Glossary of High Voltage Capacitor Terms:

MICA: Mineral silicates H2KA13(Si04 )3 naturally occurring. An excellent
insulator resistant to temperatures. Used as a dielectric in capacitors
and as insulation in high voltage, high temperature environments.

Reynolds High Voltage Capacitors with mica paper are manufactured with reliability as the prime
consideration. Reynolds engineers have developed and implemented an extensive reliability proofing program consisting of thermoset epoxy impregnated MICA dielectric systems over a period of 540,000 unit hours of operation. (consult the factory for reliability data)

Reynolds High Voltage Capacitors are available in a variety of configurations:

  • Raw Sections: For use in potted/embedded next higher assemblies.
  • Wrapped and End capped: For stand alone applications requiring no subsequent potting or embedment processes. Wrap material is Mylar® or woven glass.
  • Fiberglass Encased Epoxy-filled Construction: Provides the attributes
    of the epoxy molded configuration with no hard tooling required.
  • Low Inductance/High Current: Ideal for Exploding Foil Initiators (EFI).
    Micapacitors designed for very low inductance (6nH) and high currents (3 to 10 kA) are available in any of the above configurations. Similar low inductance, high current designs are available for Exploding BridgeWire initiators (EBW).

High Voltage capacitors with mica paper

Applications
Epoxy Molded Capacitors
Epoxy molded assemblies can be configured in solid complex shapes and mounting arrangements. Units can contain several voltage and capacity values and a variety of terminations.
These configurations offer stand-alone shock, vibration and environmental security with Mica reliability.
Epoxy molded capacitors are currently qualified for use on major military and commercial programs.

Mica Capacitors in Voltage MultipliersMica Paper capacitors in Voltage Multipliers
Raw high voltage capacitors are used in Reynolds Mica plier voltage multipliers. These units have output voltages ranging to 160 kVDC.
Mica pliers are used in a wide range of military and commercial applications.
Typical applications are: CRT anode and focus supplies for airborne EFIS (Electronic Flight Instrumentation Systems), X-Ray equipment and low power (mini) TWT's.
Mica Paper capacitor Variety
Shown arevarious configurations: Epoxy molded, fiberglass encased with epoxy filling, wrapped and end capped. Also shown are capacitors attached to low inductance strip lines for use on EFI and EBW initiators and ESA&F systems.

Mica Paper
Only the finest Mica paper is used in the manufacture of Reynolds Mica paper capacitors. The material comes in a roll of a specified width and thickness and undergoes a thorough incoming inspection before use. Precision winding machines are used to wind the Mica material into a custom, computer generated configuration.
Mica Paper used in Mica Capacitors, High Voltage Capacitors
Raw Mica CapacitorsRaw mica paper capacitors
During the winding process, tabs are inserted to serve as termination points. The wound sections are then impregnated in a special epoxy and pressed to a specific density. The sections are then cured under pressure and post cured in an oven.
After extensive testing, the units are ready to be assembled into a next higher assembly by the customer or at Reynolds Santa Maria facility.
Wrapped & End Capped  capacitors
The raw capacitors are wrapped in
Mylar® or woven glass, have lead wires
attached and are end filled with epoxy. These units are a stand-alone configuration which require no subsequent potting or embedment processes.
