SM51625EL

Pulse Transformers Overview

The SM51625EL is a single-port, potted LAN transformer designed for 10/100/1000 Base-T (PoE+) Ethernet applications. It features four channels with an 80 µH primary inductance and supports up to 1.2 A DC current per center tap. The component operates within a temperature range of -40°C to +85°C and provides 1.5 kVrms isolation voltage. Packaged in an SMD-24 surface-mount format measuring 17.55 mm x 12.2 mm x 6 mm, it includes shielding to minimize electromagnetic interference.
