3 8 JENNINGS TECHNOLOGY Vacuum capacitors overview Jennings vacuum capacitors Features High voltage rating The dielectric strength of the vacuum permits optimized voltage rating for a given size and capacity, in addition to freedom from contamination, humidity and oxidation. High current rating Low losses and rugged copper construction permit the handling of high RF currents with convection cooling only. Some of our designs offer water and air cooling for extraordinary load conditions. Wide tuning ranges High ratio of maximum to minimum capacity makes Jennings vacuum capacitors desirable for wide tuning ranges. Low losses Losses in a vacuum capacitor are so small that for most applications they can be considered as negligible. Construction materials and the vacuum dielectric permit the handling of large RF currents at high RF frequencies that would destroy capacitors with other dielectrics. Self-healing Jennings vacuum capacitors can withstand momentary overloads that would permanently damage other dielectric materials. High altitude operation Vacuum sealing permits the operation of Jennings vacuum capacitors at high altitudes without the degradation that occurs with other types. Description and general specification Figure 1 illustrates the construction of a typical Jennings variable vacuum capacitor. Two sets of concentric cylinder plates, one adjustable and the other fixed, are enclosed in an evacuated ceramic envelope with OFHC copper seals at both ends. A flexible metal bellows, attached to a sleeve-type bearing, maintains vacuum while allowing capacitance to vary. The linear sliding motion required to vary capacitance is converted to rotary tuning via an adjustment screw; in many capacitors, direct pull tuning is an alternative. Internal breakdown voltage is primarily determined by the spacing of the opposing plates and a high vacuum level. The following are general specifications pertaining to Jennings vacuum capacitors. Current ratings are for normal convection cooling in ambient temperature of C unless otherwise specified. Maximum allowable operating temperature 1 C (7 F) for ceramic capacitor Cooling natural convection unless otherwise specified Mounting position any Rotation to increase capacity counterclockwise Variable end Heavy copper mounting surface Long life bellows allows plate movement in vacuum Patented concentric cylinder re-entrant flange construction Fixed end Capacitance adjustment screw Turning head Sleeve-type bearing Shaft provides plate movement Ceramic envelope Heavy copper plates High strength vacuum dielectric If none of our standard catalog models meet your needs, our engineers will work with you to design a custom solution to meet your specific needs. Current/voltage Maximum operating current for vacuum capacitors is limited by temperature rise and working voltage. At lower frequencies, a capacitor is a current-limiting device as a result of its capacitive reactance. At some frequencies, the internal generation of heat exceeds the device s heat-sinking capabilities, and its currentcarrying capacity is limited by thermal considerations. A current vs. frequency chart is provided for each capacitor listed. Peak voltage is limited by mechanical design of the capacitor. It does not vary with frequency. Figure 1 typical Jennings variable vacuum capacitor Two voltage ratings are provided in our product specifications: AC test voltage and working voltage.

4 VACUUM CAPACITORS, RELAYS, INTERRUPTERS, CONTACTORS AND DC CONTACTORS 9 Vacuum capacitors overview Jennings vacuum capacitors Temperature Jennings Technology vacuum capacitors are rated for a maximum operating temperature of 1 C (7 F) with normal convection cooling at an ambient temperature of C (7 F). Capacitance Fixed capacitors with a nominal capacitance above pf shall be within ±%. Capacitors with a nominal capacitance of pf or less shall be within ±%, or 0.pF, whichever is greater. For variable capacitors, the low end will be equal to or less than minimum rating. The capacitance change is substantially uniform with rotation, and there are no capacitance reversals. Capacitance is within ±% of the nominal value of the curves shown (capacity vs. turns), in the linear portion of this curve. /direct pull In variable capacitors, the linear sliding motion of the moving electrode assembly is converted to rotary tuning via a threaded shaft. The torque values given in the tables are the maximum torque needed to reach minimum capacitance when rotated with a standard lead screw; the torque required to tune away from minimum may be less than half this value. For most variable capacitors, direct pull tuning is an available option to rotary tuning. Maximum required direct pull force values are also given in the tables. Capacitance range end-stops are built into every variable capacitor. It is recommended that the user install their own external stops to prevent damage from gear-reduction drives. Mechanical life The mechanical life of variable capacitors is related to length of stroke, speed of operation, bellows material and total number of cycles. Extensive mechanical life tests have been run, operating units for complete cycles from maximum to minimum and back to maximum capacity covering 9% of the full stroke of the movable plates. Capacitors with a large bellows and a short stroke will have the greatest life expectancy under cycling operation. Our most recent variable capacitor models are rated for > million cycles, ideal for the semiconductor processing industry. Testing standards Factory All capacitors are tested for dielectric strength on a 0% basis prior to shipment. Upon customer request, certified test reports will be made available. Dielectric strength is tested using a low current, high potential source at Hz voltage. Capacitors for applications involving applied DC voltage should be tested on a DC dielectric strength meter for voltage and emission current. Jennings will test capacitors to this measure if specified by the customer. User Most users will find the Hz dielectric strength test adequate and relatively inexpensive. Jennings does not recommend DC testing being performed by the user because of safety considerations. If DC testing is performed, care should be taken not to exceed % of the peak test voltage rating of the capacitor.
