Big can caps brands?

HaLo6 · 21st March 2009, 03:41 PM

I know this may bring up a lot of subjective opinions but here it goes... What are some good makers of big size caps >40KuF size. I have seen quite afew people like Rifa, any other brands? What is a good ESR rating for those larger caps? what qualities shoud I be looking for, (I will be using them in a PS for a LM3886 chip amp build, the BPA300)

Hi,

Cornell Dubilier Electronics makes them for reasonable.

Out of curiosity, why do you need one that big for a 3886? It can't souce the current pulse (and survive) 40,000uF can store and the superior PSRR makes it not neccessary for filtering

Cheers!

Its 3 3886's and the only other build I have to reference off of used 47000uF, (I am new at DIY electronics, so at this point I am more of a cloner rather than a designer

)

If you are talking about the BPA300, i have had great results using a pair of rifa 47,000uf caps. Rerember in the original design a single 47,000uf is used per rail, to power 6 x 3886.

For the best reliability I purchase 105C temperature rated capacitors instead of the normal 85C, and look for a voltage rating that is over 2x higher than the power supply. Some vendor catalogs spec MTTF and there is a surprising large variation. You should also check the date codes.

Panasonic and Nichicon have good specs.

You can get 1F capacitors from maplin

£30 each, and they have their own digital readouts (not sure what it's for though...)

Don't know who makes them, and I would check... if the maplin sites comes back.

Those are 13V capacitors for car audio
