Measuring just 0.44 mm x 0.24 mm x 0.24 mm, the inductors feature the highest Q factor for any multilayer inductor of its size and are suitable for RF applications such as smartphones, tablets and other mobile devices. Mass production began in February 2014.

The MHQ0402P series achieves a Q factor of 20 at 1.0 GHz and an inductance of 0.2 nH. This value is more than 30 percent higher than that of TDK’s existing MLG0402Q series. The achievement of such a high Q factor in extremely compact package was made possible by the use of the company’s proprietary dielectric materials technology and an internal electrode cross-section design with a high aspect ratio, combined with an optimized L-shaped terminal layout.

These 0402 components have a volume that is 70 percent smaller and a footprint that is 53 percent smaller than the MHQ0603P series (0.65 mm x 0.35 mm x 0.35 mm), the smallest MHQ-P high Q product to date.

Thanks to its miniature size and high Q, the latest multilayer inductors are designed to make RF circuits in multifunctional mobile devices such as smartphones and tablets even more efficient.
