"Doorknob" , Disc, and Other High-voltage Capacitors
These are new / unused old military stock (1996 manufacturing date codes) plastic dielectric high voltage capacitors. (They look like large oil-filled types, but they are plastic dielectric.) Rated at 1 Microfarad, and 60KVDC! Original cost in large quantity in 1996 was $1,315.88 each according to demil tags. NSN is 5910011390092
These capacitors are large: 15.5 inches wide X 6.5 inches deep X 17 inches tall not including large ceramic insulator. Large insulator adds 5.5 inches to height. Weight is an impressive 80 pounds! This item cannot ship to residential addresses because of weight, but FedEx ground shipping to commercial addresses (in USA) is not a problem. We can provide shipping quotes, if you furnish ship-to address. This would probably be a most impressive Tesla capacitor! Order as our stock # HVCAP 05 Price each: $395.00! (Order Now!) "Doorknob" Transmitting Capacitors Removed from equipment. CRL type 850, HI-Q type ACO, HEC type HT or equivalent. Measurements: Diameter approx. .75 inch, length approx. .65 inch (.85 inch includ ing mounting studs).
15 kv "Doorknob" Types Removed from equipment. CRL type 857 , HEC HT57, or equivalent. Many are NPO (temperature compensated). Measurements: Diameter approx. 1.125 to 1.250 inch, body length approx. 1.3 inch (1.775 to 1.875 inches including mounting studs).
Glass Piston Capacitors, (variable)
We have a large supply of these brand-new, mil-spec, adjustable glass piston capacitors. Samples tuned from 1.1 pf to 10.2 pf, and on our hipot testers, 100% of samples withstood 5,000 volts plus. These are an EXCELLENT high voltage trimmer capacitor. Made under military contract by JFD Electronics Co., and are referred to as part # 118145-3. Individual units are imprinted with JFD VC12432C. These were assigned a national stock number (NSN) of 5910-00-575-8838. Measurements are 7/8 inches long overall. Body diameter is ¼ inch, not including the two tinned connection solder tabs. Supplied complete with chassis mounting nut. Adjust these capacitors by means if a small, flat-blade screwdriver. Use a fully insulated adjusting tool if adjusting while subjected to voltage! Original cost in large quantity at time of original purchase (years ago) was $15.37 each. Refer to our stock # GPC-01 Price each: $5.00 10 or more quantity price: $3.75 each! (Order Now!) Vitramon capacitors
Unlike other types, once they fail hipot, they are gone for good, even with current limited very low . The good part is that it takes a great deal of voltage to fail hipot! Customers who have purchased these in the past for antenna uses and other purposes have been extremely pleased, and have consistently reordered . Ceramic body measures about 1/2 inch X 3/8 inch X 5/32 inch thick . Stripline tabs may be as long as those pictured, (most are) or may be shorter (these are removed from military equipment) but will always be long enough for easy soldering . Values usually available: 40 pf, 54 pf, 64 pf, 90 pf. Not all of these values available at all times, so please verify stock by email before ordering. These are the "stripline" types, and are sold by others at up to $12 each! Encapsulated paralleled capacitors We have these two values of encapsulated ceramic capacitors, removed from military equipment. We are not certain of type, but they seem to be very similar to Vitramon types in the way they act and in the way they were used in equipment. Each block has two capacitors paralleled to yield these values blockcap1: 700 pf, tested good to 8 kv or higher (measures 1.125 inches tall X ½ inch wide) blockcap2: 3500 pf, tested good to 5 kv or higher (measures 1.125 inch tall X 1 inch wide)
Since these blocks are made up of two paralleled capacitors, the current rating will be double that of each individual capacitor. The encapsulation is a very tough, slightly flexible material, making these units almost impervious to environmental moisture. The bottom of each block is a small metal plate with two drilled and tapped holes for easy mounting to a chassis. (Foreign customers: mating screws are available at 6 for $1.00 additional. Just request when ordering. ) The top of each block has the two axial leads paralleled, soldered to a small ribbon conductor. Order as our stock number: Blockcap1 Price: $4.00 per unit Feedthrough Capacitors
We have obtained a large supply (THOUSANDS available) of these 5000 pf silver-plated, mil-spec feedthrough capacitors. These were carefully removed from military equipment (most of the equipment was brand new / unused) and are supplied complete with chassis mounting nuts and full length terminal leads. While we do not know the manufacturer's voltage rating on these capacitors, we have hipot tested multiple samples, and they consistently hipot to higher than 1,000 volts. Length is 7/8 overall, including leads. Maximum diameter is 1/4 inch. Refer to our stock # FTC-01 Price: $0.75 each! 10 or more quantity price: $0.65 each! ( Order Now! ) 1500 pf, 1 kv mil-spec feedthrough caps, Erie CK70AW or equivalent. Hard to find. Removed from equipment. Silver plated. Refer to our stock # FTC-02 Price: $1 each, or 10 for $7.50 ( Order Now! ) Erie # 2973, 5000 pf, 5 kv, 10% tolerance These Erie feedthrough capacitors are brand new, old stock, and measure 2 inches maximum diameter, and about 1/2 inch thick, not including terminals. Most are gold plated, though a few appear to be tinned. Price: $22.50 each ( Order Now! )
