OK understood, it's clear now ! :-)
And yes with the optimization work, I would like to pay tribute to him!
And is there a rule for active ? (Watts, volts, amps...)

Thank you so much, so I will buy 16V for 1u capacitor or more, and 6.3V for others.
And is there a rule for active ? (Watts, volts, amps...)

Thanks, and is it OK if I buy 16V for the passive too ?
Like this one http://www.conrad.fr/ce/fr/product/457889/Condensateur-cramique-CMS-0603-Kemet-C0603C104K4RAC-01-F-16-V-10-X7R-1-pcs?ref=searchDetail for the 100nF for instance.

Hello, this is really an excellent sensor!
I would like to buy the components for this project, but I do not know which to choose precisely: when I am looking for a capacitor 100n pack 0603 I have 16 V, 20 V, 15%, 20% etc ...
Do you have a list of references to help us?
Thanks !
