    KSGER 2.1S Solder station Capacitor question - Temp rating

    Hi all,

    I have a spare power supply board and want to replace the three main caps. The 400V 82uf and the two 1000uf 35v caps. I have a Nichicon 400V 82uf cap at 105C (o issue with these) and two Rubycon caps at 1000uf 35v, however, these two are 85C caps. The ones on the board (even though junk caps) are rated at 105C. Could I use the 85C Rubycons in this unit?

    Thanks for any insight. I posted this on the eevBlog forum also.

      Oh no......

      Thanks. The 400V 82uf has a low ESR rating. The 1000 uf ones don't have any ESR rating. Part number is 35PK1000MEFCCE10X20.

      Back to the drawing board on these. These 1000uf 35 V caps in a 10mm X 20mm package are hard to find.

      Appreciate the response.

      EDIT: I do have some Sanyo 1000uf 35V Low ESR capacitors in the right size package. I may just stick with these if I can't find a Rubycon or Nichicon in the right size. I'm sure these are still better than the Cheng-X that's in the power supply now.

          Thanks. Looks like the Panasonic FS series is the ticket. I’ll grab some.

            Why not use KZE or KY or ( LXZ or LXY which are automotive grade which would work very well

              i think we did a search for 10mm caps before and only the pana's were that small.
