identificate component
« on: March 09, 2020, 02:22:54 pm »
Hi :) , need help to identificate one component marked as 822K 6011. I need to replace it, it’s blown.

It's a capacitor. The first two digits represent the value in pF, with the last digit, the number of zeros, so that's 82 00pF, or 8.2nF and K means 10% tolerance.

Is it without polarity?

Yes. The low value (under 1µF) and lack of a polarity marking, indicate it's non-polarised.

I think it is a 8.2uH chip inductor from TDK(EPCOS).

Found a lot of similar pictures on Taobao, now there is no doubt that it is the inductor produced by EPCOS.

Thanks Zero999 and gamalot!
Yes, it really looks like it's a inductor  :-+

Thanks. I feel a little bit embarrassed for suggesting it was a capacitor. I've not seen an inductor which loos like that though.

I was going to suggest testing for continuity to confirm it's an inductor, but the part is bad, so it will probably be open circuit. :palm:

Yes I does really look like a capacitor.  :)
