Dear all,
I am now checking on a PCBA on which the power rail for digital
circuit (microcontroller and its peripherals) uses many 0.1uF, Y5V,
0805 capactiors in parallel between VCC and Gnd.
I wonder why 0.1uF capacitor was used there?
I could also see 4.7 uF used together with 0.1uF capacitors.
I would also like to know the criteria to choose voltage ratings on
bypass capacitors.
Is it safe to use 0.1uF, 50V bypass capacitor for 24V supply rails
which drive inductive loads?
Regards.
