TOSW 118115 www.vishay.com Vishay Draloric Watercooled RF Power Barrel Capacitors for Dielectric Heating Equipment FEATURES These capacitors feature a high Q-factor of greater than 10 000 which makes them ideal in operating frequency range from 0.1 MHz up to 30 MHz where high voltages and currents are present. This capacitor type can be used as replacement for fixed vacuum capacitors. The construction provides the advantage of a long lifetime without vacuum deterioration. The TOSW 118115 has additionally watercooling systems on both electrodes. That provides very high power ratings up to 1940 kvar.

The fittings must not be used as a mechanical support for other devices or components. Each cooling system is designed to operate at a maximum water pressure of 15 bars (218 psi). 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 be between 6 and 8. INSTALLATION The electrical connection to one electrode must be flexible in order to prevent the generation of 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.
