[SI-LIST] Differential Impedance calculation

Hello,=20

Did someone knows how to calculate differential impedance with two =
different single ended Impedances?
I measure impedance of differential line with TDR (single ended probe) =
and the two impedances are different.

Thank you for your help

Hello,
To evaluate capacitor reliability in THB condition,  a circuit using =
power supply and limiting current resistor connected to the capacitor =
is used.  If a short occurs between the capacitor pin, is the current  =
will exceed the resistor limited current for a short period of time ?
