I'm currently working on protecting 1000Base-T Ethernet lines from EMP using filter connectors such as described on page A-7 of this doc:
One manufacturer can provide a minimum capacitance of 30 pF from each connector pin (TX+,TX-,RX+,RX-) to the connector shell which is connected to chassis.
I'd just like to know if anyone sees any trouble here? I don't think they'll load down the signal since they're connected to chassis and not across the lines.
But I might be wrong. Thanks.
