Apr. 19, 2016 FDK CORPORATION

Multi-layer power inductor "MIPSCZ1005 series" FDK CORPORATION (Tokyo Stock Exchange 2nd Section: Code: 6955) developed the multi-layer power inductor of MIPSCZ1005 series (1.0mm x 0.5mm x 0.75mm high max) which realize to downsizing, low loss characteristics and high DC bias characteristics. The MIPSCZ1005 is the most suitable power inductor for the power supply circuit of mobile devices such as mobile phones, power supply module and wearable devices which are attractive in recent years. Mobile devices need the higher electric consumption for the corresponding to the high-performance and the high-speed tele-communication. In addition, the number of power inductor used in power supply circuit for mobile devices continued to increase with the high and multiple functionality. Therefore, power inductors are required to be high electric performance (low loss characteristics, high DC bias characteristics, etc.) and downsizing. To meet these requirements, FDK has successfully developed the multi-layer power inductor of MIPSCZ1005 series, which are 40% smaller than conventional model of MIPSZ1608D series keeping the equal level for low loss characteristics and DC bias characteristics by adopting our original “ferrite material technology”, “magnetic circuit design technology” and “high precision printing and lamination technology” cultivated by multi-layer inductors for high frequency devices. By this new series, we will contribute to reducing the electric consumption by high efficiency in the power supply circuit of high-frequency drive, and contribute to use of high-density mounting and the thinning of modules more than conventional products in the mobile devices and small power supply module such a limited mounting footprint. FDK will continuously expand the variation of line-up of “MIPSCZ1005 series” to respond to customer needs by seeking the possibility of ferrite material. Sample of the product will be available from May, 2016. It would be exhibited in the FDK booth of TECHNO-FRONTIER 2016 to be held at Makuhari Messe from April 20 to 22.
