Mica capacitors

Country of Origin: Germany
Reference Number: TODE20170208001
Publication Date: 8 March 2019

Summary

A German SME offers tailor made developed mica capacitors used in professional applications where precision and high reliability are important. The products are used for research and development purposes by universities as well in industrial applications like automotive, space or electro mobility. The company is looking for partners for technical cooperation agreements.

Description

The SME is active in the production of mica capacitors. Mica as a dielectric has special properties: low dissipation factor, high dielectric strength and high temperature stability. Therefore MICA capacitors are suitable at extremely temperature conditions. 

The company offers to their customers special services: measurements, tests, burn-in and screening of single pieces or complete batches. 

They are looking for partners like universities or companies which need tailor made capacitors. Targeted type of cooperation are technical cooperation agreements.

Advantages and Innovations

The Mica material used in the capacitors is a potassium-aluminium-silicate of especially constant crystalline structure named "Muscovite, quality ruby clear". Before processing all mica foils are controlled up to the maximum theoretical limit of dielectric strength in order to guarantee constant product quality. 



An excellent stability is reached without significient gaps between dielectric and electrode as the result of applying and burning in of exactly defined silver electrodes on both sides of using of naturally aged thin mica plates. Therefore there is a high stability of capacitance and temperature coefficient. Stack technique for single mica foils and the frontal contacting ensure a special low-induction. In order to use the optimal charcateristics of mica as dielectric a special vacuum impregnation and the cleading with approved synthetic resins  is necessary. This provides besides high insulation also mechanical and climatical strength. 



The various designs of the capacitors are qualified according the most German and international standards.
