Note: This is not an extensive capacitor list. Capacitors from other vendors are available with comparable
specifications. Those listed are for guidance. The RMS ripple current rating and ESR (at 100 kHz) are critical
parameters necessary to ensure both optimum regulator performance and long capacitor life.

(1)
N/R – Not recommended. The voltage rating does not meet the minimum operating limits.
(2)
Total capacitance of 540 F 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.
