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.

PRODUCT DESCRIPTION

DIELECTRIC STRENGTH TEST

TWIF 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 inner noble

metal electrode.

RF POWER TEST

140 ꢀ to 180 ꢀ of rated power, for 10 minutes in a test

generator circuit

The electrical terminations are made directly to the noble

metal electrodes either utilizing special soldering

techniques or special clamping fittings. This method of

unsurpassed reliability. The TWIF 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 the

electrical field. The capacitor body is protective lacquered.

INSULATION RESISTANCE

Min. 10 000 M (at 25 °C)

OPERATING TEMPERATURE RANGE

Details of watercooling find under “Guidelines”, next pages

MARKING

Type designator, capacitance value and tolerance, rated RF

voltage, ceramic material code, production date code,

manufacturer logo, serial number.

ACCESSORIES ADDED

All watercooled pot capacitors are supplied with

the necessary ferrules and 10 mm tube fittings for the water

supply connections.
