Toko Succeeds In Developing Next-Generation Coiled Power Inductor

October 14, 2009 by Jeff Shepard

Toko, Inc. has announced that it has succeeded in developing a next-generation coiled power inductor (2.5 x 2.0 x 1.2mm). Mass-production is slated to begin in April of 2010. The coiled power inductor developed is approximately 80% smaller in element volume size than our older model (4mm square). It was developed using proprietary materials, structures and methods (for which patents have been filed).

Toko states that it has also succeeded in improving the current values by a factor of two or more, with a wide inductance corresponding to 10µH. In addition, by combining the coil and the core into a single unit, the company states that its design was able to drastically reduce the audible noise normally associated with coils.

Principal applications for the inductors include cell phones, smart phones, digital still cameras, etc.
