component Cap identify

[alkuentrus]

Hello,

I have a doubt about these two caps and I need your help...


47n = ? Capmeter measures 47nanoF

v22= ? Capmeter measures 221nF ...

I dont think its right.... At least the 2nd one...

Regards, thanks in advance...

Re: component Cap identify

u22 is probably 0.22uf
aka 220nf

Re: component Cap identify

1K25 means 1250 V ?

Re: component Cap identify

probably not,
i suspect the letter J relates to the voltage.

Nothing printed on the side?
It looks like EPCOS/TDK capacitor.
Pictures of the whole board top and bottom sides?

Re: component Cap identify

J is the capacitance
K is the voltage

Nothing printed on side... Never seen any like these...
I'll take some fotos of the board, tomorrow at work.
And, yes I've followed the link you gave, and the symbol matches the one printed on the capacitor. I ll go browse deeper Thks

Re: component Cap identify

I recognize the logo as Epcos/TDK.
They all start with B32xxx part number for their film caps. Newer parts are laser marked instead of this mess.
I believe it is a 0.22uF 1,250VDC polypropylene film cap. These caps rarely fail, they are self-healing and pretty tough.

u22 = 0.22uF or 220nF
P654 = B32654 series
1k25 = 1,250VDC
J=+/5% tolerance

Part number might be: B32654A7224

Check the dimensions/size, but it's high-voltage low leakage, high frequency cap for your analyzer.
