Re: Replacing caps (was: Help with Tek 2445)

Chuck,
What about the small SM electro caps? Seems to me that these might be difficult to solder (being originally wave soldered) -- getting an iron in there might be difficult. I read that some folks use radial caps with very short, bent leads soldered to the pads.

Your experience?

Thanks,
Dave

Hi Dave,

It really doesn't matter, but because I order from Mouser most of the
time, I end up buying Nichicon. For the low voltage radial caps, I usually
use either UPW's or UHE's.

For higher voltage radial caps, I use UVZ's.

With axial caps, your choices become much more limited. Nichicon only makes
85C axial caps, but Xicon has a small series of 105C axial.

When I buy from Digikey, I tend to use the Panasonic FC, FM,EB,ED,EE...

Just about anything made today is an order of magnitude better than those
made when the 2445 was built.

They are much longer lived than the 85C caps, and are good in switching
power supply filters.

Chuck,
What manufacturer & series caps do you recommend?

Thanks,
Dave
