0603-Size Inductors' Very High Q Cuts High-Frequency Losses

FDK Corp. has introduced the AML0603E series of multilayer chip inductors for high-frequency circuits and modules of mobile phones that require high Q factors to minimize losses. Compared to the conventional AML0603Q series, the AML0603E reduces loss by 20% to 30% in high-frequency bands, especially over 500 MHz. The chips were developed using simulation technology with computer-aided engineering, fine ceramic material technology, and multilayer process technology. The 0603-size (0.6- by 0.3- by 0.3-mm) series consists of 20 chips covering inductance values from 2 to 12 nH, the inductance range required for high-frequency products. Samples will be available in late October, with production scheduled for the end of 2006. Prices will vary due to order configuration and shipping destination.
