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
