Evaluation of Three-Terminal and Four-Terminal Pair Capacitors at High Frequencies

摘要

The low frequency (1 kHz) capacitance values of three-terminal and four-terminal pair air dielectric capacitors can be extrapolated to higher frequencies if the residual series inductance is known. A resonance method for evaluating the residual series inductance of these capacitor types, together with the extrapolation procedure, is described. For the region where the product of capacitance in farads and frequency in hertz is 0.01 or less, uncertainties of one percent or less may be obtained.
