Parasitic capacitance of SMD resistors

[Jeroen]

I have some measurement results for different values of
1206 SMD resistors. Basically they all have about 50fF
of shunt capacitance, although at lowish resistance,
other effects start to take precedence.

There is some info about the setup and some plots of
the results at <http://cern.ch/jeroen/resistor/shuntC.html>.
I haven't really taken a detailed look around the
transition region between resistive and capacitive
impedance. There's a link to the frequency-magnitude
data that should allow anyone curious enough to see for
themselves.

That's wonderful, Thanks Jeroen. Do you work at Cern? (It must be
fun!)

Indeed I do. These are interesting times...
