How can I get the parasitic capacitance of a inductor? I have a scope, current probe, function generator.
Thank you.
Thank you.
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?

Parasitic capacitance refers to the unintentional or unwanted capacitance that exists between different components or elements in a circuit.
Measuring parasitic capacitance of inductors is important because it can significantly affect the performance and stability of a circuit. It can also cause unexpected behavior and interference in the circuit.
The most common equipment used to measure parasitic capacitance of inductors is a capacitance meter or an LCR meter. These devices can accurately measure the capacitance of the inductor and other components in a circuit.
To measure parasitic capacitance of inductors, the inductor is connected to a capacitance meter and the capacitance value is recorded. The inductor should be isolated from other components and any stray capacitance should be accounted for in the measurement.
To reduce parasitic capacitance of inductors, the distance between components should be increased and the use of low parasitic materials, such as air-core or thin film inductors, can also help. Proper grounding and shielding techniques can also minimize parasitic capacitance in a circuit.
