Used in applications ranging from RF to power supply filters, inductors are magnetic elements with resistance and capacitance parasitics. Inductors rely on the magnetic field that forms around a ...

Electrical ratings are interdependent. The current through a component depends on the applied voltage (waveform and duty cycle) and the component impedance. The impedance of a component depends on the ...

Core loss in inductors can adversely affect system performance. Yet, predicting core loss is a complicated endeavor, especially in complex structures such as coupled inductors. This article examines ...
