Title: Serindipity Cap question
Post by: mlweidl on October 29, 2010, 05:28:24 PM
So im giving pedal building a whack again and i didnt quiet a bit of research and im gonna order everything today but i just wanna make sure i got all the right caps so here we go

470n= .47MF Panasonic ECQ
100pF= .1MF Topmay
100n= small bear didnt have a .1uf so im going to a local stor to get a ceramic cap
3n3=.0033MF Panasonic ECQ
470n= .47MF Panasonic ECQ
100uF= 100Mf Axial 16v
47u= .47MF dipped tantalum

The only ones i wasnt too sure on was the 47u which is C7

Diods resistors and trasistors i was ok on thanks for your help

100 pF is not .1 MF its 0.0001uF(MF) but just use 100pF http://www.smallbearelec.com/Detail.bok?no=969 (http://www.smallbearelec.com/Detail.bok?no=969)

100n = .1uF and can be found here http://www.smallbearelec.com/Detail.bok?no=890 (http://www.smallbearelec.com/Detail.bok?no=890)

47u is a electrolytic (radial) its just missing the F

also don't get axial caps for the 100uF

axial looks like this, you want radial electrolytic caps

this is a serendipity board populated. I also used the panasonic caps for c1 and c5 470nF
I would recommend a topmay box cap for the 3n3 and the 100nF or confirm that the ecq you are ordering has 5mm pitch width for the lead spacing. I guess there is a little bit of room to the left of c3 on the board so you could fit a 7mm if you bend the leads in.
I used a hi-temp xicon (orange) cap for the 100uF but any radial cap will do.
I used a mini xicon cap for the 47uF electrolytic but you could use a regular size one as well.
