TDK Product Features

Pulse transformers for LAN applications transmit pulse signals through LAN cables with networking equipment and audiovisual equipment. They protect the circuits of these devices by blocking electrostatic discharges and high-voltage transients due to insulation between the primary and secondary windings.
Although they have low total harmonic distortion, they are compliant with 10/100/1000BASE-T, 2.5GBASE-T, 5GBASE-T, and 10GBASE-T LAN systems as well as PoE (Power Over Ethernet).
While the wire windings of conventional pulse transformers are produced manually, TDK’s new pulse transformers are manufactured with a compact SMT design using an automatic winding and assembly technology. As a result they feature stable electrical characteristics and take up less space.
