Main Question or Discussion Point
How can I get the parasitic capacitance of a inductor? I have a scope, current probe, function generator.
The easiest way will be from its datasheet. There should be a DCR (series resistance) and parallel capacitance listed. Depending on the L and C values, you may have a hard time measuring the resonance with your signal generator. Like if the sig gen only goes to 10MHz, and your inductor is 10uH with 10pF of capacitance, your resonant freq will be around 16MHz. Also keep in mind that your oscilloscope probe has capacitance (probably in the 10pF range), so that will alter your reading and needs to be accounted for.learner1 said:How can I get the parasitic capacitance of a inductor?
