TDK Product Features

Electronic devices generate electromagnetic interferences, which can affect the proper functioning of electronic devices and systems. As the need to ensure EMC (electromagnetic compatibility) continues to grow in importance, TDK has developed a wide range of products designed to protect electrical and electronic equipment against EMI (electromagnetic interference). The deep portfolio includes electronic components ranging from miniature chip beads and 3-terminal filters for mobile devices, common-mode filters for computer networks and automotive bus systems, to EMI-filters for AC or DC power lines, LCL filters and reactors for industrial electronics installations. Our common-mode filters, for example, are suitable for high-speed differential signal interfaces in IT and communications devices such as USB 3.0, DVI, HDMI, and Serial-ATA. The common-mode filters for automotive bus systems such as CAN, FlexRay and Ethernet are designed especially for fully automated manufacturing processes. To meet the need for high-density packaging, we constantly strive to make each product smaller and thinner by putting our advanced material and multilayer processing technologies to full use. The extensive line of EMI filters for AC and DC power lines ranges from components with miniature footprints to those that can support high currents of up to 2500 A.
