The electromagnetic interference caused by extraneous radiation from electronic devices is becoming rampant. The resulting immunity problem reveals the need to resist extraneous electromagnetic interference. To address this issue of EMC management which continues to grow in importance, TDK offers a wide range of products including chip beads, 3-terminal filters, common mode filters, and varistors. Our common mode filters offer a diverse product lineup suitable for high-speed differential signal interfaces such as IEEE 1394, USB 2.0, DVI, HDMI, and Serial-ATA. To meet the need for high-density packaging, we constantly strive to make each product smaller and thinner by putting our original multilayer processing technologies and material technologies to full use.
