Capacitor question Subject description: 2u2 NP |
|
|
Here’s my latest stupid question. I assume C10 on Andrew Sharp’s components list is supposed to be “2uf NP” instead of “2u2 NP.” If “2u2 NP” is correct I don’t know what that is. I have 1uf NPs. Is it possible to use those instead? I found on Google that I can use 2 1uf NPs “in series but with like polarities connected together.” What would this look like on the stripboard layout?
I should be finished with it soon (one way or another) so my stupid questions will end.
Thanks,
Kevin |

2u2 is a compact way of saying "2.2 uF". In the original schematic, C10 is .1uF. Either way, it doesn't matter much, it['s just there to stabilize a reference voltage, created by two resistors (R75 & R73). I saw the strip board layout page, and it says all the designators are the same as the original schematic, but I didn't find the component list you spoke of.
So, you can probably use just the one 1uF you have, or use a .1uF if you've got it. I don't think the value is extremely important. |

outside the US, its pretty common write parts values by putting the units where the decimal point goes... so 2n2 is a 2.2n cap; 4u7 is a 4.7uf, etc. decimal points can often get lost. Caps can also be "NP", which means "non-polarized"--electrolitic caps are usually polarized, but you can get some that aren't.
