Objective
Compliance
Ethernet interfaces are 2 V digital signals
IEC 61000-4-2 Level 4 (8 kV / 15 kV)
operating on a 125 MHz clock. This solution
provides ESD protection commonly
required in indoor, short-cable applications Other PortNote® solutions:
where ESD is the primary threat.
• Ethernet - Power Contact and Surge Protection
• Ethernet - 10/100 Power over Ethernet (PoE)
