The {{Title|General Radio 505 Capacitor}} was introduced in {{Bulletin 936}} and remained available through {{Catalog S}}. | |||
The Type 505 is a secondrary standard capacitor using a silvered-mica dielectric. The capacitor is installed in a low-loss phenolic case along with Silica gel desiccant then sealed with wax. The Type 505 has almost as equally high stability as the [[1409]] Standard Capacitor at one quarter the cost. The Type 505 is found in many General Radio instruments as a capacitance standard. It is supplied in two case sizes, the small and large. | |||
