The GenRad 1403 Standard Air Capacitors are stable, three-terminal standards in decimal values from 0.001 pF to 1000 pF. For measurement at 100 pF and below, a three terminal connection increases the accuracy by eliminating the uncertainty in the measurement introduced by the capacitances between the capacitor terminals and ground.

The type 1403 Standard Air Capacitors are stable, three-terminal standards in decimal values from 0.001 to 1000 pF.
Their terminals are arranged to plug directly into the UNKNOWN terminals of the Type 1620 Capacitance Bridge or equivalent such as AH2500A Ultra Precision Capacitance Bridge.

The capacitance change is less than 0.01% at frequencies to 2 MHz for 1 pF and 200 kHz for 1000 pF standard making the standard ideal for verifying LCR meters and bridges at frequencies other than 1 kHz.

Dielectric losses are extremely low as there is no solid dielectric in the direct-capacitance ?eld.
All have shielded terminals, both of which are connected to the case.
