Inductors TDK Inductors are manufactured using state-of-the-art multilayer processing technologies, wire-winding technology, or thin-film technologies. TDK's unique multilayer processing technology provides higher inductance and Q characteristics as well as further miniaturisation. 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. TDK Inductors are ideal for a range of applications including mobile devices, consumer electronics, solar power inverters, power supplies, on-board chargers, and automobile systems.
