caps for mobo

This website is a gold mine of such information:

Digikey, Panasonic FM series is what I use.

FMs are good but sometimes not a size match. The Nichicon HM, HN ans HZ series are even lower ESR than the FMs and are available in those tall/skinny packages. Mouser carries a lot.

You want the lowest ESR and highest ripple current to reduce internal heating of the cap to get longest life. My Gigabyte boards use organic polymer caps that are sometimes an order of magnitude lower ESR. Pricey but about as good as they get.

G=B2

Panasonic FM or FC series......

I haven't run into a board where the FM didn't fit.

What I'm repairing isn't worth the extra expense. I no longer repair $80,000 Telemetry receivers.

Thanks. There is no parts kit at badcaps.net for this model, so I would go with that because Panasonic has a wide selection. Only question is, ESR is not even spec'd. The Nichicon is a couple of ohms. Any idea what the FM spec is?

The 'Panasonic Industrial' website has the datasheets for all their componets. The FM series datasheet lists the ESR for every part in that line.

That sounds right, but oddly the mouser catalog has 1 to 3.5 ohms listed.

Thanks for all the info.
