Cornell Dubilier Life and Temperature Calculators

Screw Terminal Applet

Cornell Dubilier's Screw Terminal applet can automatically page through CDE's catalog ratings and fill in the rated capacitance, full-can capacitance and typical ESR after you've entered the capacitor type, case size and rated voltage. It even gives you the option to fill in your capacitor's ESR values at your operating temperature and ripple frequencies if you have your own data.

Impedance Modeling Applet

CDE offers Spice models of many wet aluminum electrolytic capacitors. Cornell Dubilier has an online impedance modeling applet that allows the user to select any standard catalog part number among 16 types. The capacitance, ESR, and impedance are then graphed versus frequency at several temperatures. A Spice simulation program listing is available and this model is readily cut and pasted into a Spice simulator.
