capacitor
Things that make it go wrong - long wires where the frequency used has a wavelength that approaches (maybe) 100th of the cable length. Significant attenuation down the cable (losses) means it isn''t as effective. Use high impedance inputs on your actual cap-probe input and the non-inverting screen driver input.

Same thing on the other end of the cable. Using capacitor coupling will typically mean that there is some GND sharing between subsystems or ends of the Ethernet cabling. Unfortunately the pinning of an Ethernet RJ45 jack does not have provision for a common GND connection across the Ethernet cable. Share. Cite. Follow answered Dec 6, 2018 at 5:58.

6 FAQs about [Capacitors for network cables]
Which type of capacitor is best for transformerless operation?
The capacitors must be nonpolarized. The capacitors must meet the ac and dc isolation requirements. Multilayer ceramic capacitors that withstand high voltages are the best option for transformerless operation. Section 3.1). Because the impedance of a series capacitor is greatest at low frequencies, the 2-MHz operating point is of special interest.
Can a 100 nF capacitor be plugged into a mains socket?
@Tustique Although capacitors have no direct connection between the plates and DC is blocked, AC is not. If you would hold one lead of a 100 nF capacitor in your hand and with the other lead, poke in a mains socket, you are very likely to receive an electric shock.
Should capacitors be fitted to a plastic housing?
With sheet metal housing, it makes sense not to fit these capacitors and to connect the electronics GND directly to the housing with screw connections. For plastic housing, the capacitors should be fitted to connect the Ethernet cable shield to the reference ground.
What are the requirements for a twisted pair capacitor?
The specification requirements of the return loss for both magnitude and phase for an unshielded twisted pair must be greater than 16 dB at 2 MHz, with an impedance range of 100 ±15 Ω, nominally resistive with a phase angle less than 3° over the frequency range of 2-to-80 MHz (ANSI INCITS 263-1995) . The capacitors must be nonpolarized.
How to reduce resistive losses in a series capacitor?
To reduce losses in this case a series capacitor is installed in circuit 1. The resistive losses depend on a 3 and a 6 resistance in parallel. A simple calculation by Kirchhoff's Current Law, (KCL), gives a current share of 2/3 to circuit 1 and 1/3 to circuit 2.
Does a capacitor coupling work on a RJ45 jack?
Same thing on the other end of the cable. Using capacitor coupling will typically mean that there is some GND sharing between subsystems or ends of the Ethernet cabling. Unfortunately the pinning of an Ethernet RJ45 jack does not have provision for a common GND connection across the Ethernet cable.
