The Accu-L Multi-Layer Inductor for High Frequency Applications
Written By: Barry N. Breen | Chaim Goldberger | Leonid Talalavsky

Abstract:
The telecommunications industry today is undergoing changes. The miniaturization of electronic circuits and the use of higher frequencies in radio communication systems such as Cellular Telephones, PCN and GPS places new demands on passive components. High frequency inductors have not kept pace with the demands. AVX has responded to these requirements by putting to market a miniature (0805) high frequency SMD inductor based on thin film technology.

This article presents the basic concepts of high frequency inductors and how such low value inductors are measured and characterized. Here, too, there is a lag between the high frequency designer’s need for ever tighter tolerance parts and the ability of off-the-shelf test equipment to provide high accuracy measurement.
