FDK Corporation (Tokyo Stock Exchange 1st section: code 6955) announced the development of the AML0603E series of multilayer chip inductors for high-frequency circuits and modules of mobile phones that require high Q factors*, which achieve the best high-frequency low-loss characteristics of any multilayer chip inductor available today. Compared to the conventional AML0603Q series, the AML0603E increases Q factors while reducing high-frequency loss by 20 to 30 percent in high frequency bands, especially over 500 MHz.

Mobile phones have adopted numerous functions and downsized in the pursuit of convenience in recent years. With the accelerated trend to have digital TV tuners, GPS modules, and so on in mobile phones, further downsizing and power savings are sought to deal with multi-functionalized devices.

In response to the above demands, FDK has released 0603-size (0.6 x 0.3 x 0.3mm) chip inductors ahead of other companies. FDK introduced the AML0603E series with optimal high Q factors. These inductors are developed by using simulation technology with computer aided engineering, fine ceramic material technology, and multilayer process technology. By using the 0603E in RF circuits such as power amplifiers, power savings are achieved by making RF circuits with low-loss when compared to the use of 0603Q.

The 0603E series consists of 20 products covering inductance values from 2 to 12 nanohenries (nH). Corresponding to various needs for high frequency circuits and modules, they cover the major inductance range of high frequency products. Pricing may vary due to order configuration and shipping destination. Samples will be available in late October and volume production will begin at the end of 2006. The AML0603E series will be exhibited in CEATEC JAPAN 2006, at booth 6E104, to be held at Makuhari Messe in Chiba, Japan from Oct. 3-7, 2006 and in ELECTRONICA 2006, in Hall B5-468, to be held in Munich, Germany from Nov. 14-17, 2006.

Note: * The Q factor or quality factor is a measure of the rate at which a vibrating system dissipates its energy. A higher Q indicates a lower rate of energy dissipation.
