DIAMOND-LIKE CARBON (DLC) CAPACITORS

K Systems Corporation Revolutionary High Performance Diamond-like Carbon Film Capacitors Offer the Following Advantages Over Equal Value Capacitors Built by the Current State-of-the Art Technologies.

Characteristics of Diamond-like Carbon Capacitors
  • Compact Design Reduced in Size, Weight and Volume by 50%
  • High Voltage Breakdown Strength: > 8 x 106 V/cm
  • Extreme Low Dissipation Factor: < 0.005
  • Temperature Operation: -65oC to +300 oC
  • Constant Capacitance Values Over a Wide Range of Frequencies:10 Hertz to 106 Hertz
  • Diamond-like Carbon Dielectric Characteristics: Dielectric Constant (3.5-5.0), Resistivity (> 10 15 ohm-cm), Flexible, Pin-Hole Free, Optically Smooth, Chemically Inert, Environmental Resistance
  •  Packaged wound DLC Capacitors were manufactured successfully by rolling a pair of 0.5 µm DLC on double metallized polymer films with 100 % yield with and without silicon oil impregnation.
  • Packaged Wound DLC Capacitors with and without silicon oil impregnation passed the thermal cycling from -65 0C to +125 0C for 100 cycles at 100 Hz, 1 KHz, 10 KHz and 100 KHz (per MIL - STD -202, Method 107).  
  • Packaged Wound DLC Capacitors with and without oil impregnation passed the thermal aging test at 105 0C and 50 V for 500 hours at 100 Hz, 1 KHz, 10 KHz and 100 KHz (per MIL - STD -202, Method 108).

Characteristics of Aluminum Oxynitride Thin Film Capacitor
  • Produced by DC Pulsed Magnetron Sputtering Technique
  • Flexible, Pin-Hole Free, Optically Smooth, Good Thermal Conductivity, Chemically Inert, Environmental Resistance
  •  Dielectric Constant: 9
  • Dielectric strength: 6 x106 V/cm
  • Dissipation Factor: 0.005
  • Operation Temperatures: -200 0C to + 400 0C
  • Constant Capacitance Values Over a Wide Range of Frequencies: 10 Hertz  to 10 6 Hertz
  • Compatible with roll films and multilayer stacked capacitor design

Applications of High Energy Density Diamond-like Carbon Capacitors
  • More Electric Aircraft (MEA) for Air Force: The high temperature capability of the capacitors will enable electronic devices to be mounted close to aircraft engines. This enable more sophisticated engine actuators, sensors and controls to be implemented with a net reduction in weight achieved through the reduction or even elimination of wiring hardware which are necessary when the electronics has to be remotely located.
  • Pulse Power Applications for Air Force, Army and Navy.
  • Filter Applications for NASA.
  • Commercial utilities and appliances, oil well drilling equipment, power supplies, aircraft, communication satellites, trains, automobiles and medical instruments.
