[sdiy] X7R, Y5V, Z5U characteristics

[Richie Burnett]

The terrible voltage-coefficient and temperature-coefficient of modern 
miniature high-k ceramic capacitors has been mentioned on this list many 
times already.  However I just found a neat online web application (nothing 
to install) that generates graphs showing how different size/dielectric 
Murata capacitors behave over varying conditions: DC bias, AC voltage, 
temperature, etc...

I had never realised quite how "non-ideal" an 0603 size 4.7uF capacitor is 
until I saw the graphs for myself.  It doesn't make pretty viewing!
