TDK has released the MHQ1005P series of multilayer ceramic inductors with a Q factor that, depending on the type, is as good or much better than comparable, wirewound inductors.
The new components are suitable for use in low-loss RF matching circuits in devices such as smartphones and conventional mobile phones.
The series features a Q factor that is at least about the same as the value of a comparable wirewound inductor with the same inductance and in the same footprint. For example, the MHQ1005P2N7 type with an inductance of 2.7 nH offers a Q factor of 108 at 2.4 GHz.
The high Q achieved is due to materials technology and innovations in the internal structure of the inductor. The use of new materials has produced an electrode with a smoother surface that raises the device’s Q factor and lowers the dielectric constant to deliver a better self-resonant frequency.
Enhancements to the internal structure of the inductor - including thicker inner electrodes and L-shape terminals to improve magnetic flux - also help to raise the Q factor of the multilayer ceramic inductors.
The inductors are available in 27 values from 1 to 15 nH and in three tolerance levels.
