(1) Capacitor Supplier Verification
1.Please verify availability of capacitors identified in this table. Capacitor suppliers may recommend alternative part numbers because of
limited availability or obsolete products. In some instances, the capacitor product life cycle may be in decline and have short-term
consideration for obsolescence.
RoHS, Lead-free and Material Details
2.Please consult capacitor suppliers regarding material composition, RoHS status, lead-free status, and manufacturing process
requirements. Component designators or part number deviations can occur when material composition or soldering requirements are
updated.
(2) N/R – Not recommended. The voltage rating does not meet the minimum operating limits.
(3) Total capacitance of 540 µ F is acceptable based on the combined ripple current rating.
(4) Ceramic capacitors may be used to complement electrolytic types at the input to further reduce high-frequency ripple current.
