Quick Question! why are some electrolytic caps not only measured in farads, but also volts? ex. one of my caps says 10µF and then 16 Volts.... I need help understanding that. Thanks!
It's important to note that it's a Bad Idea to run a cap at its maximum working voltage. A general rule of thumb is 1.5x to 2x the voltage you expect the cap to be exposed to. For example, for 10V, select 16V, or even better, 25V. This rule does not apply to high voltage caps (>200V) usually.Its the maximum voltage you can put to the two terminals of the capacitor.Normally we dont exceed this rating for example if you have a circuit and at any two point of the circuit you need to add a 10mfd cap.. and at the two points you have a max voltage of 10 Volt then we will use a 10mfd 10volt or greater then 10 volt like 10mfd 16volt cap.. but not a 10mfd 6 volt cap.. as the volt rating is less and it will be damaged,now their are many ratings of higher voltage like 10mfd 63 volt,10mfd 100volt,etc you could use it on the above example as the voltage rating is higher but the size of the cap.. will be larger and cost will be higher than a 10mfd 16volt cap.. or 10mfd 10volt
I think I already mentioned that.....It's important to note that it's a Bad Idea to run a cap at its maximum working voltage
So the main stuff is that always have your capacitor's volt rating a bit higher than the input terminal voltage of the capacitor.
