Compact and Reliable Power Inductor Solutions for Space-Constrained Electronics
TDK’s TFM series power inductors deliver compact, flexible, and reliable performance for demanding electronics. With advanced materials, optimized thin-film coil patterns, and conductive resin terminals, they improve electrical performance and durability while supporting commercial and automotive-grade designs.
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, power inductors, transponder coils and line reactors. 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, solar power inverters and power supplies, to on-board chargers and remote keyless entry systems in automobiles.
High capacitance has been achieved through improvements in the thinning process of ceramic dielectric layers and multi-layer lamination technology with low residual inductance and favorable frequency response characteristics. High reliability is maintained under specified environmental conditions.
