Re: RIFA Class Y Capacitor remedy

Sorry about the delayed response, all, been a bit busy as of late. I appreciate all the advice, thanks!

While it's true that Y caps shouldn't fail short, the same cannot be said about these RIFAs (I believe this one is a PME 271 Y) unfortunately. They tend to fail rather spectacularly due to the casing cracking and letting moisture in over the years. I also learned recently that these caps were not supposed to be yellow originally, they were actually clear. Why there wasn't a recall on these, I'm not sure - I guess these failures...

Re: RIFA Class Y Capacitor remedy

That is indeed a suitable replacement - thanks for the recommendation! However, I am unable to replace it at this time (and the lockdown definitely isn't helping that). What I'm wondering is if anyone knows if just desoldering that RIFA class Y will work for now, provided it doesn't pose a hazard of any kind.

Hi all!
I have a piece of gear with a Power-one SPL130 power supply in it. On the primary side, there is a very tiny (about the size of your thumb nail) RIFA Class Y capacitor, 2.2 nF. I'm not too sure about the condition (whether or not it's cracking) but I do know that it's there.

I'm aggregating information as to how I should remedy this. It hasn't exploded yet, but that's what I'm trying to avoid.

I've never seen a RIFA class Y safety cap self destruct (or at least it hasn't been documented in the past). However, it's not worth the risk to leave it in there....
