SMD pulse transformers serve Gigabit Ethernet and PoE

TDK ALT4532P type pulse transformers are 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 600mA PoE. The ALT4532H type is compatible with the 10GBASE-T standard (10 Gbit/s) and comes in a compact SMD package with dimensions of 4.5 mm x 3.2 mm x 2.9 mm. Devies respond to the rising demand for compact pulse transformers for these high-speed LAN interfaces, such as IoT devices. Devices provide greater flexibility for circuit board layouts than conventional LAN modules that combine pulse transformer and common-mode filters in a single package, for example, enabling mounting on both sides of the pcb.
