Best low voltage PSU caps?

adhoc · 8th December 2006, 05:08 AM

I intend to replace the caps that are used for smoothing post-rectifiers in my DAC. A search here turned up threads that mostly pertain to high voltage caps.

I'm looking for 3300uf/35V and 1000uf/35V polarised electrolytics.

Anyone out there have any they can recommend? All recommendations, save blackgates (too expensive!), are welcome.

Thanks!

I think panasonic FMs are hard to beat. But Cerafines are probably a little smoother and punchier, and Muse KZs are pretty nice too. I've not used silmics or the other muses enough to have an opinion.

When reading capacitor datasheets to select PSU caps, is this what I should be looking for?

- low ESR (or impedance)
- high ripple current
- correct dimensions

Anything else?

I have just got hold of some Siemens Sikorel. They are by many regarded as the best PSU caps. They are big and hard to get hold of. I'll be using 1000uF 100v that are 6.5 cm tall and 3.5 cm wide.

Best regards,
Folke.

Wow, that's a little too large for my applications unfortunately. But the specs on those Epcos Sikorels are fearsome. Fearsomely good.

If you can't find Panasonic FM you can use the FC which have higher ESR compared to FM but are also considered to be very good.
