GenRad 1403 Series High Frequency Standard Capacitor

• Available in values from 0.001 pF - 1000 pF
• Excellent Performance at high frequencies
• ISO-17025 Accredited Calibration Included with the Standard

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 GenRad 1403 High Frequency Standard Capacitors are ideal for use with the GenRad / IET 1615-A Capacitance Bridge as the terminals are arranged to plug directly into the unknown terminals of the 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 not detectable meaning that Df and tan Delta are essentially zero; there is no solid dielectric in the direct-capacitance field. All have shielded terminals, both of which are insulated from the case.
