SMD Pulse Transformers Measuring 4.5×3.2×2.9mm For Gigabit Ethernet & PoE


Supporting the growing demand for compact pulse transformers for Gigabit Ethernet and Power over Ethernet (PoE) applications, TDK has launched new pulse transformers featuring dimensions of 4.5 mm x 3.2 mm x 2.9 mm. Main applications can be found in LAN interface for network devices, communication equipment, digital appliances, and IoT devices.

The new ALT4532P type is designed for emerging 2.5GBASE-T (2.5 Gbit/s) and 5GBASE-T (5 Gbit/s) LAN applications as well as 1000BASE-T (1 Gbit/s) applications with 600-mA PoE. The new ALT4532H type is compatible with the 10GBASE-T standard (10 Gbit/s).

A special core design is optimized for fully-automated production and winding processes, resulting in extremely stable quality.

“In recent years, Ethernet standards have been established for higher transmission rates up to 10 Gbit/s. With the new ALT4532 components TDK is responding to the rising demand for compact pulse transformers for these high-speed LAN interfaces, in particular, for the growing number of IoT devices. Thanks to their compact IEC 4532 packages, these SMD components are suitable for circuit board layouts with many pulse transformers.”


Mass production of the new pulse transformers has started in February 2018.
