How to Choose Aluminum Electrolytic Capacitors: Ripple Current, ESR and Lifetime

Aluminum electrolytic capacitors are the workhorse of bulk energy storage and filtering in power supplies, motor drives and LED drivers. They offer high capacitance per dollar, but they are also the most common wear-out part on a board. Picking the right one comes down to three numbers: ripple current, ESR and rated lifetime. Ripple current Every... Weiterlesen: How to Choose Aluminum Electrolytic Capacitors: Ripple Current, ESR a…
