Zhangkun,
Dependent on the dielectric material, the capacitance will change more or
less with bias voltage. This information should be available from the
capacitor manufacturer. It is reasonable to assume that the series
resistive loss and inductance do not vary noticeably with bias voltage.
Regards,
Istvan
