AO-CAP Aluminum Polymer Capacitor


What is the operating life for an AO-CAP capacitor?


AO-CAPs, or Aluminum Organic Capacitors, use a  solid conductive polymer as their counter electrode. There is no electrolyte in the finished capacitor. Unlike traditional “wet” style aluminum electrolytic capacitors, the rated lifetime is significantly longer.

Please note that many times customers mistake the “Endurance” or “Lifetime Test” for AO-CAP as equivalent to the estimated life-time of an a wet Aluminum Electrolytic. In the case of AO-CAP, these qualification tests. These test conditions are similar to other dielectric’s test conditions.
