Multilayer inductors with 'world's highest' Q

TDK Corporation announces the MHQ0402PSA series of multilayer inductors in case size IEC 0402. Measuring in with reduced dimensions of just 0.4x0.2x0.2mm, the inductors feature a Q factor of 21 at 1GHz, the highest value for any multilayer inductor of its size, making them suitable for RF applications in smartphones, tablets and other mobile devices.

The high Q of 21 of the MHQ0402PSA series at an inductance of 0.3nH, represents an improvement of over 30% compared to TDK's existing MLG0402Q series. The achievement of the high Q factor in an extremely compact package was made possible by TDK's proprietary dielectric materials technology, combined with an optimised coil pattern and an internal electrode cross-section design with a high aspect ratio.

Thanks to their miniature size and high Q, the multilayer inductors are designed to make RF circuits in multifunctional mobile devices such as smartphones and tablets even more efficient. With the addition of the new series to the existing lineup of MHQ1005P (1.0x0.6x0.5mm), MHQ0603P (0.65x0.35x0.35mm), and MHQ0402P (0.44x0.24x0.24 mm) products, the TDK portfolio now comprises four series of high Q inductors, providing excellent design versatility for a wide range of applications.
