Improved distributed model for capacitors in high-performance
Time-domain and frequency-domain measurements show that a simple lumped RLC model for a multilayer ceramic capacitor is inadequate, overestimating high-frequency impedance by a factor of five. A lossy transmission-line model works better, and is improved by placing incremental resistance in series with the incremental capacitance. Refinements of this model are

4 FAQs about [High frequency ceramic capacitor model]
What is a high voltage ceramic capacitor?
High voltage ceramic capacitors are particularly suitable for applications requiring a high voltage (from 10 to 150 kV). They achieve very good performance under pulse and discharge conditions. Ceramic capacitors are suitable for such high voltages while reactive current remains low. Various disc types cover a wide range of capacitances and voltages.
