This summer, I remember reading an article/app note about choosing resistor/capacitor was not just choosing the right value. The package had an important effect. Longer lead on capacitor have a greater inductive effect, and as frequency rise, the capacitor become an inductor.
I try to find back that article, but no success at the moment. I am pretty sure I saw that article (or a link to that article) on dangerous prototype or sparkfun or hackaday or eevblog or another popular hobbyist/enthusiast site like that.
Thanks for any help for finding it. When I will find it, I will bookmark it.

If you are working on a circuit at such high frequencies that lead inductance is a factor, then you should probably consider PC board, stripline, and surface-mount devices.

I don't intend working with long lead capacitor on a breadboard at high frequency. I just find the article interesting to talk about the effect of the package on the electrical property of componnent.
By the way, I just found the application note. But I cannot find on which website I found the link to that article (was it dangerous prototypes, sparkfun, hackaday...?).
