Selection and calibration of capacitors for use as Standards is a challenging task, especially since the accuracies required, depening on the application, can be very demanding for the test gear as well as for the secondary- and working-standards used.
2. Capacitance Calibration The precision measurement of capacitors for the purpose of calibration is generally based on a national primary standard of high accuracy, secondary/working Standards derived from it, and a capacitance- (or LCR-) meter used for the measurement (i.e. calibration) of the devices under test (DUT).
The recommendations for the capacitor part are given in IEC 60143-1:2004. Specific information about protective equipment can be found in Clause 3 and 10.6. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision.
Electrical behavior of ceramic chip capacitors is strongly dependent on test conditions, most notably temperature, voltage and frequency. This dependence on test parameters is more evident with Class II ferroelectric dielectrics, and negligible or more easily predictable with Class I formulations.
Welcome to the Capacitor Fundamentals Series, where we teach you about the ins and outs of chips capacitors – their properties, product classifications, test standards, and use cases – in order to help you make informed decisions about the right capacitors for your specific applications.
COG capacitors are low drift too, they do not show the known aging/drift effects of ferroelectric (class II and III) ceramic material capacitors and also no microphonic effects, and overall are a good solution for laboratory Standards. They are now available also in higher capacitances.
