UCSL-100-20S Jennings UCSL 15–100 pF Variable Vacuum Capacitor 20 kV

The UCSL-100-20S is a variable vacuum capacitor manufactured by Jennings Technology (CPI). Higher-voltage Jennings UCSL variable vacuum capacitor with 15 to 100 pF range at 20 kV working voltage for demanding high-voltage RF tuning.

Key ratings of the UCSL-100-20S include type Variable, capacitance range 15–100 pF, working voltage dc 20 kV, test voltage 30 kV, max current 35 A RMS and manufacturer Jennings Technology.

Typical applications are high-voltage RF matching, klystron input cavities, particle accelerator RF and military radar transmitters. Notable features: 15–100 pF at 20 kV, 7:1 tuning ratio, jennings UCSL series and 35 A current.

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.
