Missing capacitors - Which one to get ?

Hi,

I'm building my Yocto and I'm doing the Middle Tom right now, I was checking the list and getting the right parts from every little plastic bags and when it came to the Polyester capacitor (2A273J), I found only one left, although I needed two. I also quickly checked on the next chapters, and I found I needed at least 4 more to finish the Yocto. So I'm 5 caps short on this value.

I went to my local electronics dealer and all I could find were these, which were labelled as "plastic" on the box (well maybe not exactly polyester), and I only could find 22n instead of 27n. Are these okay ? Might there be a quality difference ? I think with a tolerance of 15% on this cap I think, I can get up to 30% off from the original wanted value, will that change a lot of things ? For example if it's tuning related ?

Thanks,

Léo

Hi,

look if you have 273K caps in your kit.
Those are the ones that I had in mine. Same capacity, just different tolerance.

Well in the little bag with all the caps starting with 27, I have only one 2,7nF (272) cap left, so it's not tolerance related, I just have missing 27nF capacitors and I'm not sure if I should use the 22nF ones.

Well the 22nF you need aswell so it looks like a you had a "monday morning" batch.. Either ask Vincent, or just order them online, probably the easiest..
