For many years, since July of 1952, the headquarters for Plastic Capacitors, Inc. was located on the northwest side of Chicago, but in 2014 PCI was purchased by Electro Technik Industries, Inc. and was moved to the Tucson facility along with it's sister companies, Arizona Capacitors, Inc. and Custom Suppression, Inc.
The PCI product lines were and still are today a combination of off-the-shelf and special High Voltage products. About half of sales represented are custom designed items that are not contained in this Web Site. Capacitors for 250KV RMS 60MZ powerline use or high frequency AC; power supplies for X-ray, CAT scanners, lasers and electrostatic coating; are examples of commonplace production at PCI.
