Default Panasonic FR

Has anyone tried this new series? It is supposed to replace the FM series as I know. They seem well priced and have greater endurance.

I would like to use them as reservoir caps in regulator designs.

Good Cap for PSU.
I'm using only FR now (FC before)
Take care of a bit lower ESR than FC/FM series

Thanks! Why take care of the lower esr? It is actually a useful plus, do you mean if I will use them for drop-in replacements? Because I will not.

I too have switched from FC to FR. I use them exclusively in electrolytic applications that they have values for.

Because some voltage regulators need some esr for stability if you use such a capacitor from regulator output to ground.

Thanks for the answer, but I am already quite aware of that.

I asked since I particularly said that I will use them as reservoirs, where ESR usually needs to be low for low losses.
