multiple contact option eliminates the need for terminal strips
  • Fast installation with slide-lock mounting brackets
  • Very rugged, flame-retardant (UL94V-O) case
  • UL810, IEC 566-1982, CNS4327, JIS C4908

Designed for continuous use in motor run applications and for power factor correction.

QPC Series Motor Run Capacitors can save significant installation time when compared to conventionally leaded or terminated devices.  As shown below, just press an 18-20 gauge wire into one of the sockets and it becomes locked in place.  If you need to make a change, slide the tip of a probe or a pin into the adjacent operating hole and the wire can be removed.  The metal mounting bracket also speeds assembly, as it can be mounted first.  Just slide the capacitor onto the bracket and it locks in place.
