Please, could you help me identifiying which component is the transparent
cover one shown here:

Exactly. The H is the tolerance, and I believe it's 2 percent. |

Could be one of those thermal fuses like in a hair blower.

Yes, and you have to watch for hairline cracks in old polystyrene
caps.

Thanks a lot.
So, to sum up, it is a 1000pF polystyrene capacito at 33 volts and 2%
tolerance.
Is it ok?
How could I fine some at an on-line store?
I mean 50 or 100 could be ok.
Thanks

I don't believe anyone said it was 33 volts. The voltage is not
important as long as it's above the supply voltage. You will probably
have a hard time finding a 1000 pF, 2% polystyrene at any voltage,
because that's a close tolerance. So if it's a 100 volt or 250 volt or
whatever, use it as long as it's above the supply voltage.
Mouser and Digi-key are two online distributors.

Are you saying it doesn't matter the voltage?
I mean, this capacitor was put in series with other resistors in a hi-end
interconnect cable connecting the screen to the center conductor (the screen
appeared to be also connected to the outer conductor).
Do you think the voltage of the capacitor doesn't matter at all?
Thanks

Yep, so he says. And he is completely right. As long as the capacitor
can handle the voltage, it is not really interesting how much more
voltage it can handle... kinda like wire insulation. If you need
insulation that can take 12V, you don't bloody care if it can take 100V,
since that means it takes 12 fine...

Well, you were extremely clear.
Thanks a lot.
Just one question more.
Someone says we are talking about 33pf and someone about 1000pf aka .001uf
aka1 nf.
Which version do you suggest?
The 33pf or the 1000pf one?
The one that is correct... Look up in the schema. |
But, a capacitor that can handle higher voltage, is physically bigger,
so check if it fits your application

Higher voltage gives more safety margin. As long as it will fit in the
same space, use it.

We thought we made that abundantly clear to you. The 102 stands for 10
with two zeroes after it. That's 1000 pF AKA .001 uF AKA 1nF. the H
stands for 2 percent. Wherever you got the other 33pF crap, forget it.
It's time for you to quit asking questions and get your butt out the
door and hunt one of them down. Go to it. |
