How many types of capacitor internal resistance are there
Real ceramic capacitor can be modeled by an ideal capacitor (C) connected in series with internal resistance (Resr) and inductance (Lesl). There is also R-isolation in parallel with C, but unless you go over capacitor''s rated voltage it is unimportant for power decoupling applications. simulate this circuit – Schematic created using CircuitLab - Download [PDF]
