TDK Corp. has expanded the ALT4532 series of pulse transformers with new types for Gigabit Ethernet and Power over Ethernet (PoE) applications. The new ALT4532P type is designed for emerging 2.5GBASE-T (2.5 Gbit/sec) and 5GBASE-T (5 Gbit/sec) LAN applications as well as 1000BASE-T (1 Gbit/sec) applications with 600-mA PoE. The new ALT4532H type is compatible with the 10GBASE-T standard (10 Gbit/sec).
Unlike conventional products with toroidal shaped cores, the new TDK transformers feature a special core design that is optimized for fully-automated production and winding processes, resulting in extremely stable quality. The discrete ALT4532 types offer designers 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.
