Tantalum capacitors cannot be well modelled by means of the commonly used series R-L-C network, so other equivalent circuits are required when an accurate model is needed. Proposed is a simple and systematic modelling procedure for tantalum capacitors. A canonical passive network (minimum number of elements) is synthesised from the capacitor impedance magnitude. The model is validated using commercial capacitor data from a manufacturer's catalogue.
