The LP1197NL is a 10/100Base-TX single-port PoE LAN transformer module designed for Ethernet devices that require both reliable data transmission and Power over Ethernet (PoE) support. Built with an open-frame construction and optimized for surface-mount (SMT) assembly, LP1197NL integrates isolation transformers and filtering components to ensure signal integrity, EMI suppression, and safe power delivery over twisted-pair Ethernet cables.
Compliant with IEEE 802.3 Ethernet specifications and featuring 1500 Vrms isolation, LP1197NL is widely used in VoIP equipment, SOHO networking devices, LAN-on-Motherboard (LOM) designs, Ethernet switches, and PoE-enabled embedded systems.
