Can I use an electrolytic capacitor?

Usually an electrolytic capacitor can be used here. KEMET’s technology roadmap ensures aluminum electrolytic solutions to meet the evolving needs of the Energy Harvesting sector. KEMET’s High CV Screw Terminal and Snap-In series are available in 85°C and 105°C.

Are electrolytic capacitors peer reviewed?

Preprints and early-stage research may not have been peer reviewed yet. Due to their high specific volumetric capacitance, electrolytic capacitors are used in many fields of power electronics, mainly for filtering and energy storage functions. Their characteristics change strongly with frequency, temperature and aging time.

How to choose electrolytic capacitors for energy-harvesting applications?

When choosing electrolytic capacitors for energy-harvesting applications, the lifetime of the device is a key parameter to consider. Equipment is often installed in remote locations and expected to operate for long periods with zero maintenance. Remotely installed devices may also be exposed to extremes of temperature.

Which physics can store energy in an aluminum electrolytic capacitor?

Simplified diagram of the constitution of an aluminum electrolytic capacitor consisting of aluminum electrodes, an alumina dielectric and an electrolyte. The only physics that can store energy in a capacitor is electrostatics, allowing rapid and reversible processes.

Do electrolytic capacitors need maintenance?

There are many studies on the failure modes of electrolytic capacitors, and mainly aluminum electrolytic capacitors. Indeed, from the understanding of the mechanisms and failure modes of a capacitor, it is possible to apply a maintenance in order to know the remaining lifetime of the component.

What are the different types of energy storage capacitors?

There exist two primary categories of energy storage capacitors: dielectric capacitors and supercapacitors. Dielectric capacitors encompass film capacitors, ceramic dielectric capacitors, and electrolytic capacitors, whereas supercapacitors can be further categorized into double-layer capacitors, pseudocapacitors, and hybrid capacitors.
