UCSL-200-25S Jennings UCSL 25–200 pF Variable Vacuum Capacitor 25 kV

The UCSL-200-25S is a variable vacuum capacitor manufactured by Jennings Technology (CPI). Largest standard Jennings UCSL variable vacuum capacitor with 25 to 200 pF at 25 kV for very high-voltage, high-power RF applications.

Key ratings of the UCSL-200-25S include type Variable, capacitance range 25–200 pF, working voltage dc 25 kV, test voltage 37.5 kV, max current 55 A RMS and manufacturer Jennings Technology.

Typical applications are very high-voltage RF matching, high-power radar transmitters, accelerator RF cavities and high-power broadcast tuning. Notable features: 25–200 pF at 25 kV, 8:1 tuning ratio, highest-voltage UCSL standard and 55 A current capability.

Variable vacuum capacitors allow the capacitance to be tuned under high RF voltage and are the key element of RF matching networks for semiconductor plasma processing, broadcast antenna tuning and industrial RF generators. Selection is based on capacitance range, test voltage, RF current and drive type.
