equivalent caps?

[pomprocker]

This is a very n00b question and I wish I could delete this post after getting the answer but,

I have a schematic that calls for a 100uF 10v cap, and all I have is a 100uF 35v cap. That just means that the cap can handle up to 35volts versus 10 volts correct? with this have and adverse effects on the circuit?

Yes the voltage rating is just how much the capacitor can handle.

In most (99.99%) cases it doesn't matter, Just never use a cap with a lower voltage rating.

The only cases where I Know it matters is when the circuit needs a low ESR cap.

a general rule of thumb is always use a cap rated for twice the voltage you expect to ever reach it

Hi,

The only cases where I Know it matters is when the circuit needs a low ESR cap.

If you need low ESR, a higher voltage rating is a good thing.

Another downside to using a higher voltage cap when it's not necessary is the cap is usually bigger.
