About the CKES-120-15
The CKES-120-15 is a fixed vacuum capacitor manufactured by Comet. Compact ceramic-sealed vacuum capacitor with 120 pF and 15 kV for precision RF tuning and low-noise scientific circuits.
Key ratings of the CKES-120-15 include type Fixed, capacitance 120 pF, working voltage dc 15 kV, test voltage 22.5 kV, max current 50 A RMS and minimum q 7000.
Typical applications are precision RF filter tuning, scientific spectrometer circuits, high-Q resonator networks and low-noise RF measurement. Notable features: 120 pF precision value, high Q>7000 low loss, compact CKES form factor and 15 kV insulation.
Fixed vacuum capacitors use vacuum as the dielectric, which gives extremely low losses, high current capability and stable capacitance at high RF voltage. They are used in RF tank circuits, broadcast transmitters, induction heating and plasma equipment alongside power grid tubes.
