The 1407D is a used Capacitance Standard from General Radio. Engineers use direct current (DC) voltage standards to calibrate, standardize, normalize, and monitor drift, verify linearity, and establish regulation in electronic equipment. Standards are important during electronics compliance testing. Phase angle standards are ideal for calibrating many different electronics, including power analyzers, vector voltmeters, phase meters, phase sensitive instruments, and resolvers.
0.01 uF Standard Capacitor
The Genrad 1407D is a standard capacitor that consists of a silvered-mica and foil stack which is clamped under heavy spring pressure for mechanical stability. Sealing the mica capacitor in the case with a desiccant makes it possible to reduce the insulating material, other than mica, to a minimum. The only insulation except mica and dry air is a Teflon bead in the connector and a small amount of low-loss rubber in the gasket sealing the connector.
