<font face="Arial">It is frustrating that there are no standards out
there. For what it is worth, there are a group of manufacturers
who a<font face="Arial">re supposed to be working to<font
face="Arial">gether to form a 'EuroSynth Body' but I don't
think it is moving anywhere at the moment and is probably far
too late in the day to define some 'proper' standards and will
most likely have to try and define the existing figures in to
a formal document so that we at least have <font face="Arial">some
common ground to work with.<br>
<br>
<font face="Arial">If you don't use ferri<font face="Arial">te
beads then you should use a resistor of between 10R and
22R.<br>
<font face="Arial">The diodes as shown will force the
power rails in to an 'out of specification' area so
should not be used <font face="Arial">(</font>certainly
not in that configuration)</font><br>
<font face="Arial">10uF is ample especially given the
number of modules</font> in any system and the
inability for some supplies to handle large inrush
currents<br>

<div>This is what I plan to use. Maybe my pin umbers are off. I

<div>It seems like I should just not use it?</div>

<div>Resistor</div>
<div>Don't use it?</div>
<div><br>
</div>
<div>Ferrite Bead</div>
<div>Some people are telling me outside this list that ferrite
is more for digital stuff and that the capacitor should be
fine. If I don't use the ferrite then should I use a resistor
instead?</div>
<div><br>
</div>
<div>Capacitors</div>
<div>Only use the larger one (I use a 0.1uF bypass cap at each
IC anyway). Some say increase and some say decrease. In
non-modular stuff I usually use larger ones, so I am leaning
towards 22uF.</div>
<div><br>
</div>

</div>
<div>I wish that there was a standard for this so I knew what to
do :(</div>

</span>Some years ago, Tony Allgood mentioned that he had to
switch<br>
from 22 to 2.2 µF per rail because the surge current from
lots<br>
of 22 µF capacitors in parallel made certain Power-one
supplies<br>
misbehave on power-up. But that was with ferrite beads, not<br>
resistors.<br>
