HIGH Q VALUE, LOW VOLUME AIR CORE INDUCTOR

摘要

PROBLEM TO BE SOLVED: To provide an inductor that combines high Q value and/or lower volume to a predetermined inductance.;SOLUTION: A spirally wound inductor (58) has a tapered conductor (60). In the inductor, the height of the conductor (60) is increased from the lower position close to a center (68) of the inductor (58) to the higher position on an external edge portion of the inductor (58). Further, a spherical inductor (88) and a method of manufacturing the spherical inductor (88) are also provided. The spherical inductor includes a series of coils (96) each of which diameter is increased facing in a direction from each edge portion to the center thereof.;COPYRIGHT: (C)2008,JPO&INPIT
