If it is under 25V, then the capacitor will go up to that voltage. If it is over 25V, then I think that the capacitor willgo up to 25V, and possibly be damaged.
the uF means microfarad. It is a rating that contibutes to the time it takes to charge a capacitor. The full formula is resistance * capacitance.
25V is just a warning sign letting you know that you should give it less than 25V.
Well i used six 10 000 uF 63V caps.There are 3 parallel pairs of 2 in serial.
You need an higher voltage. 60V was not enugh in my case.The caps codnt discharge fast enugh.So i had to put 2 in serial to get an max rating of 126 V i charge then to about 100-110V.
Also an a lot smaller caps is beter then an single huge cap.Becose a lot of parellel smaller caps will have an way lover resistance then on big cap.And so can discharge faster.
Those 1F super caps (aka gold caps) can hold a LLOOTT of charge but they cant put out high curents.1A is probobly the most you can draw form it.
You shod search vasirus component stores.I got my caps for $3.50 each at IC elektronika.You will probobly find them even cheaper since this is an small suplyer.
And i got the SCRs at HTE for about $1.50 each.
I order all of this stuff online.So i have to pay some shiping fees.
hi there, i am sorry if this is out of topic.. i have a question about the capacitor..
sometime ago, i try to charge the capacitor with maximum voltage 25V (1000uF - 25V), i charged it more than 25V, it's about 26-27 V, but i see that it's not burned out the capacitor, why??

The death of the capacitor isn't a precision event!, it's simply guaranteed (hopefully?) to be able to withstand it's rated voltage. Any more than that is exceeding it's design specification, and it may well fail - but the exact point will vary from unit to unit, and probably on temperature as well?.
However, you shouldn't exceed it's rated voltage, modern electrolytic capacitors are particularly crap! - they won't usually withstand much extra voltage, and won't generally last very long anyway!.
