VARIABLE INDUCTANCE ELEMENT

摘要

PURPOSE: To provide a variable inductance element having a high Q factor and capable of finely adjusting the inductance value efficiently and reliably. CONSTITUTION: An inductor pattern 4 is formed on the upper surface of an insulating board 1. The pattern 4 is a laddershaped electrode comprising a V-shaped frame 4a and a plurality of horizontal bars 4b spanning two arms 41 and 42 of the frame 4a. The bars 4b are to be trimmed to adjust the inductance value. The bars 4b are arranged at substantially equal intervals. The arms 41 and 42 are arranged at substantially 45°with respect to the bars 4b.
