can someone please verify if these capacitors will work?

https://www.tselectronic.com/nte/radial_cap3.html .1mf (100 nf)

https://www.tselectronic.com/nte/ceramic_cap.html 1 pf

thanks

These are electrolytic capacitors, you can choose 1uf from these. Not 100nf!

https://www.tselectronic.com/nte/ceramic_cap.html 1 pf

There are no 1pf capacitors in the schematics. You can choose 22pf capacitors from this list.

are you sure (silly question:) ) i'm doing the all in one 2.5, and looks like there are 2 100nf caps on right after a short jumper next to the 1hm (think this is the choke) and another right by the 15pf cap and the 12mhz crystal.

Yes, I'm sure you won't find 100nf electrolytic capacitors. You have to use ceramic capacitors for 100nf.

one more question , since i'm using what appears to be a polarized capasitor, what would the orientation be? there are no poloarity markers.

thanks

- to minus/ground, + to Vcc/+5

ok i lied...one more...

are you sure it's 1uf and not .1uf? please forgive me, i just don't want any more to go wrong with this project.

No offence but really, if you keep asking the questions this way, you'll be getting similar kinds of answers. Yes, I'm sure 1uF is not 100nf.

Half of the right answer is in the right question.

I do apologize if my questions were worded oddly or not clearly; i was at work so i was just firing off quick questions...what i was trying to ask was if the 100 nf = .1 uf or if it does in fact equal 1uf as stated in the original reply; not that i doubt you i just wanted to double check as i had contradictory information and wasn't sure if a decimal was left off. I just want to be certain before soldering booting and possibly screwing something up.

Thank you;

I never said 100nf is equal 1uf, even in the original reply.

Point me to th contradictory information and I'l either correct it or remove it.

and wasn't sure if a decimal was left off. I just want to be certain before soldering booting and possibly screwing something up.

Just follow schematics. Anything above or equal 1uf must be electrolytic capacitors, everything below, including 100nf=0.1uf must be ceramic capacitors.
