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: 3 pf, 60 pf, 90 pf, and 180 pf . These are the "stripline" types, and are sold by others at up to $12 each!
