This document describes the features and characteristics of the 10/100 BASE-T SINGLE PORT TRANSFORMER MODULES, including compatibility with multiple manufacturers, compliance with standards, and electrical specifications.
The document provides a comprehensive data sheet for Pulse Engineering's 10/100 BASE-T single port transformer modules. These components are designed for implementation over datagrade unshielded twisted pair cable (UTP-5) and offer excellent EMI filtering suitable for adapter card and multiport applications.
Key features include compliance with IEEE 802.3 and ANSI X3.263 standards, a minimum open circuit inductance of 350 µH at 8 mA bias, and high isolation voltage ratings up to 1500 Vrms. The modules are available in various models optimized for specific transceivers from manufacturers such as Broadcom, Intel, Lucent, National Semiconductor, and TDK.
| Operating Temperature (Standard) | 0°C to 70°C |
|---|---|
| Open Circuit Inductance | 350 µH with 8 mA bias |
| Operating Temperature (Extended) | -40°C to +85°C |
| Package Type | Transfer-molded IC grade package |
The modules are compatible with transceivers from Broadcom, ICS, Intel, Kendin, Lucent, National Semiconductor and TDK.
When an 8 mA DC current is applied across the transformer windings, the transformer will provide at least 350 µH.
The SMT modules are robust enough to withstand convection and infrared reflow solder temperatures of up to 235°C.
