Over the years with the increase in multiband capability, multi-functionality and more sophisticated functions, the configuration of the RF circuits in smartphones and other compact mobile devices is becoming more complex, and the number of components being incorporated is increasing. At the same time, the volume accounted for by the batteries inside these mobile devices has become larger and larger, necessitating the RF circuits to be configured in more limited spaces. This is one reason for the rising demand for ultra-compact RF inductors with high Q characteristics capable of reducing circuit loss to the absolute minimum.
To meet these needs Murata Manufacturing has introduced a new line of film-type high-frequency chip inductors in the ultra-compact 01005 size (0.4 x 0.2 mm). The LQP02HQ series of inductors whose Q characteristics are further improved over those of the company’s LQP02TQ series. Using the company’s latest proprietary microprocessing technology, these products feature the optimum coil patterns and L-shaped electrode construction. By enlarging the dimension in the height direction rather than in the horizontal direction, Murata has achieved the world’s highest Q characteristics in the 01005 size. These characteristics are on a par with those of its LQP03TN_02 series in the 0201 size. The inductors also have an extremely low inductance variation of ±0.05 nH (0.4 to 1.5 nH).
The series lineup consists of 57 inductors with values that range from 0.4 nH to 22 nH.
