Custom Electronics specializes in providing mica capacitors and subcomponents designed for high voltage and high temperature applications in the aerospace industry, particularly for space and satellite applications.
Since its establishment in 1964, CEI has been at the forefront of designing and manufacturing top quality custom reconstituted mica paper capacitor. With a portfolio boasting over 15,000 unique designs, CEI's capacitors find applications in a multitude of demanding scenarios. Throughout its history, each high voltage mica capacitor has been meticulously tailored to meet the specific needs of individual customers.
These capacitors serve various critical applications, including power supplies for communication and weather satellites, pulsed power systems, radar transmitters, guidance and surface radar systems, high voltage transmitters, High Voltage Traveling Wave Tube (TWT) power supplies, ignition systems, laser devices, and transmitter power supplies for electronic countermeasures (ECM).
CEI utilizes "Grade A" mica paper in its capacitors due to its exceptional dielectric properties. Mica paper, composed of flexible, continuous, and uniform layers of reconstituted mica, serves as excellent electrical insulating material with a paper like structure, formed by small, thin overlapping platelets.
The mica paper employed by CEI undergoes rigorous quality checks, ensuring the production of high voltage reconstituted mica paper capacitors. These capacitors are trusted by leading high tech companies for applications in space age radar, missiles, satellites, ignition systems, detonation systems, cryogenic systems, transmissions, lasers, medical equipment, and oil and gas exploration.
Beyond mica capacitors, CEI extends its offerings to a range of electronic assemblies and modules. These modules typically include capacitors, resistors, diodes, coils, spark gaps, and voltage dividers, encapsulated with CEI's unique epoxies in molds or housings.
Designed for high altitude applications and diverse environments, modules feature terminations like wire leads, threaded studs, turret terminals, high voltage connectors, and cable assemblies. The operational temperature of modules varies based on internal components, epoxy selection, and the intended use.
CEI's products bring numerous advantages to the space and satellite industry, including radiation resistance, high temperature operation, corona resistance, capacitance stability concerning temperature, voltage, frequency, and mechanical stresses, shock and vibrational resistance, as well as fractional voltage or charge loss.
The company's engineering team stays abreast of the latest technological developments in materials, processes, and packaging, ensuring optimal designs. Collaborating closely with customers' mechanical and electrical design teams, CEI delivers customized capacitor designs with minimal response time.
