Electrolytic Capacitor Life Calculator
The Electrolytic Capacitor Life Calculator determines the estimated lifetime of an electrolytic capacitor. Electrolytic capacitors have a limited lifespan primarily due to the degradation of the electrolyte over time. The lifetime calculation is based on load life rating, maximum voltage rating, operating voltage, maximum temperature and ambient temperature. This calculator is ideal for engineers and designers to select an appropriate electrolytic capacitor for a specific application.
Enter the value of L1 - Load Life Rating, Vr - Maximum voltage rating of capacitor, Vo - Operating voltage of application, Tm - Maximum temperature rating of capacitor and TA - Ambient Temperature of Electrolytic Capacitor
This calculator is based on Arrhenius' Law of Chemical Activity which states that the capacitor's life doubles for every 10oC decrease in temperature. The calculator provides insight into the internal hotspot temperature, expected lifetime, reliability, and failure rate of the capacitors under different operating conditions.
