Arco has set the industry standard for dipped silvered mica and is now the most widely used mica capacitor in the world. New levels of reliability, ruggedness, and electrical excellence have been attained in the design of the product. The distinct improvements in performance afforded by Arco capacitors have resulted in their wholesale adoption and used by the electronics industry for both military and commercial applications. All Arco dipped micas not only meet but far exceed the latest revision of MIL-C-5.

The ARCO UC Capacitor utilizes the highest quality natural mica, and has electrodes made by a printing with a proprietary silver paste. The element, therefore, becomes a structure entirely from the conventional section which uses metal foils. The finished element maintains the excellent characteristics of natural mica. This design assures constant high reliability and reproducible accuracy.

These variable compression mica trimming capacitors are produced by stacking mica dielectric capacitance units. A capacitor section consists of a thin film of mica between two spring loaded nonferrous metal conducting plates: the stacked units are mounted within a ceramic container, or on a ceramic base. By alternating metal plate, mica film, metal plate, ect., and paralleling these units, any desired capacitance within the physical limitations of the ceramic base can be achieved.

These capacitors, designed for higher frequency applications where lead inductance is critical, are available for operation at temperatures up to 400°C. Their compact design is ideally suited for PC insertion, today's state of the art technology and special mounting requirements.
