Capacitor Table
PTV03020W
SLTS243A – FEBRUARY 2005 – REVISED OCTOBER 2007
Table 1 identifies the characteristics of capacitors from a number of vendors with acceptable ESR and ripple
current (rms) ratings. The recommended number of capacitors required at both the input and output buses is
identified for each capacitor type.
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) Capacitor Supplier Verification
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
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) Total capacitance of 660 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.
