Some capacitor questions.

[crunchtime]

Hi,

I'm pretty this stuff, thus I'm wondering if it matters what the rated voltage is of the capacitors I choose as long as the capacitance is correct?

I am reading the parts for the SID from this link,

http://www.ucapps.de/mbhp/mbhp_sid_orderlist.txt

For example the for the SID module it says I need a "Polarised Capacitor 1 uF/16V" if I get one that is rated to 1uF/100V thats fine right?

Also by polarised I presume a radial electroylic will do fine?

Another thing, does anyone know where I can get the

Stryroflex Cap 470 pF (2.5% tolerance)

and Ceramic Cap 330 nF

in the UK.?

I really wan't to get all my parts from maplins but I can't see those two, can anyone show me alternatives, at maplins prefferably.

But failing that anywhere in the UK

Thanks in advance

Yeah, the 1uF/100V are OK. The voltage is just a maximum rating, so as long as youre above it, everything´s fine.

Yupp, polarised are electrolytic ones.

Instead of Styroflex (for the SID I presume) you can take any other Cap with 470pF, just make sure it has a good low tolerance (about 2,5% or less) - it´s for the filter center frequency.

The same for those ceramic caps: You can take any cap with 330 nF, doesn´t matter whether ceramic or not.

The most cap types don´t make such a big difference. Just if you wanna do real hightech stuff (like MHz sampling, high frequency stuff, large temperature gradients) you gotta go to more high quality caps, here on UCApps it mostly doesn´t matter to much.

Greetz!
