“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!)
