MAX-GAIN SYSTEMS, INC. - Vacuum Variable Capacitors (501

RF and Microwave Components Online Catalog

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.

Comet CV05C-650N/5

The Comet CV05C-650N/5 ceramic vacuum capacitor is rated 8-650 pf, 5 kv peak, and 63 amps RMS maximum current. New format Comet part number is CVDU-650CC/5-DEF.

Note: We have the FM1C rear flanges with one edge professionally trimmed for close mounting (does not affect operation) for $9.00 if purchased with this capacitor! (Specify FM1C trimmed edge special when ordering.) ( Order Now! )

Jennings UCSXF-1000-15S

The Jennings UCSXF-1000-15S vacuum variable capacitor is rated at 12-1000 pf, 15 kv peak, and 70 amps maximum continuous RMS.

The shaft is 1/2 inch diameter, and requires 40 turns for full travel. Maximum diameter is 4.31 inches, and overall length is 9.937 inches.

Weight is 4 pounds. Requires FM3B front flange, and FM2B rear flange, not included, but usually available at additional cost. We frequently have these capacitors in stock, as well as several very similar types with 700 pf maximum, 1200 pf, maximum, 1500 pf maximum, or 2000 pf maximum, at peak voltage ratings of from 7.5 kv to 15 kv. Inquire as to current stock, state your preference, and we will reply with currently available options.

"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!)
