Vitramon capacitors

We have a good selection of values of these ceramic Vitramon capacitors for sale . While we cannot find much data on these caps, they seem to be rated by the manufacturer at about 2 kv .  We have tested quite a few, and they hipot MUCH higher . . . some as high as 20 kv (!), then they flash internally, and they are dead .

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:  3 pf, 60 pf,  90 pf, and 180 pf .

These are the "stripline" types, and are sold by others at up to $12 each!
