Supercapacitors & Ultracapacitors

SuperCapacitors VinaTech EDLC

The term supercapacitor and ultracapacitor are interchangeable. They are both considered EDLCs which are electric double layer capacitors. Supercapacitors have no chemical reaction like a traditional electrolytic capacitor and can last many years with the proper design guidelines. EDLCs are power dense devices, unlike batteries; which are energy dense devices.

Supercapacitors are available in different industry standard packages: coin cell, small cell leaded, small cell screw terminal, large cell screw terminal, large cell weldable and in module configurations. Marsh Electronics carries a broad line of supercapacitor/ultracapacitor vendors and can provide all of the above packages. Typical applications for supercapacitors are back up power, regen braking, peak power assist and quick charge/discharge.

Marsh Electronics offers one of the broadest selections of supercapacitors and ultracapacitors in the industry. Marsh represents the leading supercapacitor 2S Module Series and ultracapacitors manufactures in the electronics industry.
