Watercooled RF Power Pot Capacitors  
Internal Cooling System  
FEATURES  
• High voltage, current and power ratings  
• Compact design reduces terminal self inductance and  
permit operation up to higher frequencies  
• These pot capacitors feature increased density through  
watercooling and rugged mechanical construction for a  
maximum reliability  
APPLICATIONS  
Watercooled RF power pot capacitors are designed for use  
in the tank circuit of high power RF equipment such as  
induction heating and welding equipment, dielectric heating  
or a variety of specialized RF applications.

RATED VOLTAGE

PRODUCT DESCRIPTION  
• 20 kVp  
TWXFZ pot-styled capacitors dissipate the heat produced  
under load by means of water flow around the capacitor  
elements. In order to provide protection from influences of  
the chemical / physical characteristics of the coolant, a  
glass passivation layer is applied over the cooled noble  
metal electrode.  
The electrical terminations are made directly to the noble  
metal electrodes utilizing special soldering techniques. This  
method of attachment provides a strong, rigid connection of  
unsurpassed reliability. The TWXF pot-styled capacitors  
feature an umbrella shaped insulating rim made  
from silicone elastomer to minimize the adverse effects  
of moisture, dust and other impurities in the  
working environment and to improve the characteristics of
