The characterization of planar components such as inductors in an important step in better to understand components behavior as a function of frequency. To do this, it is essential to use a dedicated measuring device and an innovative and appropriate characterization method to achieve good accuracy. In this article, we present a new method and techniques for characterizing Zij impedance and Yij admittance parameters of passive components (resistors, capacitors and inductors) using a WK6500B impedancemeter. Obtained results are very encouraging, with good accuracy of less than 1%.
