Wrong Voltage Noise Section

I know this has been discussed very often.. I only get 50mv at PIN1 U24 all resistors are correct in the noise section.. double checked it :) I tried everything.. R127 with 47K .. with 4,7K .. adjustable resistor..even if i go under 1k... nothing ;( where is my fault? the only what i did diffrently ...

Negative Voltage in Noise Section? U24 PIN1

I have read many threads about the 130mv at PIN1 U24 in the noise section.

I got around 240mv but negative ?! so now .. is this a measure fail or what? always -240 - -280 mv (depends on tm4)
i checked all my capacitors .. they are right.

any ideas?

best

Film-Capacitor in Noise Section

Heyho,

Just soldering the Noise Section.. Now i am at the point with the capacitors
Its about the C33 with the value of 18n
in the mouser bom there is only a pack (3x) 1,8n (0,0018uf)

The mouser nr is 647-QYX1H182KTP

So the BOM is wrong or do i miss something?

best!

Re: YOCTO 1.0 enclousures - LAST BATCH

Re: Capacitor in PSU wrong?

Thanks! That was my first thought... but i was not sure :)

one moore question maybe...
In the Noise Section is the Capacitor C31 (50V1uf) But in the BOM is only a 50V 10uf .. hmm..
or am i blind?
can i use the 50 V 10uf ? i dont guess...or?

Capacitor in PSU wrong?

Hey,

I am just sort all Parts from the Mouser Bom...
Probably a beginner question :) The Building Guide says in the Powersupply that i need 1 680uf 35v capacitor...
But in the BOM is a 680uf 25v capacitor.
Can i use it anyway or would it be better to get a 35v version?

thanks in advance!
