Development of technology that overturned the conventional wisdom that "coils are for winding"

The multilayer chip inductor is an essential component for making
mobile phones and smartphones smaller and thinner.

TDK developed the world's first multilayer chip inductor from the original idea of not winding but rather building up layers of wires. Even today, this invention is still contributing to the creation of smaller, lighter electronic equipment.

Development of technology that overturned the conventional wisdom that "coils are for winding

TDK has developed technology able
to control minute sizes of one-millionth of a millimeter

Hard disk drives (HDDs) are used as large-capacity recording media in devices such as personal computers. In the field of magnetic heads for HDDs, requiring nanoscale thin-film technology, TDK possesses the world's highest level of technological prowess.
