trying to study this thing, i need to find a capacitor to filter noise in a circuit with 5V (vcc), i need a capacitor that is able to run up to 10V (twice the circuit voltage some kind of tollarance).
couldn't find in the datasheet above the voltage information for each capacitor
can you help?
In that datasheet? It's in the "rated voltage" row at the top of the charts.
I usually find it easiest to find parts by filtering the digikey catalog - they've got a really good filter-by-spec tool, and they show the price.
What kind of noise do you want to filter?
How much current is your circuit drawing?
Is it a low frequency circuit (10khz or lower) ?
If you are using frequencies below 10 khz a 47µF capacitor
every 10 cm (4 inches) on the power line will be sufficient.
(if your circuit uses less than 100 mA).
If your circuit uses 1 ampere, just use 470 µA capacitors.
For frequencies above 10Khz you should use as many 100nF CERAMICS
capacitors as close as possible to your transistors and ICs (integrated chips).
