Electric Double Layer Capacitators
Double Layer Capacitors
The Maxcap® electric double layer capacitor standard products series from Ohmite 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.
In order to enable you to select the best Maxcap® electric double layer capacitor for your application, the table below summarizes the characteristics of each product series.
