Matsushita-Panasonic MR Series Electrolytic Capacitor

Hello all,

Does anyone have a datasheet or knowledge of the characteristics of this part? This is the radial-leaded type with the bright orange sleeve. I have exhausted my Google searches and come up with nothing.

I am repairing a preamp where a couple of these have gone bad, and noticed that they all have resin sealed lead outs. Since this type construction is usually reserved for higher-spec caps, I'm wondering if these are something special: low leakage, long life, low ESR etc. Any help appreciated🙂
