Help identifying SMD electrolytic capacitors
« on: March 01, 2021, 11:26:01 am »
Hi everyone,
I'm having some troubles identifying this 2 caps:
1184268-01184272-1

In case you can't view the pictures, the caps have the following texts on the top:
CAP1:                            CAP2:
2J                                  E24D
220                                560
AZA                                2,5V

I have used this to links to try to understand the codes:
https://www.electronics-notes.com/articles/electronic_components/capacitors/capacitor-codes-markings.php
https://kaizerpowerelectronics.dk/theory/capacitor-code-table/

My best guess for cap1 is 2J means 630V, 220 is 2.2uF, and AZA is the serie or manufacturer. For cap2 E24 is the serie D means 0.5% tolerance, 560 for 5.6uFand 2,5V is the rated voltage. Can anyone confirm if my guesses are correct? I've checked some datasheet for capacitors from some manufacturers (Nichicon, Vishay, Panasonic) and none of them used the codes mine had.

0.5% tolerance
I dont think so. They dont really make these with less than 10% accuracy.

Cap1 might be 220uF judging by its size. Or maybe 22.
Cap2 560uF or 56.
Manufacturers break the rules all the time unfortunately.

Thaks for replying, I guess my best option is trying to find the schematic of the device... I'd hope that caps had a more standardized sistem for identification.

You can  probably measure them in circuit. They dont seem to be broken.
Or desolder and measure if in circuit fails.

It won't be a 630V rated capacitor as electrolytics are rarely available in voltages exceeding 500V, especially for SMD types. The 2J voltage rating code would only apply for film and ceramic caps.

Electrolytics almost never come in tolerances better than 10% so I don't think you have a high precision 0.5% capacitor either.

The first cap looks like a RubyCon:
2J = lot number
220 = 220uF
AZA = A is code for 10V, ZA is the series of cap.

Not sure about the 2nd one except to guess at 560uf @2.5V

It's also polymer capacitor with 99% probability.

It's not Rubycon ZA series since those are through hole parts. It's Nippon (United) chemi-con MZA https://eu.mouser.com/datasheet/2/420/129258960852d6c78f3e2e1-1398177.pdf

Thanks a lot for the help, I'm going to measure the dimensions to get the exact models. It's the first time that I had to search for a cap looking the encapsulation, it seemed ridiculously complicated. Is there any trick to identify the manufacturer and the other parameters just with the top printed codes?

Colors, maybe. (Knowing if a company usually puts their logo on their polymer caps or not can be helpful.)

Black:
Some Nichicon
Some Panasonic
Probably a million normal SMD electrolytics that look like polymers (are we sure the above is not just an "wet" electrolytic?)

Teal-blue:
Nippon-Chemicon (usually has the shield logo, unless cap too small)
Lelon

Red:
FPCAP/Nichicon (usually says FP on it)
APAQ (usually has "C" with dot logo)

Magenta red:
X-CON (typeface uses rather thin-lined lettering)

Purple:
Panasonic
Unicon

Dark blue:
KEMET (usually has big "K" on it)
CapXon (usually has "CapXon written on it)


For your case, my guess is that the teal-blue one is Nippon Chemicon PXE. They usually start with slightly larger letter to denote series. "E" in this case for PXE

The blue one is almost certainly a polymer dielectric 560uF 2.5v , I have some almost identical ones in a PV booster I built.
(I've seen polymer with red labelling too)

I'd be agreeing with the "4thdoctowhofan" as the other being 220uF 10v, it's about the right size.

It's always difficult with these as "560" could be 560uF or 56uF , whereas "561" is always 560uF.

Ordinary electro's wouldn't bother with 560uF , they would numerically be 470uF or 680uF, so they have basically jammed as much capacitor as they could into the can, and at 2.5v that's a lot with polymer. So you could get 560uF/2.5v in the same volume as a 47uF/10v normal electrolytic.
