(1) N/R – Not recommended. The voltage rating does not meet the minimum operating limits.
(2) Total capacitance of 540 µF is acceptable based on the combined ripple current rating.
(3) Ceramic capacitors are required to complement electrolytic types at the input and to reduce high-frequency ripple current.
