Hi guys, just wondering what is this capacitor value. Picture is not very good so here's what it says textually: ( it's the one on the right side)
3m
100
AKA
3m
100

Re: Capacitor value
Can you measure the voltage in-circuit? -
Re: Capacitor value
No i Can't but what i can say is that I have an other board like this and on the same position there's different cap's with value:
100
46
this would be 46uf, 100v ???Comment

Re: Capacitor value
For that form factor of the SMD cap, the 100 = 10uF. 101 = 100uF, that is how most companies use for marking. The 3m (not the 3M US company) is more likely the company name/symbol.
Do you have capacitance meter? ESR meter? Is the cap bad?Last edited by budm; 11-08-2015, 12:34 PM.Never stop learning

Re: Capacitor value
Can you determine whether the capacitor bypasses a particular supply rail? You could test for continuity with known interface pins or IC power pins.Comment

Re: Capacitor value
Hi guys, sorry for the delay. I do have a MSR meter but could this help me figure the value of the capacitor? My MSR meter is pretty cheap and only gives me the inside resistor value... Here a picture of the other board, so C8 and C12 are the ones i need to replace on the other board. Would those be 10uf 46v ?
The cap i need to replace has been accidentally damagedAttached FilesComment

Re: Capacitor value
IC502 is FAN1587 Linear regulator IC
Those to caps are filter cap, one for the adj pin and one for the input pin.
It recommend using 100uF electrolytics cap, so 16V~25V cap should be fine (you can measure the Voltage on the input pin, output pin.
Learn more by looking at the spec sheet attached.
You can tell what the output Voltage should be by looking at the values of resistor network for setting the output Voltage.
I would leave the cap at the adj pin alone but I would change the input and the output caps.Last edited by budm; 11-14-2015, 05:09 PM.Never stop learning

Re: Capacitor value
Thank you very much budm, why manufacturer are making it that hard to read their cap value??
This is a Toshiba barcode printer circuit board.
Anyway, thank you every one for your replies.Comment

Hi people, I hope this is the correct spot to post this, I'm new to the forum.
I have an RTX 3080 Founders Edition which has a burnt up capacitor (it was in parallel with another capacitor which appears damaged too), so I am hoping to be able to identify the capacitor values and order replacements.
I hope these photos make it clear which component I am referring to:
(yes, the soldering is a bit botched from removing the blown one, I know)
I have found the board schematic (attached), but there does not seem to be a boardview available. I have never... -
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... -
a few days ago I finally purchased mser-100 v2 and I tested its abillity of measuring ESR value.
I found that It shows pretty accurate ESR value for electrolytic capacitor,But When I measure polymer capacitor of dreamcast game console,I found that one third of polymer capacitor's ESR value is more than twice the value of ESR meter table.(for example, I measured one polymer capacitor of 6.3v 100uf, It showed ESR value of 7.68)
Although my dreamcast now turns 20 years old but it still works. I occasionally have played game with it.
Is this ESR value of polymer capacitor correct?...
