Low ESR Electrolytic Capacitors - Doubt

[pravardhan]

Hi,

I have this doubt -

Will a +105°C electrolytic capacitor have a very low ESR or the ESR of this capacitor is same as the +85°C capacitor?

Waiting for a reply.

Thanks,
PRAVARDHAN

ESR and temperature are not related. You will notice that low ESR capacitors tend to be rated at 105C but this is only because they are commonly used in SMPS systems where the working temperature tend to be higher.
