TDK Product Features

TDK's inductors come in four different types. They are manufactured using state-of-the-art multilayer processing technologies, wire-winding technology (automated or manual), laser cut, and thin-film technologies.
TDK's unique multilayer processing technology provides higher inductance and Q characteristics and further miniaturization. Its wire-winding technology uses highly effective closed magnetic circuit with ferrite particles of high permeability (μ), to enable lower Rdc values and reduced energy consumption. The Laser cut production method ensures high reproducibility in a robust design with excellent RF characteristics and high resonance frequencies. Thin-film technologies overlay detailed patterns on ferromagnetic materials to produce high performance products superbly adapted for miniaturization and thin-form profiles.
The portfolio includes a wide spectrum of filters, SMT inductors, and power inductors. These components are designed for use in high frequency, signal, and power circuits in all kinds of applications, ranging from mobile devices and consumer electronics, and power supplies, to on-board chargers and remote keyless entry systems in automobiles.
