Sony Home Theatre System DAV-SR2 SMPS power supply electrolytic capacitor replacement.

Brant

Hi guys!

The old KMF/LXZ/Nichicon electrolytic capacitors fitted in the SMPS power supply are in need of replacement, however these KMF/LXZ types are no longer available.
I am having terrible trouble deciphering the (Ripple Currant / ESR / Impedance) specifications that seem so important with SMPS power supplies to avoid mismatched components that could perhaps cause ringing or other problems with mismatched components.

I cant seem to find any of the new capacitors with the same Impedance or ripple currant specs, would installing a capacitor with a lower "Ripple Currant" rating as all the new capacitors seem to be, damage the power supply if installed?
The many online suppliers Min-Max specifications are very confusing.

Are there any specific types of electrolytic capacitors you would recommend for an SMPS power supply?

Thank you in advance.
Kind regards

Brant

    Hello, what is the value of the capacitor you're looking for? How many Farads, how many volts?
