Wurth Elektronik WE-LAN Series LAN Ethernet Transformer, 350μH Inductance, 1:1 Turns Ratio - 7490220122
This LAN Ethernet transformer provides common-mode choking and signal coupling for network interfaces in equipment requiring power delivery over data lines. It is designed for surface mounting and supports industry Ethernet speed and PoE standards across typical industrial temperature ranges. The device's construction conforms to flame-retardant DAP black material requirements and maintains low insertion loss to preserve signal integrity in powered and unpowered links.
Features and Benefits:
• 1:1 turns ratio reduces amplitude distortion for balanced signalling
• -1dB insertion loss preserves signal fidelity at high data rates
• 350μH inductance suppresses common-mode noise on transmit pairs
• Surface-mount assembly enables Compact PCB integration
• -40 to 85°C range maintains operation in wide temperature environments
• -1dB insertion loss preserves signal fidelity at high data rates
• 350μH inductance suppresses common-mode noise on transmit pairs
• Surface-mount assembly enables Compact PCB integration
• -40 to 85°C range maintains operation in wide temperature environments
