A Characterization of Ceramic SMD Inductors for PCB Applications

Abstract

In this paper, a measurement technique, characterization and parameters extraction of SMD inductors for PCB applications are presented. These components, manufactured by Fair-Rite, are measured and characterized using a vector network analyzer E5071B and adaptation test fixture on PCB board. Since the behavior of the component depends on the environment where the component is placed, measurement results strongly depend on the choice of the PCB. Two new adaptation test fixtures in PCB technology on different board type are presented. The equivalent circuit parameters are extracted in closed form, from an accurate measurement of the board-mounted SMD inductor S-parameters. The extraction of parameters (intrinsic and extrinsic) of SMD inductor is shown.
