Arizona Capacitors, Inc. is the first name in quality wound film capacitors for both commercial and military applications. These wound film capacitors include: audio capacitors, pulsed power capacitors, decoupling capacitors, motor start capacitors, snubber capacitors, sensing capacitors, and tuned circuit capacitors. These can take the form of mylar capacitors, polyester capacitors, polypropylene capacitors, and many more.

Wound film capacitors, however, are not the only thing we manufacture. We also design and manufacture custom filters including: low pass filters, feed-through capacitor filters, power line filters, and audio frequency filters.

Arizona Capacitors has dozens of manufacturer representatives located throughout the United States to accurately represent your company and provide you with timely and professional services. Our trained representatives are standing by to assist you with all of your questions and product ordering needs.

Wound Film Capacitor: Design
At Arizona Capacitors, our engineering staff has many years of wound film capacitor design and engineering expertise. Explain your application and we can design and manufacture a wound film capacitor to meet your specific needs.
We have made available here a white paper we wrote on Types of Wound Film Capacitors

Wound Film Capacitor: Dielectrics
Our standard film capacitors are wound dielectrics in paper, foil, plastic, metalized film, polyester, polycarbonate, Teflon, polypropylene, polystyrene, Kraft paper, and can feature many other combinations.

Wound Film Capacitor: Configurations
Arizona Capacitors' wide variety of wound film capacitor configurations include wrap and fill, epoxy dipped, preformed case, molded, ceramic tubular, phenolic, bathtub, tubular hermetic, rectangular hermetic, welded case, pvc tubular, and glass tubular.

Wound Film Capacitor: Typical Applications
Wound film capacitors are used in a wide variety of applications. We have designed and manufactured capacitors for by-pass, R-C networks, matched sets, pulse discharge, impulse generators, ferro resonant, laser, HID lighting, DC filtering, voltage multiplier, audio, and power supplies, to name a few.

Wound Film Capacitor: Capacitance and Voltage Ranges
The capacitance on our film capacitors range from 50 pf to 5000 uf. Our standard tolerance is + 10%, while tolerances up to + 25% are available.  We cover voltage ranges from 30 to 250 KVDC and 50 KV to 100 KHZ.

Arizona Capacitors, Inc. has manufactured a wide range of wound film capacitors for both commercial and military use.  We serve a variety of industries and applications including: aerospace, automotive, railroad, marine, audio, motor start, motor run, motor control, pump start & run, lighting, strobe lights, x-ray, medical, power utilities, instrumentation, switching, pulse, telecommunications, and test equipment. 

We maintain a filing system of over 500,000 legend film capacitor drawings that encompasses over 50 years of experience with military and commercial customers. We also house over 50 competitor catalogs, which gives us the ability to cross reference and build thousands of competitive wound film capacitors. We can also duplicate most film capacitors by reverse engineering. When you provide a sample, we can engineer an exact duplicate of any film capacitor.


History of our Company
Arizona Capacitors, LLC, a manufacturer of wound film capacitors, was formerly known as West Cap of Arizona, a division of the San Fernando Electric Company, originally founded in 1952. In our growth, we acquired Goguen Industries of Arizona in 2002.

In 2010, Electro Technik Industries, Inc., of Clearwater, Florida, acquired Arizona Capacitors, LLC, and we now operate as Arizona Capacitors, Inc. Electro Technik is a holding company which operates various subsidiaries in the passive electronic components industry including: custom magnetics, microwave, resistors, and now, wound film capacitors.

We are located in Tucson, Arizona, less than 20 minutes from the Tucson International Airport. Our property spans one acre and our facility occupies over 20,000 square feet of manufacturing and office space. We are a competitive employer and have built a well-trained, quality-conscious work force. 

Many of our wound film capacitor and electronic filter drawings date back as far as the 1950s. We have proudly served the military and private industry with quality components for over 60 years. While we are proud of our past, we are constantly working toward developing new products for the future.

Arizona Capacitors designs and manufactures all types of custom wound film capacitors including: Mylar, Teflon, polyesterpolystyrene, and polypropylene film capacitors. We build custom film capacitors, in addition to offering a line of standard film capacitors. Arizona Capacitors also manufactures oil filled and hermetically sealed film capacitors.

When considering manufacturing pertaining to wound film capacitors, Arizona Capacitors is your destination for standard and custom components. If you do not see what you need listed on our website or in one of our catalogs, give us a call for your solution. We can design a product to meet your specific needs.
