Power Supply Design
Paralleling Capacitors
Early life failures can occur as a result of using two different capacitors. During the design of a power supply, careful consideration must be given to the equivalent series resistance and ripple current, as well as the total output capacitance. The capacitors should be as identical as possible, with the same ESR and ripple current capacity.
