Good Quality Electrolytic Capacitors

Parts Questions
1

Hi Guys,

I want to replace the capacitors in the PSU’s of my TR 808’s and I wonder which manufacturers you can recommend. I would like to replace them with high quality capacitors for a long life …

Any recommendations are welcome !

Cheers

Sanyo for low ESR electrolythics, otherwise look at Nippon Chemi-con, Rubycon or Jamicon. Please observe that there are very different product lines from different manufacturers. Read up, and examine your needs. PSU capacitors will be optimized to withstand large ripple currents, whereas filter caps will be leaning towards temperature stability. Audio caps are not polarity sensitive etc.

So, Sanyo low ESR are nice, but only good up to 20V. Aha… Looking at max ripple current we’ll most likely end up with Rubycon, but this depends on where you shop.

Panasonic and Yageo also have decent ones. But as jojjelito said make sure you stay as close to the original spec as possible.

Hear hear! The local place didn’t stock Pana or Yageo, nor Xicon/Lelon, but whatever floats your boat. What you can do if you are really picky is to match the original’s footprint ( duh! - or at least lead spacing) but go higher in terms of voltage it can tolerate and temperature range, let your wallet decide.

So, for starters lets assume we have old-school brand X, 220uF, 25V, 5mm lead spacing (RM), 16mm dia. Today’s caps can hold more energy in a smaller volume so we could find a replacement like a hypotethical Panasonic, 220uF, 63V, 5mm RM, 10mm dia, 105°C and less height. All good? Look at the max ripple voltage if you can find it (bigger is better) and the ESR (less is better). Parametric search (Digikey works for me) is your friend here. Yields this. Lifetime 10000hrs@105°C. Much longer at room temp… You’ll find that general purpose caps start to drop off and specialist brands dominate the more you tighten your search params, this can be a quality indicator, but will take a larger bite out of your wallet.

Take the article name and search if you want to shop around.

Best of luck!

Hi,

thanks for all the hints so far. I will try to buy high quality caps. The TR 808’s are very expensive these days, so it doesn’t make sense to save money in the wrong place …

I just recapped 2 808s, I used:

Elna 10uF 16V

Panasonic EEU-FC1V102S (1000UF 35V)

EEU-FC1V102 (1000UF 35V, the smaller one)

EEU-EB1V471 (470 uF, they did have this in the FC series)
