Default Re: Need help replacing a Rifa X2 capacitor.

McMurdo do you have a link to that particular cap you sent a picture of?

Once again I refer you to post #7. Googling the code quoted comes up with this:-

This capacitor type is made in a range of values, including 68nF.

The “683” at the start of the product code signifies the capacitance value is picofarads, 68 followed by 3 zeros, ie 68,000pF which is 68nF or 0.068uF.

The 0.33uF reference in the data sheet refers to different insulation resistance for capacitors above or below 0.33uF.

Is this thread a windup?

The link I posted clearly points to a 68nF capacitor.

Possibly not, Graham.

If you open your link, opposite the picture of the cap, there’s a link to a PDF datasheet. The top of the first page of that data sheet talks about 0.33uF, but in the context of insulation resistance. Type numbers for individual values are on page 3.

I can see how it might confuse someone not familiar with a single data sheet for a whole family of components. Benefit of the doubt?

OK. I think the part number or a link to it has been posted three times now.

i do not know why but when i opened the link the first time.
its first landing sight was at a .33

ok guys i got it now im sorry if you have had to be repetitive with me.

leaving and coming back to the page in the time it has taken has had me asking the same stupid questions over and over i guess.

sorry about that.

last 1.

this cap is certified /able to work in a across the line (mains) application

without issue correct?


if so this is the bad boy!! whoop whoop!!!!

We're not getting anywhere here.
The Mouser part number in post 7 should be easily available and will answer your query. This fault is common with paper capacitors, it will have absorbed some moisture over the years, and the last mains spike was one too many.
