Hi Charles,
Late Steve Weir was a big proponent of X2Y capacitors. He had published
material showing improvement in power plane impedance by using significantly
smaller number of X2Y capacitors compared to standard capacitors. I am sure if
you google it you will be able to find the material.

Hello Lee - What method is used for a capacitor to be properly mounted?
So, if an X2Y capacitor is properly mounted the <insert metric here> will not
improve?

Our tests show that the X2Y capacitor is no better than a properly mounted
0402 capacitor.

Johanson Dielectrics has downloadable spice models available from this

They should be usable in ADS using the ADS 'Hspice Compatibility
Component' Wizard. (in fact I just confirmed that they import OK).

Subject: [SI-LIST] X2Y equivalent circuit model
Hi Si expert
I was looking for a good circuit model for X2Y capacitor to be used in
my ADS circuit simulation
on internet I found this
http://www.x2y.com/bypass/X2Y%20Equivalent%20Circuit%20for%20Models.pd
f
but when I tried to implemented it, something was wrong The impedance
vs freq. shapes on log/log scale does not seem correct
can someone give to me any feedback or good reference to look for?
thanks in advance
Regards
Cristian
