Thanks for the help. 😊

Hi. I want to replace four capacitors in my washing machine control board. Two are electrolytic's and I don't need help with those. The other two are blue and rectangle shaped.
Can you tell me what type of capacitors they are?
I can read the Farad and voltage values but want to check exact type of cap.
The first one has the symbol P3 on it. I thought it was a safety capacitor but this has confused me. It's next to the choke coil.
The 2nd one has P1 on it. I thought it was a safety capacitor too but again, it confused me.

Context.
My washing machine turns and washes but does not spin fast. I decided to change any caps since it happened during hot weather. I have ordered the electrolytics but want help to make sure I don't order the wrong ones.

They're just normal metallized film capacitors (0.22uF and 47 nF), not X or Y class caps. AFAIK, you should be able to replace them with other normal film caps.

With a bit more digging, I found a piece that is a bit larger but should still work out just fine.

Thank you again for your support in decrypting the stamping on the component.

I could be wrong, but it seems to be Metalized Polypropylene, you could check the value of one of the other caps marked the same for the capacity.
U12 = 0.12µf, 120nF
J = 5%
900 = 900VDC
C6 = Date code y/m ?
ultra-small, metallized polypropylene (MKP) film capacitors

Thanks a lot!
That's super helpful!

U12 is a short code, see page 5 the Codes for rated capacitance table it has two examples µ1 & µ15

Nice! Seems to be the manufacturing date: C = 2012, 6 = June

Went down the rabbit hole to find this component...
Browsed all the links in the sticky post: where can I buy replacement capacitors

and can't seem to find exactly the same piece...

Dimensions from the broken component:
W x H x L
7.5 x 16 x 27
Lead space: 22.5mm


10% tolerance instead of 5%; 800V DC instead of 900 https://www.conrad.com/en/p/icel-mab...0-3437677.html
too wide, too high, 305 VAC - https://www.mouser.lu/ProductDetail/...6DVvGvcQ%3D%3D
0.12uf, 900V but way too big - https://www.digikey.com/en/products/filter/film-capacitors/62?s=N4IgjCBcoMxaBjKAzAhgGwM4FMA0IB7KAbRACYBWABjgF18AHAFyhAGUmAnASwDsBzEAF98YMgE4y8EEkhoseQiXLjxMABxT6IZqw48Bw-GSoAWcdNnyc%2BIpFJUAdGIAEAVoBiIUSZcMv2rqQIACqvNxMAPLIALLYqJgArpzYwiLkygC2ANYMLgioDKgIEQScILRCQA

The closest I found is the TDK B3265* Series - MKP General Purpose, but they don't have one with 0.12uF
https://www.digikey.pt/en/products/f...E8GbFYSzCQhISA


Based on the TDK catalogue: https://www.tdk-electronics.tdk.com/...B32651_658.pdf

The only component they have that has 120nF, over 900VDC, but the size is to big (pink rectangle)
The piece I have, has similar dimensions as the 47nF rated component (green rectangle)




I'm I just terrible at searching? or am I missing something?

It`s a date code , it`s on page 6 in the pdf

I guess I should have looked closer at that pdf, I was looking at other pdf's trying to find the exact value (.12µf) and voltage
what threw me was In some newer pdf's C=year 2032

[SMDFlea]

Even the manufacturer documentation (https://www.tdk-electronics.tdk.com/...codesystem.pdf) mentions it should clearly state the capacitance.

U12 is a short code, see page 5 the Codes for rated capacitance table it has two examples µ1 & µ15

C6 = ?

Trying to fix an induction hob with 3 out of 4 working sections.

After narrowing down where the issue could come from, I discovered a cracked capacitor


Can't seem to pinpoint the exact capacitance based on the stamped data on the component

The producer used to be called "EPCOS" now it's "TDK"
Piece was manufactured in June 2012



Even the manufacturer documentation (https://www.tdk-electronics.tdk.com/...codesystem.pdf) mentions it should clearly state the capacitance.

Any hints would be welcome.

Hi all, trying to find a suitable through-hole induction hob resonance capacitor that fits the following minimum specs: 0.25µF ± 5% 2000V DC, 50mm Lead Spacing.
Cap can have 1,2 or 3 leads on each side (from factory) - this isn’t very important to us.
Pictured below is 2 of the previous resonance cap revisions (black & white), along with the actual upgraded cap revision (blue).

Black:
BYCAP INC.
6A801-254C
25MFD 800V AC
0837

White:
ic
KPF
0.25µF/800Vrms
K/F3

Blue:
MKPH-RM
0.25µF ± 5% 2000V DC
C254200021101QG
524040779
cg-elec / cgegd

(Apologies if any markings have been transcribed incorrectly, only have a failing black revision to hand with the intention of replacing & upgrading it 😅)
Any suggestions on where we could source good quality, reliable caps meeting these specs (to the UK) - or any other info or ideas whatsoever - would be incredibly helpful.

I'm trying to repair a car ECU that shows a fluctuating system voltage (between 6V and 13V in diagnostics) even though the battery voltage is stable. I suspect a faulty capacitor on the main power supply line.

The capacitors in question are a small, yellow, ceramic capacitor located right next to the main power input pin (pin 12) and ignition (pin 13) of the main controller chip. There are no visible markings or codes on it.

I've attached a close-up photo of the capacitors (pin 12 is constant + and pin 13 is ignition + ) and an overview of the board. I've checked the resistance with a multimeter and pin 12 capacitor goes for 0.8MΩ and pin 13 capacitor goes with 2.8kΩ. The ecu was under water so from my little understanding I suspect this could be the problem for the fluctuating system voltage

Could anyone help me identify its likely value? Any help would be greatly appreciated!

[Slydder]

I have a THT MLCC that i am unsure of. could someone help ID this cap please?

thx

[Trond]

I'm recapping my IBM PS/2 P70 PSU and I've found information about most of the caps. However, there are 3 caps that are not found in any datasheet or in the web archive. They are labeled GM & GX.
Someone told me that these are special purpose caps made for PSUs. I'm looking for Information about the Impetance and Ripple Current on these.

RefDes	Capacitance	Voltage	Mount	Diameter/Size	Height	Lead Spacing	Temp	Type	Brand	Series
C009	2.2 µF	400V	Through hole (radial)	10mm	15mm	5mm	105C	Electrolytic	Panasonic	GX
C105	33 µF	250V	Through hole (radial)	16mm	25mm	7.5mm	105C	Electrolytic	Panasonic	GM
C137	10 µF	250V	Through hole (radial)	12mm	20.5mm	5mm	105C	Electrolytic	Panasonic	GM

can anybody identify this 10U_0603_25V6M

10U_0603_25V6M
i need to know what to replace this with i assume it is 10uf and 0603 size, 25volt, but what does the 6m mean, is it 20% 10%
many thanks

[momaka]

So the markings 10V, 470 uF are all I need to worry about? All the other characters on there don't mean anything?

The "HC" marks indicate that these are Nichicon HC series - a low impedance type of capacitor. So you need to get the same type - i.e. match the impedance/ESR and ripple current to generally within +/-30%. The brands and series I listed in my previous post should all be close enough. So just look for, for example, Rubycon ZLH or ZLQ on Digikey, and you should be able to find good-matching replacements.

[scottl31]

The cap that scottl31 posted above is Nichicon HC series, as lti correctly identified.
EB series from Panasonic is not quite adequate in that case, if ESR and ripple current capability are to be observed.

Relatively close replacements would be United Chemicon KZE and KZH or Rubycon ZLH or ZLQ. All of these are readily available on both Mouser and Dikigey ATM. Just match the capacitance and the voltage (10V, 470 uF), along with the diameter. Height-wise, UCC KZH and Rubycon ZLH and ZLQ will likely both be shorter, since they are newer miniaturized series.

*edit*
Forgot to add... Nichicon HW and HV series would also be close enough (if not better), along with Panasonic FR and FS. These are also readily available on Digikey and Mouser.

Happy hunting!

Tranks!

[semiRocket]

Hi, first time I see I cap like this, I suspect it is anyway as it is marked as C124 on the PCB. The markings means 0.1uF, 400V?

Well the in circuit ESR shows around 88ohms, I suspect something is not right...
