    In-depth On Inductors with KEMET Part 2

    The Learning Circuit | element14 presents |  Project Videos



    Karen welcomes back William from KEMET to talk more about inductors. Together they conduct experiments to show off some characteristics of various types of inductors. In the first experiment, William uses his store-bought H-field probe, while Karen uses her home-made probe to show the effects of crosstalk.  After connecting each inductor to a function generator exporting a square wave, they use the H-field probe to see the EMI of various inductors on an oscilloscope, demonstrating why shielding in inductors is important. In the second experiment, William and Karen use heat sensing cameras to show the temperature changes when the rated current of an inductor is exceeded. In the third and last experiment, William uses a circuit he created to show saturation current in ferrite core inductors.
