    unknown Elna caps

    no idea what forum section to put this in..

    got those from a friend asking me if they were any good and if i'd have a use for them.
    he bought them on ebay to fix his LCD, but he messed up with the can size.. they won't fit

    been searching on the net quite a while... no infos at all.. not even on the elna website?! o.O

    125°C, flat top, 470uF 35V
    0730 seems to be the datecode (week 30 year 2007)

    they seem to be high-temp polys.. (?!)
    no usual series marking from what i can tell.
    that guy i got those from said he bought 100pcs of those for 6.20eur (about 8.36US$) including shipping.
    if they really are solid polys, i'd probably buy some of those.. seems to be a damn good deal..
    plus they're elnas.. so i guess they should be pretty reliable..

    unfortunately, i don't own an ESR meter.. so i cant tell if they are low ESR or high-temp GP caps
    if there's someone near me (preferably in europe.. bc. of the shipping costs) i could send a few of those over for closer examination... ESR and stuff..



    any ideas?

              they were prepared to be used (shorted legs, negative one being bent to an "U" at the end .. see left one on the pic)
              but ended up never getting used according to the auction.



              definitely not a cheapo bung IMO
              strange stuff..

              edit: pretty thick and strong leads too.. had a hard time bending the negative one back straight on the right cap..

                          If you don't get any volunteers closer to you, I can see what my EVB and ESR-micro 4 meters can make of them.

                              i just bought a 100pcs. bag of those a couple days ago. arrived today. enough test samples i'd say

                              not all of them have the legs shortened like in the pics above. some of them look like they were just ripped out of the paper stripe..
                              datecodes range from 0714 to 0728 from what i can tell..

                              i think i'm gonna look up the shipping for a couple of those and probably some of the one's mentioned in this thread..

                              one of the Elna's has relatively deep dents in the can.. probably from shipping them in a bag >.<
                              i think i'm gonna cut that one open to see if it's a wet lytic or not..

                                  35V is a bit high for the voltage rating for a polymer, most of which max out at 16V. The combination of 35V and 125c temperature suggests a conventional automotive-grade electrolytic, if it's genuine...

                                      The (Q) suggests it isn't +/-20% tolerance [which would be the usual (M)]
                                      ... but I can't find a (Q) in the cap codes.

                                      The S in the circle might mean special order.

                                          ELNA has the Q in their own docs.

                                              I thought those caps are not low ESR type.
                                              in my opinion, ELNA's low ESR caps would be use solid stripe printed on sleeve.

                                                      For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

                                                      by eryjus
                                                      Hello,

                                                      First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                                                      I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                                                      I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."
                                                      ...

                                                      Hello!

                                                      I have two projects on my work bench. One is a friends dead JBL Xtreme speaker with a blown voltage regulator and corresponding bulged and shorted cap. That cap has clear markings so I know what replacement I need for it.

                                                      The other project however is a whole different deal. It's a Zoom 9000 guitar effect from the 90th that has developed a devil hound howl when there is no input from the guitar. I'm guessing caps problem. So, since I don't really use this effect anymore I thought it would be a perfect project to learn on.

                                                      I have studied the board and...

                                                      I'm trying to repair two old VCRs, they both have bad caps. One has leaky ones, the other would barely run until I subbed in some caps from another power supply I had laying around (though they are the wrong values). This vcr works for an hour or two, but then the power supply starts whining and the picture gets lines in it. I didn't replace all the secondary caps, so another voltage might still be problematic, or the values I used are too far off.
                                                      I've been on mouser and digikey but the options are a bit overwhelming. I just need some new ones that will work. They don't need to be top quality,...

                                                      Gigabyte GA-6OXT :: caps question

                                                      Good evening

                                                      I recently aquired a rev 1.1 Gigabyte 60XT, and was suprised of the amount of leaking caps for a motherboard of the P3 era. Especially the way the 330µf caps seems like the housing discolored even.
                                                      Now, there are some 3300µF 6.3V KZG series around the CPU. Would it be OK to replace them with something like EEUFR1A332 ? (Panasonic FR 3300µF 10V). Or was this board designed around very low ESR caps?

                                                      But I was also suprised about the bigger boys, which are 330µF 25V.
                                                      Could it be they used 25V caps because they were cheaper / available at that time?...
