Re: [TCML] Sec design trade-offs and considerations



Hi Matt,

I suspected as much, though was unsure what was pauls motives behind what he said.

There probably is a frequency, though have no idea what it is, suspect in the low MHz range somewhere. At least that is about the figure yellow rolled caps have... I think..

Hi Chris,

Every capacitive device has a small amount of inductance and resistance.
Likewise, every inductive device has a small amount of capacitance and
resistance. Therefore, every such component has a frequency at which its XL = -XC. If the resistance is negligible, the component will tend to oscillate at this
frequency.

Hope this helps,

Matt D.

Hi  Paul,

Not sure what you are getting at with self res freq ? I don't know what it
is and doubt I would be able to measure it. The caps are  supposed to have
zero L&R though think that's a bit of a lie in the  datasheet as they must
have *some*.

They are all flat plate caps,  over 200 of them in parallel. Any problems
there would probably be self inflicted with all the wiring, though they are
fixed between 2 large  sheets of copper sheet and all kept as physically
close as possible. I can  send you some images off list if needs  be.

Chris
