Abstract

This paper investigates the frequency response of a thin toroidal inductor (200 um) made of 4C65 ferrite and wound with 18 turns. A hybrid methodology combining analytical modeling, numerical simulation using HFSS, and experimental characterization with a 6500B impedance analyzer. The analysis focuses on two key parameters: the self-inductance (L) and the series resistance (R) as functions of frequency. The comparative study between theoretical, simulated, and measured results demonstrates that the inductance remains close to 1 uH over the 1 MHz10 MHz range. The DC resistance (RDC) is approximately 12 m while the simulated and measured AC resistances (RAC) exhibit good agreement. However, analytical models show noticeable deviations beyond approximately 1 MHz, revealing their limitations in predicting high-frequency behavior.
