PRECISE MEASUREMENT OF THE TEMPERATURE COEFFICIENT OF CAPACITANCE

Abstract

Sources of errors in the measurement of temperature coefficient of capacitance are discussed. The most important source of error is in the sample holder. The addition of a shield around the 'high' contacting spring greatly reduces errors due to the sample holder and makes it possible to measure increments of capacitance over the range of -55 C to 85 C with an accuracy of 0. 001 micromicrofarads. A technique for the automatic measurement of temperature coefficient of capacitance is also described.
