SMT Electrolytic Capacitor with no Voltage Rating

Hello - this is part of a LED headlight / turn signal controller. It seems that capacitor failure is common and identifying a source for them would help a lot of car guys. The circled one is most common and I have a board that has one connector broken off the board. Is a replacement available from Digikey?

Hello @veijones

This is part of the Panasonic FK Series of Caps. Part markings 33 indicates a 33uF and the 2A is calling out 100V. Looks like part number PCE3846CT-ND

Thank you very much - I’ll pass this information on to a young man who is an up & coming board-level whiz. However, I started to place an order for this item and it reports as back ordered. Is there any other compatible item that is in stock?

@veijones

Take a look at P124612CT-ND we have these in stock right now and looks like the specs match up.

Hi, I am hoping to identify a capacitor which has been giving me trouble for quite some time. It is from an LG Flatron monitor which, after many years of faithful service, began to make a loud whining noise as it turned on, eventually morphing into flashing off and on several times until it stabilized, and eventually into continually flashing and never fully turning on. I suspect, from the loud whining noise and the flashing, that it’s a capacitor, and from what I can see of the circuit board, it only has 2, one being tiny and the other being quite large. I suspect the large one has seen its last day, but it doesn’t look completely burst, and for the life of me I can’t figure out how to read the code on it to identify what kind of capacitor I’ll need in order to replace it. I assume “100v” means 100 volts, but from what I’ve seen of other capacitors, even that may not be an accurate assumption. I’ve been stuck using my old 720p monitor for a couple of years now, and I would love to get my primary back in service.

Thanks so much,
Robbie

Hello Robbie. Thank you very much for contacting us, and I hope what I found helps.

I recognized the logo on that capacitor as being for the Samyoung company. I’ve been looking through their catalog for surface mounted capacitors, and I do believe that the marking shown does call out 33µF 100V.

The ones I could find where the top line (the lot code) ends in a J are the BXJ series, rated up to 105°C. In that series, the 33µF 100V is called out as being 10mm diameter, 10mm height, and a 10.3mm*10.3mm surface mount land size. The closest match I could find in our stock to that capacitance, voltage, size, and temperature is the Nichicon UUX2A330MNL1GS, Digi-Key 493-6281-1-ND.

Fantastic! That looks to be the same size! I wasn’t sure with what I had been reading whether the 33 meant 33µF or 3.3µF, since those were both available options and I honestly am not well-versed enough in electronics to know which would be normal for a monitor. I was lost researching it at first, too, because I thought the first symbol was a weirdly misshapen 6. It wasn’t until I started looking at other capacitors online that I realized it’s some kind of company logo instead. xD

Thank you so much for your help, Justin!

Hello @KAWI_SI

This appears to be an obsolete part number ECE-V1EA470UP looks like the manufacturer has offered EEE-FK1E470AP as a replacement.

Can anyone help me out?

Hi anyone czn help me to identify the valor of this cap.
Thanks

Hi Welcome to techforum! the one marked 560 would be a 56uf and 4 should be the voltage. I am unable to verify the size by photos, but you can check link below for part UWX0G560MCL1GB to see if would work after you measure you part. This one is 0.209"" L x 0.209"" W (5.30mm x 5.30mm) in size. The other looks like 680 which would be 68uf ( confirm the 6, as it also might be a 5?, photo is a little distorted on that number.) You can check out 732-8471-1-ND for that one, it is a 6.8v, we do not have anything in a 4V for that one. Again, depending on your dimensions. This one is 0.209"" L x 0.209"" W (5.30mm x 5.30mm)

Hello,

It looks like this is a 47uf 25V capacitor. Here is a link to some possible options: https://www.digikey.com/short/4q773d
