My OOMA died. There's no power-up so I'm thinking its the capacitor. I opened the device and and see the cap is a surface mount type. I want to try to replace it with a radial type one (after watching a guy on Youtube do it) but don't know which one to buy. The markings on the surface mount capacitor is "100 CFK B03". Can anyone tell me what this translates to?

Re: OOMA Telo fix
So I guess its a Chinese capacitor and I can't find any info on it. Assuming it's 100UF, and the electrical adaptor for the device is 5V, is it safe to say that a replacement 100UF 10V capacitor would work? -

Sometimes you need to break shit to fix it.... Thats why my lawnmower doesn't have a deadman switch or engine brake anymore

Re: OOMA Telo fix
I found this Panasonic Capacitor pdf, It liooks like the C is the voltage (16volt) FK is the series (page 42)Last edited by R_J; 02-19-2017, 07:03 PM.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... -
TE Circuit Protection offers the widest selection of surface-mount fuses available for addressing a broad range of overcurrent protection applications. Helping to prevent costly damage and promote a safe environment for electronic and electrical equipment, our single-use chip fuses provide performance stability to support applications with current ratings from .5A up to 20A.
TE Circuit Protection also offers the telecom FT600 fuse for telecommunications applications. This telecom fuse helps comply with North American overcurrent protection requirements, including Telcordia, GR-1089,...10-07-2024, 06:07 AM -
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... -
Hi all,
I have a faulty monitor, the surface mount electrolytic capacitor 33uF 100V needs to be replaced, now I can't seem to source them locally
, so my question is can I replace it with a through-hole electrolytic capacitor of the same value? Or has someone got a better suggestion?
Cheerio... -
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,...
