LIFE CALCULATORS AND PERFORMANCE MODELING

Use our modelers to determine Life, Reliability and Impedance characteristics, and to generate SPICE and S-Parameter models of key capacitor types.

 

Screw-Terminal Aluminum Electrolytic Capacitor Lifetime & Reliability Calculator

Calculating the estimated lifetime of your aluminum electrolytic capacitor is made easy using this interactive tool.

Based on your specified operating conditions of voltage, ripple current, heatsink characteristics, airflow and ambient temperature, this model calculates the internal hotspot temperature and expected lifetime, reliability and failure rate. Change the operating conditions or capacitor type to assist you in choosing the right capacitor for your application.

Aluminum Electrolytic Impedance Modeler / SPICE Model Generator

Covering 26 of our most popular series of aluminum electrolytic capacitors—

including FlatPack, Screw Terminal, Snap-In and Plug-In types— our Aluminum Electrolytic Impedance Modeler / SPICE Model Generator will create interactive plots of capacitance, ESR and impedance versus frequency and temperature. It will also generate a Pure SPICE netlist that can be pasted into your circuit modeling software.
