Capacitor selection guide

The Maxcap® electric double layer capacitor standard products series offers a wide range of product geometries and electrical characteristics from which to choose.

The major design considerations in selecting a Maxcap® electric double layer capacitor for a given application include the load characteristic, the allowable voltage drop, required backup time and available board space.

To help you select the best Maxcap® electric double layer capacitor for your application the table below summarizes the characteristics of each product series.
