Circuit Board on Maxtor 1 touch

[toxicmonkeylove]

I need to know what the values of C417 & C404 capacitors. They are
missing. on the circuit board inside the maxtor 1 touch external drive.

Thanks for your time

Likely they decided that they arent necessary and are just extra decoupling caps.

Why do you think they are needed? If you think they are needed,
you should be able to estimate a value....

I believe that they are missing cause there is evidence of legs
soldered to the board.
i know they are yellow block type caps by a picture i've seen showing
them, but it was not detailed enough to see the values.

thanks

So someone ripped them out? Did you find this device in an
electronics trash pile?

SMD or through-hole?

Do you also think that posting the same reply 3 times is better than once?

it is a customers unit, and should be thrown in the trash...

And you are the unlucky person that has to repair it? It think
I get the picture.

Well, SMD and yellow usually means electrolyte capacitor.
Unless very expensive, not larger than 100uF or so. 16V
is enough for computer usage.


You probably don't have a second unit to compare. Best guess is
then to find out hwat they are supposed to do and use the physical
dimensions in addition.

If these are buffering for the supply voltages, something like
100uF is also likely the sensible choice. Do not make them
too large, since that can cause instabilities in switching
PSUS of the external "brick" type.

They do not need to be low-ESR, since HDDs have low-ESR bypass
capacitors (usually creamics) anyways.

SMDs dont have legs.

Hi Rod, WHY do You think decoupling caps are not neccessary?
Have You any ideas on electronic requirements?

Hi toxi..., rubbish!
Typed legs on a motherboard does not identify that they should
be used on that specifique version of Your motherboard!
They will be used on another version.

Never said that. I was just suggesting that SOME of the caps
may not be necessary if it was supplied by Maxtor like that.

It isnt that unusual for some stuff to have provision for
EXTRA decoupling caps on the pcb which dont get included.

Have You any ideas on electronic requirements?

Fraid so, likely since before you were even born thanks.

You've no idea when I was born!
So any reflections on this are obvious and rubbish!
And WHAT has this to do with the subject?
