Digital Noise cap

Digital Noise cap

2007-05-18 by Andrew

The only 47pF cap I have is a ceramic (non-polarized). On the Digital
Noise PCB, the labeling clearly shows a polarized Electrolitic
capacitor in that spot.

Will the ceramic one work, or am I just asking for trouble by using
it...?

thanks :)

I'm not sure where you see a 47pF cap. There is a 0.47uF eletrolitic in
there though (470nF).

Oops, yeah that's the one I mean. Don't have it in front of me here
at work :)

I have the right number of F's, but the wrong type. Is there any
chance that the ceramic will work or do I need to go shopping?

thanks for any thoughts!
Andrew

Substituting an electrolyte for a non-electrolyte can generally be
considered safe, if you're really sure it's the right value.
But substituting it with your 0.47 _p_F ceramic probably won't work as expected.

only if the electrolytic is nonpolar/bipolar. subbing a unipolar cap
in a NP/BP application won't work.

right. especially because the one in the design is unipolar.

(IMHO)

Just use a 1uF electro. It's only the power on reset circuit.
