    0.047uF/47nF/473J -> check local shops for that one

    more or less everything will agree

    cheers

  • Just for my understanding, are these the capacitors in the BOM that the parts list is talking about? What does "Package/Pitch" stand for from the parts list?

    ---Capacitors from the Mouser BOM---
    * Is this for C51, C52, C54, C161?

    4700pF = 4.7nF = 0.0047uF = 472 (J is for tolerance J = 5%)
    0.047uF = 47nF = 47000pF = 473
    that are two different caps

    OK? ;-)

    Thanks lukep. What does 472 and 473 stand for?

    Were the capacitors I posted above the correct ones from the BOM?

    Apologies for these basic questions, I'm really new to this

    Thanks!

  • For ceramic/film capacitors, the first 2 numbers gives the value and the third is the multiplier, for exemple:

    47pF marked 47
    470pF marked 471
    4700pF marked 472
    47000pF = 47nF marked 473
    470nF marked 474

    Same for some potentiometers:

    100 ohm = 101
    1K = 102
    10K = 103
    100K = 104
    and so on

    The pitch is the spacing between the two legs of the capacitor (also called lead spacing sometimes).

    The capacitors you mentioned seems to be the right ones.

    Thanks a lot for this info! That was very helpful for me :)

    I did a little more reading and found this overview/guide on capacitance values too. Here's a link for reference, hopefully it helps out others that are new to this as well
