  • trouble indentifying caps

    hi peeps,finished loading the board with the components done all the relivent tests i can do with a speker,i have no ocilascope,its making all the correct noises,but im not confidant ive put certain caps in the right places because whats in the manual reads different to whats printed on the caps.ive taken a leep of fath and put 1k63 in c10 with 2nk2100 squeezed in c11 next to it. the fact that it was a real squeeze tells me that its not right,have i done the right thing,you help would be greatly appriceated thank you

    Hi slowsweeper;
    I checked my board and the schematic diagram for the following:

    The 1k63 should be in the C18 location.

    C10 should be a 10nk100

    C11 should be a 2n2 = 2 pf ; about 1/3 of the size of C10 and a yellow dew drop shape

      2n2 is not 2 pf it is 2.2 nf just saying.

              Hi!

              10nk100 is 10nF, k=10% tolerance, 100 is voltage
              2n2 is right, it is equal to 2.2nF

                I as well am having the same issue, at C20 - 100pf, is it the tiny ceramic cap labeled 101 in the kit, I was looking for a cap chart or conversion chart and if memory serves me the 101 is the small
                100pf cap in the kit, C8 as well is a 220pf and must be the other ceramic cap labeled 221.

                Can anyone reassure me on this before I stickem...

                Thanks guys

                  Yes 101 is 100pf and 221 is 220pf

                    It is correct.
                    The last number means the number of zero.
                    1 is one zero therefore you must read as 100 and 220.

                    Instead if you have, for example, 103 it is 10'000pF alias 10nF and 224 it is 220'000pF alias 220nF.

                      That's exactly what I was lookin for, I thought there was an alternative I could use but wasn't sure of the ceramics numbering.
                      Thank you very much.
