Can anyone tell me what values these caps are?

I am always confused on how to read and decipher cap values.I have no problem with pfs and electros as they are easier to read I am building an easyvibe and it calls for the following:

0.001
0.015
0.22
0.0047
0.1

My order from Smallbear came with:

f.01k
F102KK
224k
.1K
F223K
F472KP

There is obviously an extra cap here. Can anyone help me with this? Is there a chart or guide on how to read these? I did not found any on the FAQ
Thanks in advance!

google delivered this with the string "reading capacitor values".

Thanks for the info i have seen those before but i am still confused about changing the outcome of the digits to the decimal value

sir_modulus

use the numbers to figure out the caps. Most of them are really close (they gave you an extra 0.01 instead of a 0.015. The extra cap is the one labelled 224K.

Here's a good link:

Hi

                             

0.001 =F102KK
0.015
0.22=224k
0.0047=F472KP
0.1=.1K

                             
                   
0,01= f.01k
0,022= F223K

You were obviously given a substitue from the nearest value below and above in E6 series
Depending on the circuit, it may not matter all that much. Check location of component for details.

Thanks BJF figured most of them out with the charts that they gave me.I am building an easyvibe . Would it be better to substitute  a slightly lower value or higher one?

Hi,

All good then. I happen to collect fine capacitors so some things just sit at the back of the head.

Hm, well it depends on the location in the circuit what makes best substitution- sometimes change would be unnoticable and most likely either value would work just fine with approximately the same results.
You could also measure the caps as they all have 10% tolerance- on small caps like this value can be a little lower or higher on e-lytics usually higher.
Many times you can adjust a resistor
to make turn over frequency the same.Though most likely it won't matter in this circuit.
Also if you are not pleased you can later change the cap to required value.
As always best to use the ears.

Kind regards
BJ
