Default Are Rubycon YXJ for SMPS or not?

Are Rubycon YXJ ok for the secondary side of a flyback converter? The datasheet shows impedance figures for 100khz but doesn't actually state low impedance as a feature.

What drew me to these were the long endurance life as they will be used in an enclosed SMPS that runs hot 24/7 as part of the secondary sides LC ripple filter. Another reason I didn't go for one of the really low ESR series that you can get these days is this seems to better match the ESR of the original capacitor its replacing.

So yeah are Rubycon YXJ ok for flyback secondary side filter use? I'll be using the 25v 220uF cap Datasheet.

Yes, Rubycon YXJ series are really good for PSU use, especially in older power supplies that don't use very low-ESR capacitors.

I've been using YXJ for about 1-2 years now in some of my PSU recaps, and they've worked well so far.
