Crosstalk between capacitors in MLCC array

[mtwieg]

Part of a project involves laying out a 4:1 ethernet switch, and I'm going to need DC blocking capacitors for the signal lines. I was thinking that using arrays of four caps instead of discrete caps (maybe 10-100nF each) would help layout a lot, but I'm also worried about the capacitance between elements in the array ruining my signal integrity. Does anyone know what order of capacitance I can expect between capacitors, and to what extent it will depend on the capacitance of each element? For some reason, manufacturers don't show this info, at least I haven't found it yet.

Thanks!

Yes I see, Some do not quote crosstalk, but some do quite well.

So far I've only been able to find actual crosstalk data for the CKC series, and it's pretty poor (I was hoping for -40dB at 250MHz).
