Vacuum Variable Capacitors Max-Gain Systems, Inc. offers a wide line of vacuum capacitors, both fixed and variable, at absolute lowest prices! We have many removed from equipment, from commercial or military sources, as well as new surplus. See item descriptions. All are fully satisfaction guaranteed. On receipt, if not delighted, contact us for refund or replacement, if available. All you ever risk is shipping! Our inventory changes constantly, and many items are not shown here. If you do not see what you want, please email your requirements. Flanges are required for mounting certain types of vacuum capacitors, both variable and fixed. See item descriptions regarding required flanges, if any. We frequently have these mounting flanges available for sale, either with capacitor purchase, or separately. (Inquire for current availability and pricing) Click this link for a listing of Jennings flanges, complete with illustrations and dimensions! (We also carry many Comet flanges.) We have available large inventories of spare parts for vacuum capacitors, including pullers, shafts, bearings, flanges, etc., even for obsolete types! We offer hipot testing and diagnostic services, (to 60,000 volts) and in some select cases, we can perform repairs and restore "sick" capacitors.
If you require capacitors not in our surplus or used stock, or require factory new-in-box stock only, we are an authorized factory dealer for both Comet and Jennings Technology, and can offer all Comet and Jennings new stock at BELOW suggested list pricing! If you have surplus motor-driven vacuum capacitors or variable inductors (such as were found in military antenna couplers) and wish to slow down the drive motor for more precise tuning, CLICK HERE for a link to an instructional page.
This capacitor is the 15 kv rated version of the Jennings type CSVF-500 / UCSF 500 0107 (shown above). Rated 12-500 pf, 15 kv peak, the CSVF-500-0315 this capacitor accepts the Jennings FM-2 front flange and Jennings FM2S rear flange, available at additional cost. Maximum allowable current is 65 amps at approximately 3.5 Mhz. Diameter is 3.5 inches, and length overall is 7.88 inches. Weight is 3 pounds. Shaft diameter: 1/4 inch. Hipot tested, and fully satisfaction guaranteed. Sorry, but we are temporarily out-of-stock on this item. Price: $295 each (capacitor only). FM2 front flange or aluminum block front mount, and FM2S rear mount are available at extra cost. ( Order Now! ) This capacitor is the Comet (precision manufactured in Switzerland) equivalent type to the Jennings type CSVF-500-0315 shown above, and has similar ratings of 12-500 pf, 15 kv peak. (For detailed ratings, see above.) Shaft is same diameter as the CSVF-500-0315, but is approximately 1/4 inch longer. This capacitor accepts the Jennings FM-2 front flange and Jennings FM2S rear flange, (or the Comet equivalent parts) available at additional cost. Hipot tested, and fully satisfaction guaranteed. Price: $295 each (capacitor only). (Order Now! ) Jennings types UCSF-500-10N and UCSF-500-15D
Some of the units pictured are shown with optional front or rear mounting flanges. The FM2 (front) and FM2S (rear) flanges are not included, but are normally stocked items, available at extra cost if desired. Price: "Out of spec" and "budget" capacitors: If you want the quality and performance of vacuum capacitors, but the budget just won't allow it, (or if you are just looking to save some money) we frequently have "out of spec" capacitors . These capacitors do not meet the specifications for the particular model . This can happen because of many reasons, but they are still perfectly usable in other capacitance ranges or maximum voltages . For instance, we might have a type that is listed at 15 kv, but tests good to 12 kv . In this case, we will not sell it to a user who needs 15 kv ratings, but if you need only 5 kv, 7 . 5 kv, or 10 kv, this capacitor would do nicely . If you want us to check our "out of spec" shelves for current stock, just tell us your capacitance range and voltage requirements (and current rating if you know it . . . or approximate power level) and we will let you know what we have available at steep discounts! "SCRATCH AND DENT" We also frequently have in stock many vacuum capacitors which have cosmetic blemishes such as dents, which would not meet our high standards for regular sale, but which still check good, both in range, and in their ability to withstand voltage . Some dents will damage or totally destroy a capacitor . Others, if they occur in just the right places, cause no harm at all . We have the knowledge and test capability to make these determinations, and if they pass our stringent testing, sell these units at discounted prices with our regular guarantee! If interested in these units, please inquire as to current availability . If you don't see what you wanted: These pages show only a fraction of the stock we have available . We have many thousands of vacuum capacitors, both fixed and variable, as well as vacuum relays . This stock changes daily . If you have requirements for items not listed in these product lines, please Email, and our knowledgeable staff will search our inventory . (Don't forget to give us your email address and contact information!)

Jennings type CSVF-500 - 0315 
Comet type CV1C-500TN/15 
These are the glass version of the newer ceramic CSVF-500, shown elsewhere on this page. Many builders like the look of the clear glass envelope, which allows a view of the interior plates. The UCSF-500-10N528 and the UCSF-500-15D912 are pictured. Electrical ratings are 12-500 pf, and 10 kv peak voltage for the "-10N" and 15 kv peak voltage for the "-15D". Maximum rated current is 55 amps RMS continuous. They are physically the same, measuring 3.6 inches maximum diameter (90.68 mm), and 7.7 inches long (195.33 mm)overall. Weight is 2 pounds, 2 ounces. Removed from equipment, thoroughly checked, and guaranteed.
