Since 1964 Custom Electronics has successfully designed and manufactured the highest quality custom reconstituted mica paper capacitors available. Our capacitors (>15,000 designs) are used in many of the most demanding applications imaginable. Historically, every one of our capacitor designs was tailor-made to meet a specific customer’s needs. |
Custom designs are available as well. Click here to learn more. |
Our Mica PaperAt Custom, we use “Grade A” mica paper in our capacitors because it is an excellent dielectric. A dielectric is a material that does not conduct electricity, but one that can sustain an electric field in high-voltage capacitors. Mica paper consists of flexible, continuous and uniform layers of mica that are reconstituted or reformed into paper-like electrical insulating material composed of small, thin overlapping platelets. Custom’s mica paper passes the most intensive series of quality checks in the industry. The result is high-voltage reconstituted mica paper capacitors that are used by leading high-tech companies for their space-age radar, missile, satellite, ignition, detonation, cryogenic, transmission, laser, medical and oil-and-gas exploration systems. |
