Long time, no post for me.
I was hoping I could lean on you to help me identify a component.
I know that this is 9 pin SIP resistor array, I am guessing it is 1.5kOhms. The markings are so generic though that I cannot glean any further information about it. Google searches have not revealed any useful information.
I am hoping somebody here might be able to tell me a little more about it, is it isolated, bussed, circuit configuration, etc?

Re: Please help identify a capacitor
I appreciate your help.
So, the ".7" after the twenty doesn't mean anything? I wasn't sure if it was a multiplier or some sort of tolerance specification I wasn't aware as this is the first time I have actually seen mica capacitors and it was really throwing me off. -
Please help identify a capacitor
I really hate to post a newbie question, but I need help identifying a capacitor. I have attached a photograph containing two capacitors, I am almost certain they are mica capacitors. I have searched for how to read the codes on the capacitors and I just cannot seem to figure out what they mean. I also tried measuring the capacitance with my multimeter to try to narrow down the possibilities to give me a clue as to how to read the values, unfortunately my meter gives me wildly inconsistent numbers every time I try to test the capacitance, so no help there.
If anybody can tell me... -
Re: Dell studio 1558 CMOS battery connection on motherboard damaged
I had the exact same thing happen to me (on the exact model laptop you have), I went to replace the battery and the holder broke off the board taking the trace with it.
You could probably bodge a small wire in if you wanted to do so.
Here is what I did to repair my board:
I desoldered the existing SMD battery holder.
I bought a new SMD CR2032 battery holder.
I sourced some high purity, very thin copper foil.
I cut out a new trace with an Exacto knife and a...Leave a comment:

Thanks for the input guys, but this project is going to backburnered until after my move is complete. I will update in a couple of weeks.Leave a comment:

Re: Increasing capacitance?
I know that I have 1500uF 16V Panasonic FC's on hand, I don't even have to go looking through my collection to find them. I might have to try putting one in.
And, yes, the 2200uF 16V FC's are 12.5mm, but I know I can make them fit, a little heat shrink goes a long way
As for pictures, I am currently in the middle of moving and my digital camera is buried in one of my boxes, so any pictures will have to wait at least a week and a half.

Re: Increasing capacitance?
It is a Jameco, but there were a couple of Fuhjyyu caps in this supply. No, I don't think the capacitor has failed, this supply isn't that important to me, so I am really just tinkering with it at this point. I believe I have a few 2200uF 16V Panasonic FC's in my collection, do you think I could get away with using one of them?Leave a comment:

Increasing capacitance?
I am recapping a power supply and I've hit a snag, my supply has a 1650uF 16V capacitor. I can't find a suitable capacitor of those exact specs. So, since I know it is a bad idea to decrease capacitance, my question is: how much higher than the original capacitance should I go? Plus, I've noticed that the 12V rail is a bit low, 10.6V, would increasing the capacitance increase the output voltage?
Thanks,

Re: PC Power & Cooling Silencer 400 ATX Question
I know this is a very old thread, but I thought I would let you guys know I made progress on this project today. I am moving in about a week, so I've been trying to finish up a lot of my backburnered projects.
I took a second look at the supply, rechecking my solder work and polarity of capacitors. I managed to find that one of the capacitors, a 3.3uF 50V capacitor had a torn trace leading to the negative side. So, I made a new trace and epoxied it down to the board and resoldered it in place.
I turned...Leave a comment:

Re: MSI P45 Neo (MS-7519) complete (almost) poly recapping
Thanks, I definitely feel more confident about poly-modding now that I've tried it. I will admit this was a pretty expensive experiment, all things considered, especially when I just donated the system, I was just seeing if I could do it.
It's good to know that MSI boards are tolerant to being poly-modded, I know they are not all that popular on this forum, but I've personally always had very good luck with MSI products, perhaps they don't make the best choices when it comes to caps (of course...Leave a comment:

Re: MSI P45 Neo (MS-7519) complete (almost) poly recapping
I'm sorry to hear about your difficulty in obtaining genuine Hakko equipment, I suppose that since I am a spoiled American, I sometimes forget that the rest of the world does not have the same level of access to things as we do. Despite its appearances (the blue and yellow coloring almost makes it appear toy like), my station just exudes high quality, it is solid and robust, and is an absolute joy to use compared to my Radio Shack iron. I can't even begin to fathom why people out there produce counterfeit...Leave a comment:

Re: MSI P45 Neo (MS-7519) complete (almost) poly recapping
My main soldering iron is a Hakko FX-888D, it is the new digital version of the venerable Hakko FX-888, it is digitally controlled, and for less than $100 USD it is an excellent iron for the price. I know that it might seem a tad expensive for somebody that is starting out, but my first two irons were from Radio Shack, the first was just one of the ones you plug directly into the wall, it was useless, I upgraded to their iron that has a high/low setting, it was better but still not great, in retrospect, I...Leave a comment:

Re: My first re-capping mistake and advice
Just to bring a little closure to this thread, I got the replacement capacitors in today, soldered them in place (I did replace both the vented one and the non-vented one). The power supply now works perfectly.
Thanks for the advice,

MSI P45 Neo (MS-7519) complete (almost) poly recapping
Hi Guys,
I actually have something relevant to contribute today! I bought this MSI P45 Neo (MS-7519) motherboard months ago on ebay. I bought it for a couple of dollars because the seller said it didn't work at all, from the pictures, the LGA 775 socket didn't look trashed, so I rolled the dice and bought it. When I got the board, since I didn't have any CPUs or RAM that were compatible, I was unable to test it, but I have no doubt that the board was non-functional based on the fact that every single one of those awful OST capacitors that cover the board were either bulging at the... -
Re: My first re-capping mistake and advice
Is it feasible that approximately 90 seconds ... two minutes tops in my circumstance, would have caused the kind of damage you are talking about?
Both Mouser and Digi-Key sell EEU-FC1C332's for close to a $1.50 apiece, if you have a source of them for less than a 50ยข apiece, I want to give them my business.
Regardless, I was thinking about replacing them both anyway, taking the thing apart is a real pain, and I don't ever want to have to do it again....Leave a comment:

Thanks for the advice, I will probably order two new ones, just in case. But I will only replace the one.Leave a comment:

My first re-capping mistake and advice
So I recently performed a recapping on an Antec Smart Power PSU. I chose to replace all electrolytic capacitors, I used mostly Panasonic FC series and a couple of Nichicon HE's. I finally reassembled it into the case and fired it up, the 12V rail was fluctuating pretty extensively, but the 5V rail was rock steady. I thought that I just needed to apply a load and maybe it would even out. But as I was contemplating my next step, steam started pouring out of one of the two Panasonic FC 3300μF 16V capacitors, it almost looked like the steam coming out of a tea kettle, and surprisingly it did... -
Re: HELP! - my girl is kicking the lead out of the house!
I think that the main reason that people here are advocating to not move to lead free solder, is that there really is no compelling evidence to throw out the baby with the bathwater. This fear of lead free solder is much akin to most of the green movement, it represents an ignorance by those who seek to do good, but don't truly understand the complexities involved, just consider the recycling movement, it costs more, doesn't help anything, and, contrary to popular belief, is worse for the environment, like recycled paper,...Leave a comment:

Re: Microsoft to re-design windows 8 interface.
Is it just me, or does it seem like consumer grade MS operating systems seem to skip generations where quality is concerned? MSDOS 6.2/Windows 3.1 was a really good OS (I can't ever remember it crashing even once), Windows 95 was pretty mediocre, Windows 98 was good once the SE version rolled out, Windows Millenium Edition was attrocious, Windows XP was terrific and has remained popular even to this day (I still use a lot of PCs with XP), Windows Vista was absolute garbage, Windows 7 is quite good (it's one of only two MS OSes that...Leave a comment:
