About Us
Arizona Capacitors, LLC, a manufacturer of mylar capacitors, was acquired by Electro Technik Industries, Inc. (ETI) of Clearwater, Florida in 2010 and now operates as Arizona Capacitors, Inc. ETI is a holding company which operates various subsidiaries in the passive electronic components industry including: custom magnetics, microwave components, resistors, and now mylar capacitors.
Arizona Capacitors is located on one acre and occupies over 20,000 square feet of manufacturing and office space. The company offers very competitive labor rates and a well-trained, quality conscious work force. Some of their wound film capacitor and electronic filter drawings for military and private industry components date back as far as the 1950’s, but while they are proud of their past they are constantly working on developing new products for the future.
About Mylar Capacitors
The Mylar capacitor is actually a high temperature polyester film capacitor. The Mylar film material was developed in the 1950’s by DuPont. Its technical name is BoPET or biaxially-oriented polyethylene terephthalate.
Mylar is the actual material used to make the dielectric and is used to produce both high temperature capacitors as well as high voltage capacitors. This is due to the Mylar’s excellent strength, heat resistance, and insulating properties. Mylar is the second most commonly used dielectric material next to polypropylene. It also has one of the highest dielectric constants, giving it more capacitance per volume.
Mylar capacitors have a distinct advantage. They are both smaller and stronger than their paper counterparts and can operate at a wider temperature range. The Mylar capacitor is also considered to be superior to that of the electrolytic capacitor. One drawback, however, is that it is not suitable for AC applications, due to inherent losses. So, the Mylar capacitor is mostly used in DC applications.
Mylar capacitors are used in many different products. They are used extensively in instruments, communications equipment, lasers, or wherever a more stable capacitor is needed.
