quest for a cap....

CBS240 · 3rd January 2010, 06:13 PM

Hi

I'm having trouble sourcing a 200nf polystyrene cap. I know they exist, but any ideas where to get some? I'm in the process of drawing a PCB and it would be nice to find some so I can be sure the dimensions are correct.

Thanx

That's HUGE for a polystyrene

IIRC, Surplus Sales of Nebraska had some last fall.

Cheers!

cool Thanks.

I think I can use 100nf, still huge for polystyrene but they seem to be more available.

Edit> I found a source here, will have to check it out.

My math is a little off could you tell me what value this is in uf. as I think I might have in Styrene and Tin foil with copper leads.

200nf would be 0.2uf

I only have Styrene in .1uf and .22uf in 400 or 600v
These are fairly large with axial leads. Can you use two .1uf in parallel?
