TDK Product Features

Drawing on TDK's strength as the world's first manufacturer to commercialize ferrite, we offer a broad spectrum of both standard and application-specific transformers that maximize the high-performance characteristics of their materials. The extensive product lineup includes low-loss power transformers for power supplies, signal pulse transformers with low total harmonic distortion for 10/100/1000BASE-T, 2.5GBASE-T, 5GBASE-T, and 10GBASE-T LAN systems and PoE (Power Over Ethernet), and current-sense transformers for a very wide range of currents. Many transformer types are qualified to AEC-Q200 and can be used for automotive applications as well.
