For capacitors that are 10 μF or larger, a lower frequency of 120 Hz is used. Typically, a 1 kHz test frequency is used to measure inductors that are used audio and RF circuits. And a 120 Hz test frequency is used to measures inductors that are used for filter chokes in power supply.
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).
There are several ways to test a capacitor to see if it still functions as it should. Disconnect the capacitor from the circuit it is part of. Read the capacitance value on the outside of the capacitor. The unit for capacitance is the farad, which is abbreviated with a capital “F.”
Disconnect the capacitor from its circuit. Set your multimeter to its resistance setting. This setting may be marked with the word “OHM” (the unit for resistance) or the Greek letter omega (Ω), the abbreviation for ohm. If your unit has an adjustable resistance range, set the range to 1000 ohm = 1K or higher.
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.
The Q-factor or the quality factor of a capacitor at the operating frequency ω is defined as the ratio of the reactance of the capacitor to its series resistance. Q = (X C / R). It is a dimensionless quantity. D-Factor – The dissipation factor of a capacitor is the power loss when AC is applied through the capacitor.
