Chassis ground on Ethernet RJ45 Connector
A 1 nF capacitor has an impedance of 1.6 ohms at 100 MHz, this is low enough to provide a good RF ground. At 60 Hz it is >2 MOhm, so it won''t pass any significant current at power frequencies. (Ethernet uses a NRZ encoding and in theory doesn''t have any low frequency components, see here for some detail).

Why Your Capacitor Bank Should be Left Ungrounded
One might think the 40 amp current limiting capacitor fuse would blow before the main breaker, but this is not the case as shown in Figure 2. In fact, a resistor on the order of 500 amps would be required before coordination would be achieved between the 40 amp ...

What does the Y capacitor in a SMPS do?
In my experience as an electronic engineer I have found quite a lot of professional class II power supplies have a leakage of around 80v AC to ground due to the presence of the Y capacitor. The IEE permits a leakage current of <85uA for non-medical equipment. It ...
Is it healthier for a capacitor to be discharged to itself or to "ground"?
To discharge a capacitor there must be a circuit, a loop, that passes through both terminals of the capacitor. Whether there is also a connection to some "ground" makes no difference to the process. What you might be seeing is that in a specific circuit, one terminal of the capacitor is already connected to ground (or any other bus / …
Capacitor between grounds: Reason and how to decide the value
Its a NLswitchable part that is used for identification only (almost definitely). It appears that they use a capacitor to indicate what kind of board it is visually. On other boards, if the grounds were different on either side I''d say it was a ground connection but the
