Dissipation Factors of 1 pF, 10 pF, and 100 pF Fused-Silica Capacitors

摘要

We describe dissipation factor measurements of 1 pF, 10 pF, and 100 pF fused-silica capacitance standards from 50 Hz to 20 kHz, using a toroidal cross capacitor and a 10 pF nitrogen-filled capacitor as the references. We also describe an analytical model that relates the dissipation factor of a capacitor to the frequency dependence of its capacitance.
