Alex Posted August 13, 2017 Report Share Posted August 13, 2017 Hello I am going to be reworking the logic board on an SE/30 and am looking for a list of capacitors for the board. The board I have has already gone through a repair by an unknown third party and I intend to remove all the caps he put in place. I would like to install the original electrolytic capacitors and other caps that the board hosted. I don't want to go with tantalum capacitors because of their very disruptive end of life characteristics, namely they can blow up. I would appreciate if someone in the know could provide me a list of caps and their respective locations. Kindest regards —Alex Quote Link to post Share on other sites
IlikeTech Posted August 13, 2017 Report Share Posted August 13, 2017 Modern tantalum capacitors don't blow up. They are a new chemical formula and they no longer do that. Quote Link to post Share on other sites

ben68 Posted August 13, 2017 Report Share Posted August 13, 2017 Isn't someone here selling a kit with all the necessary capacitors for ten bucks? Quote Link to post Share on other sites
reallyrandy Posted August 13, 2017 Report Share Posted August 13, 2017 Someone used to sell kits but no longer. I would buy one too. I need to recap 2 IIcis, a IIsi, an SE/30 and a Plus. I also need to fix a power board on a Jasmine 20MB Direct Drive. Quote Link to post Share on other sites

Alex Posted August 13, 2017 Author Report Share Posted August 13, 2017 Here's a list: http://www.maccaps.com/MacCaps/Capacitor_Reference/Entries/1989/1/19_Macintosh_SE_30.html Are these correct? Please help me a little further. I found the following on mouser.com. Could I please ask you if the choices made via the links pasted are indeed the correct items? What about brands? Which are the best? There is Nichicon, Vishay, Lelon, Cornell, any advice on brand reputation? 10 - 47µf - 16V - SMT http://pl.mouser.com/ProductDetail/United-Chemi-Con-UCC/HHXC160ARA470ME61G/?qs=u4fy%2fsgLU9PB4oWMgjYECw%3d%3d 1 - 220µf - 16V - Axial (mouser mentions ripple currents of 210, 260 and 298 mA) - which is recommended? http://pl.mouser.com/ProductDetail/Vishay/MAL213835221E3/?qs=sGAEpiMZZMtZ1n0r9vR22V3UFFJUd5NrFZ2eOPpb6YM%3d 1 - 470µf - 16V - Axial http://pl.mouser.com/ProductDetail/Vishay-BC-Components/MAL213835471E3/?qs=sGAEpiMZZMtZ1n0r9vR22V3UFFJUd5NrcJiUFeOA0js%3d 1 - 1µf - 50V - SMT (I don't know which to choose) http://pl.mouser.com/Passive-Components/Capacitors/_/N-5g7r?P=1z0z7ymZ1z0wrj5Z1yx4avv&Keyword=SMT&FS=True Quote Link to post Share on other sites
Alex Posted August 13, 2017 Author Report Share Posted August 13, 2017 Oh I found another link:http://home.earthlink.net/~gamba2/se30repair.html Quote Link to post Share on other sites
ben68 Posted August 13, 2017 Report Share Posted August 13, 2017 My understanding is that tantalum is a better choice. They last longer than you'll need them to, and they are about as easy to install. Someone correct me if I'm wrong here - this is just what I've read. http://www.mouser.com/ProductDetail/AVX/TCJY476M020R0070/?qs=sGAEpiMZZMtZ1n0r9vR22fnRm5uGzJq9RBUATwqbwck%3d Quote Link to post Share on other sites
aplmak Posted August 14, 2017 Report Share Posted August 14, 2017 I only do tantalum replacement when possible.. and I stay away from SMD cans... Quote Link to post Share on other sites
ben68 Posted August 14, 2017 Report Share Posted August 14, 2017 I, too, would like a definitive link for the caps to use, since I'm a novice soldering iron slinger. There are so many capacitors to choose from, even among similar ones. I also buy from arrow.com, so the tantalums that I referred to above are these at Arrow. Quote Link to post Share on other sites
trag Posted August 14, 2017 Report Share Posted August 14, 2017 Isn't someone here selling a kit with all the necessary capacitors for ten bucks? I still do that. I don't know why your respondent claims I don't. Please see the stickied thread in Trading Post. Quote Link to post Share on other sites
ben68 Posted August 14, 2017 Report Share Posted August 14, 2017 Thanks, trag! When I'm ready to do it, I'll buy from you. Does your kit include tantalums? Quote Link to post Share on other sites
reallyrandy Posted August 14, 2017 Report Share Posted August 14, 2017 I still do that. I don't know why your respondent claims I don't. Please see the stickied thread in Trading Post. Sorry, I was referring to this post https://68kmla.org/forums/index.php?/topic/18754-fs-compact-mac-analog-re-cap-kit-15/ I wasn't aware there was another source. I would also just rather buy kits so I didn't have to figure out what I need. Apologies. Quote Link to post Share on other sites
anthon Posted August 14, 2017 Report Share Posted August 14, 2017 I maintain a list of replacement capacitors at https://www.hobbesnet.org/wiki/macintosh:logic-board-capacitors. I have links to specific part numbers I use. I only have part numbers for aluminum electrolytic and aluminum polymer. These are more difficult to solder than tantalum (mainly due to the very small leads). I haven't been convinced that tantalum are better for this purpose. Ease of soldering might ultimately be a big enough factor to tip the scales in my mind. For now I'm sticking with polymer though. Some day I will figure out the best sizes for tantalum replacement parts for comprehensiveness. Quote Link to post Share on other sites
powermax Posted August 14, 2017 Report Share Posted August 14, 2017 IIRC, tantalum caps need to be properly derated, i.e. a 47µf, 16V need to be replaced with a 47µf, 35V tantalum cap. For further details, see this thread. Quote Link to post Share on other sites
Alex Posted August 15, 2017 Author Report Share Posted August 15, 2017 (edited) I hope this helps for those interested in tantalum replacements: …and after googling around, I found this https://68kmla.org/forums/index.php?/topic/15517-fs-tantalum-rework-capacitors-for-those-old-boards-10set/ Edited August 15, 2017 by Alex Quote Link to post Share on other sites

trag Posted August 16, 2017 Report Share Posted August 16, 2017 Thanks, trag! When I'm ready to do it, I'll buy from you. Does your kit include tantalums? Yes, I only use tantalums, except for the Axials, of course. But all the Surface Mount Electrolytic cans are replaced with tantalums. Quote Link to post Share on other sites
trag Posted August 16, 2017 Report Share Posted August 16, 2017 Sorry, I was referring to this post https://68kmla.org/forums/index.php?/topic/18754-fs-compact-mac-analog-re-cap-kit-15/ I wasn't aware there was another source. I would also just rather buy kits so I didn't have to figure out what I need. Apologies. I see the source of confusion. The topic at the beginning of this thread is Logic Board caps. I provide tantalum and axial replacements for most of the logic board caps that Apple used on the pre - 2000 Macs. The link you were looking at was for sets of Analog Board caps, which is also a very useful service and I wish CC333 was still providing them. But different from what I provide. I do not sell analog board kits, although I have a stock of the MR824 rectifiers used on some Analog Boards. Happened across a good lot on Ebay and it's more than I'm ever going to be able to use. It's good that more folks have learned how to order their own from Mouser and Digi-Key and such. When I started providing them, most folks found that too complex, and Digi-Key had a $25 minimum order. That was the main reason I started providing them. So that folks who might otherwise find getting the caps too daunting, would be able to get the caps and fix their Macs. Quote Link to post Share on other sites
Alex Posted August 17, 2017 Author Report Share Posted August 17, 2017 Yes, I only use tantalums, except for the Axials, of course. But all the Surface Mount Electrolytic cans are replaced with tantalums. From what I understand, tantalums can exhibit rather violent deaths, ie explode suddenly and uncontrollably. What are your thoughts? Quote Link to post Share on other sites
trag Posted August 17, 2017 Report Share Posted August 17, 2017 My thought is that I have yet to see that ever happen, except when someone installs one with the polarity reversed. Some models of Mac Logic boards were built with tantalums from the factory, and I've never seen a report of a single one of those having failed from capacitor damage.

radiorich Posted May 16, 2020 Report Share Posted May 16, 2020 Hello everyone, I have a sick Se/30 that I need to replace The capacitors and was wondering if I should go with Tantalums instead the SMD style I do see that list of capacitors anyway Trag I am putting mouser order in so I wanted to get these caps on order is there a list of the analog board and powersupply caps or maybe I will take the boards out I also ordering parts for my Atari 2600 Sincerely Rich Quote Link to post Share on other sites
