Re: Need help to identify capacitor brand
The electrolytic cap is close to the motor H-bridge IC, and likely for local decoupling.
Note that the PCB will accomodate a larger cap there, the footprint is larger. The 10uF is likely not critical at all, for ESR.

Sorry for missing information. It´s a panasonic floppy from 1991.Leave a comment:

Re: Need help to identify capacitor brand
It may be an ordinary surface mount electrolytic cap rather than a polymer. If so, a good quality 105C general purpose part would probably suffice.Leave a comment:

Re: Need help to identify capacitor brand
actually it looks like the ceramic cap infront of the chip has been broken away from the board on one end.Leave a comment:

Re: Need help to identify capacitor brand
It looks like there`s some corrosion as well on the IC above that cap .Leave a comment:

Re: Need help to identify capacitor brand
well it looks like a nippon-chemicon symbol on it.Leave a comment:

Re: Need help to identify capacitor brand
Thank you for the reply.
It´s not a thing how to replace the cap, I have all these nice tools and know how to use them. I am just searching a cap with same spec in terms of esr and ripple. I knew that the one on the picture has 10uf and is 35v rated, but can´t see any other spec.
Don´t want to solder mlcc or tantalum cap.Leave a comment:

Re: Need help to identify capacitor brand
it's 35v rated, but it cant be seeing more than 12.
i personally would use a 25v tantalum cap.
no point trying to fit another smd electrolytic - they are all junk and unless you have hot-tweezers you will probably damage the replacement anyway.Leave a comment:

Need help to identify capacitor brand
Want to repair some broken floppy disk drives. I need help to identify the brand of this capacitor to find a suitable replacement.
Did someone know the brand of the capacitor or a suitable replacement in terms of esr / ripple?Attached Files -

This is a cap on a motherboard from 1994. “Ark” is the only brand I know of that has an A inside a rectangle, but I wanted to run it by you guys and get any thoughts on quality.
Thanks in advance.... -
Hello everyone,
I have an Dell Inspiron 15 3537 laptop mainboard (LA-9982P Rev. 3.0 (A02)) with a blown SMD capacitor as shown in the attached images. However, there is no printed specifications near the capacitor or a codename for the capacitor to identify the specification of the capacitor to replace it. I wonder how to identify the capacitor since the mainboard schematics are also useless as the capacitors are not named on the board. Any help would be highly appreciated.
Thank You. Stay Safe.

I replaced some capacitor which is located on optical pickup pcb which is shown in the table below(PCB #2).Because it have been out of order.
Now,It works very well,But I just have found that all caps (6svpc100my and other part number as well) ,which is shown in the table below, has ultra-high ripple current spec.
It is not able to obtain any capacitor which can be a substitute for this ultra-high ripple current nichicon capacitor.
So I replaced it with samxon and rubycon's general capacitor(GP,YXA series).
I know that these capacitor will not last as long as nichicon capacitor... -
I desoldered samwha NF capacitor(50v 5.6uf) from PCB circuit of 29inch CRT TV which have symptoms of no display after I heard sound of inrush of current to TV whenever I switch on this television.
I measured ESR value of this non-polarized capacitor(samwha NF capacitor 50v 5.6uf) by means of MESR-100 ESR meter and It displayed 0.3 ohm
And When I measured its capacitance with digital multimeter and LCR-T4 Mega328 meter, It displayed 10uf from DMM and 8uf from LCR-T4 meter.
I found catalogue of samwha capacitor(samwha-catalogue_3.pdf file), which is attached to this thread,... -
When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.
Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
Rubycon YK DataSheet (b...
