High Voltage / High Temperature Mica Capacitors

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 Paper

At 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.

Quality Assurance

CEI maintains an AS9100 / ISO 9001 Quality System.  Our dedication to quality is a prime reason for our success in the high-voltage industry. Each step in the production process begins and ends in the quality department. From grading our mica paper to final inspection, we are dedicated to high-quality standards.  Since product quality and reliability is of the highest importance, we have ensured that our engineering and manufacturing procedures conform to the following commercial and military specifications as applicable:

  •  ANSI/NCSL Z540-1 (Formerly MIL-C-45662)
  •  J-STD-001
  •  IPC-A-610
  •  ANSI/ESD S20.20

SUPPLIER QUALITY

At CEI, we realize that the relationships forged with our suppliers are key in our ability to meet customer needs and expectations.  As such, CEI utilizes a flow-down of supplier requirements QD0004 that is applicable to every purchase order.

CONFLICT MATERIALS STATEMENT

Custom Electronics, Inc. (CEI) is working to become compliant with HR4173 (the Dodd-Frank Act), specifically with regard to section 1502 – Conflict Minerals. Conflict Minerals are defined as tantalum (Ta), tin (Sn), tungsten (W), or gold (Au), often referred to as “3TG”, originating in the Democratic Republic of the Congo (DRC) or surrounding countries. CEI’s policy is to request “Conflict Free” Mineral declarations from its suppliers (see Supplier Letter below). In the event that a mineral is not “Conflict Free”, CEI will perform a corrective action by enforcing that the mineral be obtained from a “Conflict-Free” source.
