Ultracaps with fine differences

ULTRACAPs only become capacitors at the end of the manufacturing process, through so-called "AGEING" . This is a somewhat unfortunate choice of words, because ageing does not yet take place here, but rather "birth". The German expression "Formieren" ("forming") is more appropriate, for once, because by applying a voltage, the so-called Helmholtz layers are formed and the double layers of the capacitor are created. During this process, all cells are also measured and thus 100% tested. The capacitors are marked with a lot number.

Lot numbers enable traceability

  • Year of manufacture
  • Month of manufacture
  • Week of manufacture
  • Component

The "lot numbers" are an encoded data code and the manufacturing batch to ensure traceability according to IATF16949.

The coding of the lot numbers differs from manufacturer to manufacturer, but can be requested from us if necessary.

Why are components like ultracaps called different names?

The variety of terms is explained by the English-language terms commonly used in the electronics industry, which are often mixed with German terms or used synonymously. In some cases, manufacturers have also introduced artificial terms to better distinguish themselves from competitors. Here are the most important examples:

Double layer capacitors (DSK) are referred to synonymously as:

  • EDLC (Electric Double Layer Capacitor)
  • Supercapacitors = Supercaps
  • Ultracapacitors = Ultracaps
  • Goldcap™ [Panasonic]
  • Boostcap™  [Maxwell]
  • Greencap™  [Samwha]
  • PURIXEL™  [Pureechem] for supercap cells
  • PURETRON™  [Pureechem] for supercap modules
