2. When selecting an output capacitor, consider not only the ripple voltage but also the ripple current to prevent risks caused by
using a capacitor outside its specifications. A Γ-shaped filter circuit can be used to reduce the ripple current of an output
capacitor. For details, see the ADF500W Power Module Application Guide.
