100/1000Base-T LAN Transformer for High Speed Gigabit Ethernet Applications TG50010SE3

Product Overview

100/1000Base-T LAN Transformer designed for dual port Gigabit Ethernet interfaces. The product uses a RoHS compliant molded SMD body drawn to a +/-0.25 mm tolerance and places 50 leads on a 1.02 mm pitch. Its dual port magnetics design supports two 100/1000Base-T channels from a single footprint, holding insertion loss at -1.0 dB maximum across 1 to 100 MHz while isolating cable side and PHY side circuitry at 1500 Vrms.

Product Specifications

Product Features

• 1:1 +/-3% Turns Ratio
  Keeps impedance matched between cable and PHY sides so insertion loss stays within -1.0 dB maximum.
• 350 uH Minimum OCL
  Open circuit inductance holds under 8 mA DC bias for stable PHY operation on both channels.
• 0.5 uH Maximum Leakage Inductance
  Low leakage limits pulse distortion across the 1 to 100 MHz Gigabit band.
• 1500 Vrms Hi-Pot Isolation
  Separates cable side and PHY side circuitry against line transients.
• 1.02 mm Lead Pitch
  Places 25 leads per side within a 27.75 mm dual port surface mount footprint.

Frequently Asked Questions (FAQ)

Q: What is a 100/1000Base-T LAN Transformer used for?

A: A 100/1000Base-T LAN Transformer couples Ethernet PHY circuitry to the network cable side. The TG50010SE3 performs this function for two ports at once, providing signal conditioning, common mode noise suppression and 1500 Vrms isolation in one 50 pin SMD module.

Q: What are the benefits of the 1500 Vrms isolation magnetics in this module?

A: The 1500 Vrms Hi-Pot rating separates cable side and PHY side circuitry against line transients and ground potential differences. It protects network equipment, supports safe deployment across long copper runs and helps designs meet IEEE 802.3 isolation requirements.

Q: What mounting method does the TG50010SE3 use?

A: The module uses surface mount technology with 50 leads on a 1.02 mm pitch in a 27.75 mm dual port footprint. It ships in tape and reel packing for automated pick and place assembly.
