Default Require .1UF are there any alternatives

im making this project (a pic programmer)
http://www.bobblick.com/techref/proj...g/picprog.html
it requires a .1uf ceramic capactor but i canf find one at home what
otehr alternatives can i use if any

i ahve a .01 greencap

# 50V NPO 1.5pF x 1
# 50V NPO 3.9pF x 1
# 50V NPO 4.7pF x 3
# 50V NPO 5.6pF x 3
# 50V NPO 8.2pF x 3
# 50V NPO 12pF x 10
# 50V NPO 15pF x 2
# 50V NPO 47pF x 5
# 50V NPO 56pF x 5

# 50V Y5P 0.0022uF x 2
# 50V Y5P 0.0033uF x 5
# 50V Y5P 0.0056uF x 3

and the following
* 470uF 16V x 5
* 470uF 25V x 1
* 330uF 25V x 1
* 220uF 25V x 2
* 220uF 16V x 2
* 100uF 16V x 8
* 100uF 25V x 6
* 47uF 25V x 4
* 33uF 35V x 3
* 33uF 16V x 15
* 4.7uF 50V x 4
* 2.2uF 100 x 4

but i doubt they would be any good

thanks for your help

Any electronics parts supplier should be able to supply you with the
required Ceramic Capacitor without guessing.

Hi Nathan
Your selection of capacitors is not very useful since 0.1uF =3D =
100,000pF
I think you have 3 choices....

1. Search some old PCB,s or electronic equipment for a 0.1uF which you =
can remove

2. Use 2 bits of insulated wire twisted together. You would need a DVM =
or something which could measure capacitance to check it - also for =
0.1uF depending on the thickness of the wires it could be a foot or more =
long !

3. Let me know your address and I will post you one.

No, much much longer. That method isn't really good for more than a few pF
and we are after 100,000pF here.

It seems it's just a bypass. Use the .01. If it doesn't work, then
order a .1 from practically anywhere - it's about the commonest
bypass capacitor in the known universe. While you're waiting for
the right part to arrive, put these two in parallel:

# 50V Y5P 0.0056uF x 3

* 2.2uF 100 x 4

but i doubt they would be any good


Based on what?

Good Luck!

There are five 0.1 uF capacitors in your schematic. They are all bypass
capacitors. If you have enough 0.01s, use those instead or the 0.0056s.
The circuit will probably work without any of those capacitors, but you
should add them just to be sure you don't get oscillations.

You can buy a bunch of the 0.1s ($5 or so for 100) from Mouser or Digikey if
you are in the U.S. Get "monolythic ceramic". 50 volt will do.
