Hi,
We wish to calculate the ESL of the following 1nF, 1kV capacitor...
RDER73A102K2M1H03A
The attached shows an impedance vs frequency graph.
We wish to calculate the ESL at 2.8MHz, and with DC Bias of 600V on it. (it is a capacitor connected from drain to ground in a flyback converter.)
The ESR at 2.8MHz is 1.1R
The Capacitance at 600V is 600pF
So using Z = SQRT( A^2 + B^2).
...where A = 1.1R and B = [wL - 1/(w*C) ]
...we get ESL = 8.8uH.
This seems very high for a ceramic capacitor?
