What is a fixed vacuum capacitor and how does it differ from classical capacitors?

A fixed vacuum capacitor uses high vacuum (below 10⁻⁴ Pa) as dielectric. Vs classical capacitors: 10× higher dielectric strength, zero ionization, high Q (>5000), -55..+85°C stability, 30+ year life. The only practical solution for high voltage/current RF applications.

How to choose among 71 models in CKT Series?

4 parameters: capacitance (pF), peak test (system × 1.5), RF working (~60% of peak), current. Example: 13.56 MHz / 5 kV / 50 A needing 100 pF → CKT100/15/50.

Where are the 42 kV CKT500/42/170 models used?

CKT500/42/170 / CKT500/30/170: 500 pF, 42 kV peak, 30 kV RF, 170 A, 155×160 mm. High-power broadcast (50-500 kW), mega plasma generators, large induction heating (>500 kW), tokamak. Special order.

How long does a vacuum capacitor last?

Design life 30+ years. Fixed capacitors have no mechanical cycles, unlimited electrical cycles. Typical 20-30 years. Replace signs: capacitance ±5% drift, Q drop, corona glow, arc noise.

GLVAC Fixed Vacuum Capacitor

25-4000 pF fixed capacitance, 3-42 kV peak voltage — CKT series for RF power, induction heating and broadcasting

GLVAC CKT Series Fixed Vacuum Capacitors are vacuum-insulation capacitors with fixed capacitance values, specially designed for high voltage/current RF applications. The vacuum dielectric (below 10⁻⁴ Pa) provides 10x higher dielectric strength than air or gas, zero ionization risk, and temperature stability.

71 models cover broad capacitance range: low (25-100 pF), mid (120-360 pF), high (380-1250 pF), very high (2000-4000 pF). Voltage 3-42 kV peak. Highest (42 kV) CKT500/42/170 and CKT500/30/170 for large-power broadcast and plasma.

Typical applications: induction heating, medium-frequency heating, communication transmitters, broadcast antenna matching, medical diathermy, industrial RF drying.
