Capacitors - Designs & Types

As energy storage devices, capacitors are indispensable components in electrical engineering. They are used, for example, when voltages need to be filtered or buffered or when load peaks need to be absorbed. Which technology is used depends on the respective application.

We will be happy to advise you on which solution is the best for your application. You can choose from a wide range of different capacitor types: electrolytic capacitors, Kerkos, tantalum capacitors, film capacitors and the powerful ultracaps. When choosing your capacitor solution, you can rely on reputable international manufacturers who ensure high quality and long component life.

Ultracaps / Supercaps / EDLC

Electric double-layer capacitors EDLC are also colloquially referred to as supercapacitors, supercaps or ultracaps. Designations like Boostcap, Goldcap, Pseudocap, etc. represent brand names.

EDLCs are manufactured in various sizes and designs. Designations such as "small - medium - large" are individual manufacturer specifications. Over the years, however, the following categorisation has become established:

  • up to 100 F are small cells (3-25mm diameter)
  • from 100 F to 500/600 F we speak of medium cells (30-37mm diameter)
  • 600F and above are large cells

In addition, it is also possible to configure ultracaps as modules.
