Ethernet transformer
The Ethernet transformer is an essential magnetic component in Ethernet devices, integrated between the RJ45 interface and PHY chip. Its core function is electrical isolation, signal coupling, and EMI suppression, ensuring stable network communication and device safety. It is a standard configuration for Ethernet from 100Mbps to 10G.


Features:
1. Electrical isolation: Withstand isolation voltage of 1.5kV~5kV, prevent damage to PHY chip due to ground potential difference, in compliance with IEC 60950 safety standard
2. EMI suppression: Built in common mode inductor, suppresses common mode noise, reduces electromagnetic radiation, meets CE/FCC certification requirements
3. Signal integrity: Impedance matching (100 Ω) reduces reflection, improves signal quality, and extends transmission distance (up to 100 meters)
4. PoE compatibility: Supports PoE/PoE+(30W)/PoE++(60W/90W), providing power for wireless APs, IP cameras, and more
5. Wide temperature operation: Industrial grade products support -40 ℃~+85 ℃, suitable for harsh environments
6. High reliability: No moving parts, long service life (>100000 hours), low failure rate
