GenRad 1422 Low Precision Capacitors 

The GenRad 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 in AC bridge measurements, either as a built-in standard or as an external standard for substitution measurements. It is available in a variety of ranges, terminal configurations, and scale arrangements to permit selection of precisely the required characteristics.

• Stability: better than 0.02% full scale per year
• Settable to 40ppm
• Low Temperature coefficient, low losses
• Wide selection to suit needs
• Two-Terminal Models Available: 1422-D, 1422-MD, 1422-ME
• Three-Terminal Models Available: 1422-CB, 1422-CC, 1422-CL, 1422-CD, CE
