SMT cap identification?
« on: January 02, 2016, 02:52:40 AM »
I have a Sega Saturn sitting here that I was going to replace the caps on. I understand this forum isn't really a site for tech info on these consoles but my question relates to the caps and I know people here know more about them then I do.

Anyways, the SMT caps on the mainboard have markings I am unfamiliar with.

Like:

D5h
100
6.3v

or

DSW
1
50v



But there are other caps that have numbers like this on them that I am unsure of what they mean.

47
6S
5A5


Also, does anyone know where I can find a 10 pin mini din that solders into the PCB on a 90 degree angle? I can't find one in my google searches but maybe I have not looked hard enough yet.

To help out here is a pic. It's the one next to the lettering CE35. I guess I just need to make sure that this is a 47uf cap. There are 4 on the board. I can grab whatever voltage caps to replace them that are the same dimension. I will prolly just get the highest voltage in the same physical size range to be safe.

Pardon my ignorance, but does the Saturn suffer from leaky caps?

I've never heard of it being a problem personally.

I haven't either.

lasers going and bad cart slots are the main gripes I've read with the Saturn.

@MNKyDeth. If you're on any forums with a guy named zyrobs, I'd ask him.

My Saturn has sat in a basement for nearly 20yrs. The main thing is I am replacing the pickup lens and I wanted to recap the power supply board on it.

I figured since I am opening it up anyways I might as well just do the whole thing. It's only a couple extra bucks to recap the mainboard on it so....

I am cleaning everything internally and externally on it as it had a bit of a dust/dirt film on it. I am doing the same thing to a PS1 as well. I just want them to be like new and replacing caps is a very simple procedure for me.

100uf @ 6.3 volts and 1uf @ 50 volts.  In the pic it looks like 47uf@6volt. Usually on SMD caps the cap value will be directly above the voltage rating.

Cart slot's a bitch. If you never used it, it rusts and becomes wonky. If you used it, the pins may have gotten bent from the cart being left in and became wonky once the cart's taken out.  Saturn's one of those system where you should get a decent everything-in-1 cart and just leave it alone in the slot.

I just got done decapping the entire Saturn as I have my replacement caps sitting here waiting to go on it.

Almost all of the caps did look good. However, the surface mount caps on the mainboard of the Saturn I found 8 leaky caps and 4 were already corroding the board itself.

If it's not a problem with these consoles right now, I have a feeling it's soon going to be soon. There was no damage to my mainboard PCB yet just the contacts were showing some corrosion on the 4 specific caps. The other ones that were leaking seems they have not been doing it long but there is the obvious fishy smell from them.

So just a heads up to anyone out there that has a Saturn and think it's gonna last another 20yrs. :) Might want to be a little proactive about it.
