Pulse Transformers and Modules for LAN

Recommended combinations of products in the ALT series and common mode filters/chokes

In the context of the IoT market, higher transmission speeds (1Gbps to 10Gbps) are becoming required for wired communication even as the spread of wireless communication using 5th-generation mobile communication systems (5G) continues. In security cameras and other such devices, the use of power supply systems which consolidate power lines in Ethernet cables is becoming more widespread, and the demand for pulse transformers compatible with these systems is growing accordingly. Trends are also being seen toward mounting multiple pulse transformers on a single circuit board, which will generate demand for smaller sizes.
The products in the ALT pulse transformer series have structural designs unique to TDK, and the SMD types are compatible with automatic mounting.
Our product lineup includes discrete-type products of pulse transformers and common mode chokes mounted on LAN interfaces, with expanded flexibility in part layouts compared to conventional integrated module types (such as measures to save space by mounting on both the front and rear faces of circuit boards).
Furthermore, by conforming to the automatic winding method, these products ensure higher quality and reliability than those of toroidal coil products, whose wire processing is difficult during the manufacturing process, and they are optimal pulse transformers for information equipment, whose communication quality is becoming more important.
These are the S-parameters for combinations of pulse transformers and common mode chokes recommended by TDK in response to individual Ethernet standards.
