THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 Water Cooled RF Power Pot Capacitors, External Cooling System DESIGN SUPPORT TOOLS AVAILABLE

FEATURES

  • High voltage, current, and power ratings
  • Compact design reduces terminal self inductance and permits high frequency operation
  • Increased power density is achieved through water cooling. Enhanced reliability is achieved with a rugged mechanical design

APPLICATIONS

Water cooled RF power pot capacitors are designed for use in the tank circuits of high power RF equipment such as induction heating and welding equipment, dielectric heating, and a variety of specialized RF applications. PRODUCT DESCRIPTION TWX and TWXF pot-styled ca pacitors dissipate the heat produced under load by means of water flow around the capacitor element. In orde r 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 copper case. The electrical terminations are directly soldered onto the noble metal electrodes, providing a strong, rigid connection of unsurpassed reliability. Th e TWX model is made with a contoured, glazed insulation rim designed for use in a clean, dry environment. The TWXF types feature an umbrella shaped coating rim ma de from silicone elastomer to minimize the adverse effects of moisture, dust, and other soiling in the working environment, and to improve the characteristics of the electrical field. MARKING Type designator, capacitance value and tolerance, rated RF voltage, ceramic material code, production date code, manufacturer logo, serial number. ACCESSORIES ADDED All water cooled pot capacitors are supplied with the necessary screws / nuts and contact plates to make the connection to the electrode terminals. Ferrules and sleeve nuts for the water supply connections are also included. CAPACITANCE RANGE 100 pF to 10 nF CAPACITANCE TOLERANCE ± 20 %; ± 10 % CERAMIC DIELECTRICS

  • The main physical and electrical characteristics of the capacito rs 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 th e sinusoidal current for which the current paths of the capacitor are designed. INSTALLATION
  • Water cooled 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 di fferences 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 in stallations 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 milkiness. The pH-value of the coolant should between 6 and 8. N u m b e r o f c o o l i n g s y s t e m s i n s e r i e s 1 2345

THE PRODUCTS DESCRIBED HEREIN AND THIS DOCUMENT ARE SUBJECT TO SPECIFIC DISCLAIMERS, SET FORTH AT www.vishay.com/doc?91000 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 V RMS, 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 WATER COOLED CERAMIC POWER RF CAPACITORS
  • Unless otherwise provided for hereinafter, warranty shall be governed by General Terms of Sale and Delivery.
  • Warranty is assumed for capacito rs which fail to operate owing to faults in ma terial 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 capaci tor should be returned to us, if possible in its original packing, within 14 days following the data of failure, being accompanied by the complete ly 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 ca pacitor 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 cl aim, restitution is made by supplying either a repaired an d 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 water cooled 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. RELATED DOCUMENTS General Information www.vishay.com/doc?22071
