Hi Guys,
under:
you can find some basics about the 'ESR' of a Capacitor.
A formula is shown describing the 'ESR' as: Rp/((2*Pi*f*Cp*Rp)^2+1) and the 'ESC' is : Cp+1/((2*Pi*f*Rp)^2*Cp)
I guess, that the basic model looks like this:
|| __________ __________
--------o----------||--------o-----|__________|-------|==========|---- | || Cp | Rs Ls | ___________ | |---|___________|----| Rp
My first Questions:
Is the formula for the ESR correct?? Paralleling Cp and Rp should result into an impedance of: Rp/sqrt(1+(2*Pi*f*R*C)^2)
Or NOT????
My second Question:
I don't have a glue how the 'ESC' has to be calculated at all. What is the idea behind that?
So long
