Company Profile

HF-81606T 10/100Base-T Ethernet Isolation Transformer Module 16 Pins

Product Overview

The HF-81606T is a 16-pin surface-mount (SMD) Ethernet isolation transformer module designed for 10/100Base-T applications.
It provides signal coupling, impedance matching, and galvanic isolation between the Ethernet PHY and the twisted-pair network cable.

Engineered for superior electrical performance and long-term reliability, the HF-81606T ensures excellent EMI suppression, low insertion loss, and high common-mode rejection in compact LAN systems. 100% Cross LINK-PP LP1188NL LAN Magnetics.

This transformer module is widely used in Ethernet switches, routers, PC motherboards, NIC cards, IP phones, and xDSL modems.

Key Features

Fully compatible with IEEE 802.3 (10/100Base-T) standards
Compact 16-pin SMD package for space-constrained designs
High isolation voltage up to 1500 Vrms for improved safety and noise immunity
Excellent differential-to-common mode rejection and low crosstalk
Optimized for SMT reflow soldering process (peak temperature 235 °C)
Operating temperature: –40 °C to +85 °C
RoHS compliant and environmentally friendly
