What is .01 microfarads in picofarads?

Question

I have a specification calling for a .01 microfarad capacitor, and my little ceramic disk capacitors are rated in picofarads such as 1 picofarad, 10 picofarads, etc... Which one do I use?

My circuit (a 555 timer) isn't working and I'm using a 1 picofarad capacitor where is calls for a .01 microfarad, is this correct? I'm just getting somewhat confused.

Thanks!

Answer 1

A picoFarad is 1 millionTH of a micoFarad, so it's pretty small.

0.01 microFarads would be 10,000 picoFarads

The 555 won't run that fast, which is why the small valued (pico) capacitors aren't working.


Now... to confuse the issue more... The prefix in between micro and pico is NANO. 10 nanoFarads is equal to 0.01 microFarads. Maybe you were thinking of a nanoFarad instead of a picoFarad?

Capacitors are often labled very confusingly by manufacturers - They are hard enough to work out the right values as it is. Even professionals frequently make mistakes.

1,000,000,000,000 picofarad (pf or occasionally uuf) =
1,000,000,000 nanofarad (nf) =
1,000,000 microfarad (uf or occasionally mmf) =
1,000 millifarad (mf) =
1 farad (f)

So a 0.01 microfarad
= 10 nanofarad
= 10,000 picofarad (which just to make things even worse, I've seen listed as "10K pf")

A 1 pf is just too low, the circuit might be working, but just oscillating so fast, it looks like it is on (or off) all the time?

Anyway, I hope this helps a little?!

Good luck sorting the circuit out!

Answer 4

Picofarad To Microfarad

Answer 5

1micro= 10 to the power minuis six
1nano = 10 to the power minus nine
1 pico = 10 to the power minus twelve
or 1 pico = 1/ 10 to the power twelve
1 pico = 1/1000000000000
1 micro = 1/1000000
you are using .01 micro that is 1/100000000
still 4 zeroes are left with!!!!!

Answer 6

Picofarad

Answer 7

Wow ... a 1 pf capacitor ??? just connecting to the package has more than that between the two terminals with no internal structure.
