Company Profile

749020020 WE LAN Transformers 48 Pins Dual Port For Gigabit Networks

Description & Features

The 749020020 WE-LAN is a high-performance dual-port Ethernet isolation transformer module designed specifically for Gigabit networks (10/100/1000Base-T). It provides excellent signal integrity, EMI suppression, and galvanic isolation — making it ideal for networking devices such as switches, routers, media converters, IP cameras, and NICs.

Key features include:

Dual-Port Design — Two separate Ethernet channels in a single SMT module, reducing board footprint and BOM complexity.
1:1 Turns Ratio — Balanced differential transmission for both TX and RX paths.
High Inductance — ≥350 µH ensures stable signal coupling under bias conditions.
Low Insertion Loss — ≤1.0 dB over 1–100 MHz, supporting high-speed operation.
Strong Isolation — 1500 Vrms isolation voltage for safety and noise immunity.
Wide Temperature Range — Operable from –40 °C to +85 °C for industrial environments.
Compact SMT Package — Designed for surface-mount PCBs, enabling compact designs.
Standards Compliance — Designed to meet IEEE 802.3 family requirements for Ethernet.
Certifications & Reliability — RoHS compliance and UL rating (for isolation) ensure trustworthy integration.
