Inductors Cite 100% Or Better Q Factor Improvements

The AQ105 series high-frequency inductors, suitable for matching-circuit applications in cell phones, notebook PCs, and other wireless devices, employ a proprietary simulation technique that characterizes the devices' structural attributes to produce a typical Q value improvement of 100% or higher when compared to the company’s HK series inductors. At a measuring frequency of 0.8 GHz, for example, the AQ105-2N2 device achieves a typical Q value of 67 versus 31 for the HK1005-2N2 with similar physical and electrical characteristics. At 1.8 GHz, the same AQ series part provides a Q value of 101. All in all, typical Q values for the AQ105 series range from a minimum of 8 at 100 MHz to over 120 at 3 GHz. Sample price is $0.10 each in OEM quantities. TAIYO YUDEN INC., Schaumburg, IL. (800) 348-2496.
