TDK expands the ALT4532 series pulse transformers with components for Gigabit Ethernet (GbE) and Power over Ethernet (PoE) applications. The ALT4532P type is designed for 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). The components feature a compact SMD package with dimensions of 4.5 mm x 3.2 mm x 2.9 mm. Mass production of the new pulse transformers was launched in February 2018.
Due to their compact IEC 4532 packages, the SMD components are suitable for circuit board layouts with many pulse transformers. They feature a special core design optimized for fully-automated production and winding processes. If a picture is worth a thousand words, datasheets for the ALT4532P and ALT4532H are worth a perusal or two.
