The typical Q factor of the 3.9 nH type is 35 at 1 GHz. This value is as good as a comparable, but more expensive, wirewound inductor and 25 percent higher than TDK’s existing MLG0603W inductor. The high Q factor and small dimensions achieved by the MHQ0603P multilayer inductor are a result of TDK’s advanced materials technology and innovations in the internal structure of the inductor. This enables the electrodes to be produced with a smoother surface, which raises the component’s Q factor and lowers the dielectric constant, thus delivering a higher self-resonant frequency.
Thanks to its miniature size and high Q, the new MHQ0603P is designed to make RF circuits in multifunctional devices such as smartphones and tablet PCs more efficient. The new MHQ0603P inductors join the existing components in case size 1005 to form an even more versatile lineup of high Q multilayer inductors.
