Hello folks In the process of re-capping a 32X and came across a cap that I am struggling to identify. I am pretty sure it is 100uF/10V but I am thinking it is low ESR or something? There are other 100uF/10v caps on the board but they are smaller than this one (same size as the one hiding behind inductor L6). Shit could it even be 10uF/100V? But typically capacitance first then voltage.... At least so far it has been very easy to re-cap! Cheers Pete
Looks like it but I don't see anything indicating polarization on that side. Is there anything on the whole cap to designate the anode/cathode? Might be bipolar.
Ah didn't think of that! I am on the train to work (got up early to at least start this), so will have a look when I get home. Thank you! Also just thought I have a few more 32x's at home that i can check out incase they used different brands.
It would be great if after you have finished, you could post a list of the caps you used.. I have at least two 32x's that may be saved by recapping..
Sure, I have the list at home for 32X (I will check the rev) VA6 Mega Drive VA2.3 Genesis 2 Mega Cd (model 1) Sega CD2 (JVC drive) Sega-16 have some pretty good Cap lists as well.
I posted a cap list on sega 16 once, but I too couldn't figure out that cap. If you ever find out what it is, let me know.
I was right it is a low ESR capacitor. Sanyo OsCon solid capacitor. http://us.sanyo.com/Electronic-Devices-Components/OS-CON 100uF/16v is the right size. May not even need replacing since it is "long life" but for the dollar or so, may as well. 32X Cap list (VA0 Mega Drive 32X, Genesis 32X capacitors of course are the same) CE3 16v 10uF CE4 16v 10uF CE5 16v 10uF CE6 10v 47uF CE7 10v 47uF CE8 10v 47uF CE9 10v 47uF CE10 10v 47uF CE11 50v 1uF CE12 16v 220uF CE13 50v 1uF CE14 10v 100uF CE15 10v 47uF CE16 16v 220uF CE17 10v 470uF CE18 10v 100uF Sanyo OsCon Solid Cap (16v 100uf same physical size 8mm x 11mm) CE19 10v 100uF CE20 10v 100uF Wouldn't it be fun (lol!) to have a complete list for ALL the retro consoles? I am going through a re-cap phase and would like to re-cap everything up to and including my PS1.....One day.
I've started making spreadsheets... Mega PCs, Aiwa Mega-CDs - all the weird ones...! Keep it up though Just be careful that you don't go cap-crazy. It's a troubled road... Edit: Actually speaking of low-ESR, a P4 LGA775 board I have had a blown cap just like that... Fun! Still waiting on mine to arrive!
You mean 100uf/10v? I dont really know why there was much confusion in the first place, the picture in the first post is pretty clear IMO (you even state it all yourself, then go on to question yourself). Basically, you were right the first time lol
My main reason for questioning it was because it was physically bigger than the other 100uF cap (the other one is about 5mm x 11mm vs 8mm x 11mm) the reason why is now clear. With the cap in place, I couldn't make out the markings clearly on the other side (OsCon) as it was playing hide-and-go-seek behind the other caps around it. Removing it was a case of "Ahhhhh I see!" I pointed out 100uF 16v to go in it's place as it is found on ebay easy enough. The 10v seems to have shrunk, but gotten bigger in diameter which is an issue due to that cap being on the outer edge and having the RF shield in the way. There are seller's on ebay selling what seem to be copies that are the right size, but not sure if one could have confidence with that. Maybe I should have said as such above, sorry for confusion.
I always use caps that are rated a step higher in voltage then stock overall in all the years of electrical repair i have done. They last alot longer.
+1 for derating capacitors. I've only had to do it for tantalum caps so far, just another thing to think about when the time comes... :biggrin-new:
