Watercooled RF Power Pot Capacitors
External 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
CERAMIC DIELECTRICS
TWX and TWXF 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 ceramic capacitor element is
housed in a rugged silver-plated copper case.
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 TWX model is made with
a contoured, glazed insulation rim designed for use in
a relative clean, dry environment. The TWXF types feature
an umbrella shaped coating 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.

GUIDELINES
ELECTRICAL DATA AND GUIDELINES
• The main physical and electrical characteristics of the capacitors and ceramic materials used, are listed in the tables on the
general section and in the individual datasheets
• The continuous limit values of voltage, current, and power given in the diagrams must be observed.
• The rated voltage given in the tables is the peak value of the sinusoidal AC voltage or the sum of the DC and peak AC voltages
for which the capacitor is rated under continuous operation.
• The rated current in the tables is the effective value of the sinusoidal current for which the current paths of the capacitor are
designed.
INSTALLATION
• Watercooled pot capacitors (TWX and TWXF) are designed to be installed in a vertical, umbrella-up position. Other positions
may be allowed as shown on the individual datasheets. For large generators requiring multiple capacitors we recommended
a circular mounting pattern for optimum circuit performance.
• When capacitors are connected in parallel, care should be taken to mount the top electrodes of the capacitor away from the
RF-bus bar to minimize the effects of stray electromagnetic fields. The capacitors elements must not exceed a temperature
of more than +100 °C.
• The electrical connection to the inner electrode must be flexible in order to prevent the generation of the physical forces which
could damage the capacitor elements. Such forces are often generated by the dimensional differences resulting from the
normal physical tolerances of the capacitors. The capacitor’s inner electrode connector must not be used as a mechanical
support for other devices or components.
COOLING
• The cooling system is designed to operate at a maximum water pressure of 4 bars (58 psi).
• The water outlet of the capacitor must always be located higher than the water inlet in a vertical installation. This allows any
air to escape from the unit. Horizontal installations require that both water connections be at the top-side of the unit. To
preserve the capacitors from frost damages during the transport, we offer special models with outlet screws for emptying the
cooling water from the unit.
• The minimum water flow rates specified in the tables must be observed. When using antifreeze mixtures, the flow rate should
be increased by at least 20 %.
• The cooling system is designed to have a water temperature increase of < 10 °C (water inlet to water outlet) when the capacitor
is operated at full rated power and the minimum water flow rate. A water intake temperature of  30 °C is recommended. If
the cooling system of several capacitors is connected in series, the intake temperature of the coolant must not exceed 50 °C
for any capacitors.
• The pressure drop in a series connected cooling system is small. The table below illustrates the effects upon water flow rates
as a function of the number of series connected TWXF 135285 capacitors in the system with a constant intake water pressure
of 3 bars (43.5 psi).

• Intake water temperature fluctuations in excess of 3 °C/s must be avoided to prevent damage to the capacitor elements.
• A coolant temperature rate monitor must provide a fail-safe on / off power control for the RF equipment.
• Normal tap water or de-mineralized water may be used for cooling. The water must be reasonably free of CaCO3 and clear of
foreign particles or milkyness. The pH-value of the coolant should between 6 and 8.

QUALITY AND RELIABILITY
ELECTRICAL AND MECHANICAL SCREENING TESTS
All capacitors are subjected to the following tests prior to shipment:
• Capacitance value (1.0 MHz or 0.1 MHz, 20 VRMS, 25 °C ± 5 °C)
• Dissipation factor (1.0 MHz or 0.3 MHz, 10 VRMS, 25 °C ± 5 °C)
• Insulation resistance (100 VDC, 25 °C ± 5 °C)
• Dielectric strength (200 % rated peak voltage, 50 Hz, 5 minutes)
• RF power test (125 % to 140 % rated power for 10 minutes in a test generator circuit)
• Pressure test (standard: 6 bars [87 psi] for 1 minute, 25 °C ± 5 °C)
WARRANTY STIPULATION FOR WATERCOOLED CERAMIC POWER RF CAPACITORS
• Unless otherwise provided for hereinafter, warranty shall be governed by General Terms of Sale and Delivery.
• Warranty is assumed for capacitors which fail to operate owing to faults in material or production, and within the warranty
period for capacitors
• Excluded from warranty are capacitors prematurely rendered unserviceable owing to improper treatment, overloading, circuit
errors, as well as capacitors operated without observing the data given in our catalogue. Warranty is also excluded in cases
where faults can no longer be recognized on the capacitor owing to third party interferences. Warranty is only effectively
assumed when meeting the requirements referred to hereinafter.
• For claiming warranty, the defective capacitor should be returned to us, if possible in its original packing, within 14 days
following the data of failure, being accompanied by the completely filled-in and signed Original Guarantee Certificate. The
risks of transportation, as well as any shipping costs and other charges shall in any case be borne by the sender.
• Warranty can only become effective if the defective capacitor is received by us in the same condition as it was when it
happened to fail.
• We have the right to inspect any records proving the use of the capacitor.
• The decision as to whether we are obliged to assume warranty for the capacitor shall exclusively rest with us.
• When acknowledging the warranty claim, any non-repairable capacitor shall remain our property. When refusing a warranty
claim the defective capacitor will be returned at the customer’s expense only if demanded so explicitly when asserting the
warranty claim. In case examination required disassembly of the capacitor no claims for damage can be derived therefrom.
• The customer gives us the right to have the system checked in which the capacitor was operated.
• When acknowledging a warranty claim, restitution is made by supplying either a repaired and newly tested capacitor or by
supplying a new one.
• Warranty shall only extend to the capacitor itself. Any further claims for damages are excluded.
CONDITIONS OF GUARANTEE
Pursuant to the foregoing stipulations we assume warranty for these watercooled pot capacitors up to a period of 5000 hours
of operating service. Any claims for warranty, however will extinguish 24 months following the date of delivery.
