Capacitor Measurement and Modelling Basics (Bode 100) - Phil's Lab #150
Measurement of SMD capacitor characteristics (ceramic, tantalum, electrolytic) using a Bode 100 with an impedance adapter. Discussion on capacitor modelling basics, measurement technique, pitfalls, calibration, and simulation. Acquiring impedance vs frequency curves, extracting capacitance, ESR, and ESL, and using that information in a SPICE model.
