Capacitors and High Voltage Components, High Voltage Components//Doorknob Capacitors
These high voltage ceramic capacitors are made from a ceramic dielectric and are then encapsulated in epoxy resin. The terminal threads on the capacitors are either M4 or M5, depending on model, with a thread depth of 4mm.

With capacitance values starting at 280pF (A picofarad ‘pF’ is one trillionth of a Farad) and then rising up to 8000pF and DC (Direct Current) voltage ratings from 10kV to 50kV depending on the model chosen.

As a high power capacitor they are designed for applications which require a low dissipation factor and a small voltage coefficient, they have excellent temperature characteristics a low partial discharge and a large capacitance.

The operating temperature range of the capacitors is between -20 to +85°C with a temperature coefficient of -4700 ±1000 ppm/°C.

The insulation resistance should be measured with DC 1000V within 60 ±5 seconds of charging.

Some common applications are:
Gas laser
DC HV power supplies
Lightning arresters
Voltage distribution systems
Electron Microscopes
Synchroscopes
Electrostatic Coating Machines
