6 FAQs about [Capacitor semi-finished product testing standards]
How difficult is it to calibrate capacitors for use as standards?
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.
Are chip capacitors destined for high reliability testing?
Chip capacitors destined for high reliability testing are often designed with an added margin of safety, namely maximization of the dielectric thickness, and tested extensively for electrical properties prior to burn-in (e.g., capacitance, dissipation factor, and insulation resistance).
What is capacitor fundamentals?
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.
Are cog capacitors a good solution for Laboratory Standards?
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.
What type of connector does a capacitor standard use?
The Capacitance Standards we build, in order to achieve high accuracy, are generally of coaxial (also called 'three terminal') type. That means that each of the two terminals of our Capacitance Standards is brought out through a BNC connector, with the shield of the two connectors forming the third terminal.
What is a thin film capacitor?
A relatively new class of readily available capacitors are thin film capacitors in SMD-version, using SiO2 as dielectric material. They show low dissipation factors, relatively close tolerance also in low capacitance ranges even below 1pF and are available with the same low temperature coefficent as COG.
