Understanding SMD Electrolytic Capacitor Coding
By Jestine Yong on July 15, 2010
If you are repairing Mainboard I’m sure you would have came across SMD electrolytic capacitor that have marking on top of the cap. Some value are quite direct like 47 and 16 means 47 microfarad with 16 volt working voltage. However some SMD e-caps that have alphabet letter and you need to find out what is the meaning of those alphabet letter. Please click on the photo to visit the website and scroll down to check on the answer.

How about the following capacitor on laptop motherboard:
100
EFK.
Q62
Please help

HI Samuel,
It is 100uf but not sure on the voltage. Since laptop uses low dc voltage a 25 volt would be safe.

I've got a SMD Electrolytic Capacitor that says on the top:
2N
470
16A
I am not sure what really they mean. Any ideas???
Thanks!

HI Franklin,
Try check with digital capacitance meter to see if the value is 470uf.The working voltage is 16 VOLT.

330A
UD
any ideas
Thanks

November 14, 2011 at 12:46 pm
HI Adam,
It should be 330UF 10 VOLT CAP. Please refer to this link:

I got one that has me stumped big time.
98 (Looks more like a 0 with a - though it)
100
ELA (LA are still Upper case but are smaller than the E)

hi i am from india and i want to know all code of capacitors
like 2a meand 100v 2g means 400v please i want help any webist or anything

Hi Vishal,
Sorry i do not have such code.

Hey!
I have an aluminum surface mount capacitor marked:
x4507
100
25T
I am assuming that means 100UF and 25V, but I have no clue what the first part means. I also have some where the top section is "33080", "41514", and "V1214". Any help on what these mean would be greatly appreciated.
Thanks!
Jestine Yong
March 28, 2012 at 1:31 am
Hi corey,
Yes the value of 100uf 25 volt is right but I have no info on those front code. I have searched the net but could not find any answer. It could be codes that can be understood by the manufacturers.

i have a capacitor numbering
671
100
25z
what is the meaning....
Jestine Yong
September 9, 2012 at 4:03 am
Hi Hasan,
Most probably 100uf with 25 volt. You can use your digital capacitor tester to confirm the value.
Jestine
Hasan
September 9, 2012 at 10:50 am
Thanks Jestine
the another one is e-cap numbering
645
SVP
1200
4
this is the complicated one.......
please help
Jestine Yong
September 10, 2012 at 8:23 pm
Hi Hasan,
If the e-cap is very small then it could be a 1200uf with 4 volt working voltage. I suggest that you confirm the uf by checking it with a digital capacitor tester.

86
100
16A
What is this ? Thanks !
Jestine Yong
October 10, 2012 at 8:37 pm
Hi Denny,
Most probably a 100uf 16 volt cap
Jestine
Denny Miller
October 10, 2012 at 8:45 pm
Thank You very much. Does the 86 have significance ?
Jestine Yong
October 10, 2012 at 8:49 pm
Hi Denny,
Sometime those code could only be understood by the manufacturer. In order to confirm that the cap is indeed 100UF you can use a digital capacitance to test it.

Could you give me some explanation?

Jestine Yong
January 19, 2013 at 9:09 pm
HI Zoli,
There are too many coding in SMD caps. This is a 1000uf but not sure on the voltage. If the board use only 5 volt you can always put in a 10 volt cap.
Jestine

i can understand 470uf , but not sure the voltage , it is in laptop motherboard
thank
Jestine Yong
January 25, 2013 at 10:21 am
Hi Jim,
If in a laptop you can use 16 to 20 volt e-cap with 470uf. Sometimes it is hard to find the meaning of those coding.

hello
I have a supposed bad laptop motherboard capacitor on the top of which is written:
100
EFK
7G4
Would you like to help me the meaning,please.
Many thanks
Jestine Yong
March 17, 2014 at 9:40 am
Hi Haja,
100 means 100uf and the code you have to refer to the respective website for answer. From experience dc voltage in laptop is not high so a smd 100uf with 35 volt could do the job well.

Hello
I have a bad motherboard cap and can't figure out the reading any help appreciated
98
68
25k
And
I think a 9z 100 16v is definitly a 100uf 16v cap and the first digits 9z are the manufacturers lot or item code.
Thank you
Jestine Yong
May 17, 2014 at 5:51 pm
HI Keven,
The first one is 68uf 25 volt and the second one is 100uf 16 v.

August 16, 2014 at 4:37 pm
Hi Stephen,
It is 470 uF. As for the volt you can use 25 or 35 volt if the circuit board is using max of 20 volt.

Hi Japheth,
Yes you can try that. Make sure it is the electrolytic type with same or higher working voltage

i have find SMD electrolytic capacitor problem in dynisco ATC 770 pressure controller. but not identify the capacitor range.
1) 100 VFC 1F6 or 100 VFC 3FN
2) 47 VFC 1K5 or 47 VFC 3T4
3) Z1 10V UD or 12 10V UD
admin
December 1, 2014 at 9:27 am
Hi Muthazhagan,
Since the cap value is in coding format thus I suggest that you check it using the digital capacitance value. If 100VFC you got 100uf this means the VFC is the microfarad. If you get 1F6 as 1.6 or 16 uf this means the 100VFC is the capacitor working voltage.

05 100 16G , and I dont know with which other cap I can replace them.
Thank you
Jestine Yong
January 24, 2015 at 2:09 pm
Hi Ranko,
The first one you can use 470uf with 25 volt and the second one 100uf with 16 volt.

HI Jose,
33uf,68uf,220 uf,10uf 16volt. As for the voltage, if the circuit board is using only 5 volt to run then use 16 volt in all caps.

Jestine Yong
May 27, 2015 at 7:40 am
Hi Chris,
The first one should be 1000uf (if the board is running on 5 volt or lower then use a 16 volt) and the second is 100uf 16 volt.

Hi David,
Use 470uf and if the line voltage is around 10 to 12 volt you can use a 16 volt cap. If the line is 16 to 20 volt you can use a 25 volt cap.

I suggest that you compare with the similar value cap in the same board using digital capacitance meter. The value most likely is 100uf 35 volt.

Is this a 4.7 micro farad 10v capacitor ?
Jestine Yong
January 14, 2016 at 8:47 pm
HI Narine,
It should be 470uf and probably 25 volt. If you circuit is using 10 to 16 volt then it should be 25 volt.
