Laser Discharge Capacitors Ceramic 20 - 50kV

This high voltage resin encapsulated disc capacitor range features a new strontium based, low-loss, high permittivity dielectric. It has been specifically designed to function in circuits with high peak current and high repetition rates such as those found in gas laser applications.

Features

  • Resin Encapsulation - which in conjunction with the high dielectric strength ceramic allows for high energy densities.
  • Low dielectric loss resulting in low self heating
  • Linear temperature coefficient of capacitance
  • Negligible piezoelectric/electrostrictive effect - allowing use in extremely high peak current (fast discharge) / high shot life applications
  • Low DC and AC voltage coefficients

Applications include

  • Gas Lasers
  • DC Power Supplies
  • Electrostatic Copying Machines
  • Lightning Arrestor
  • AC Voltage Distribution
  • X-Ray Power Supplies
