GENERAL RADIO-1422CB-VARIABLE CAPACITOR Simple Type: Capacitor
The 1422 is a stable and precise variable air capacitor intended for use as a continuously adjustable standard of capacitance. One of the most important applications is an AC bridge measurements, either as a built-in standard for substitution measurements. It is available in a variety of ranges, terminal con?gurations, and scale arrangements to permit selection of precisely the required characteristics. The 1422-CB and CL are three-terminal capacitors with shielded coaxial terminals for use in three-terminal measurements. The calibrated direct capacitance is independent of terminal capacitance to ground, and losses are very low. The 1422-CL has particularly low, constant terminal capacitance, making it suitable for measurement circuits in which high capacitance to guard cannot be tolerated.
