SAMWHA Electric

SAMWHA - South Korea

SAMWHA Electric, part of the SAMWHA Group, is a leading manu­facturer of passive components. Electrolytic capacitors, ULTRACAP, Conductive Polymers Hybrid Capacitors are just a part of the wide range of products. It is therefore not surprising that the capacitor specialist received the World Class 300 Company award in 2018. Continuous improve­ment in quality and quality assurance, as well as heavy invest­ment in production and inter­national sales, have led the company to a global market position.

CAPCOMP is the official distributor and representative of SAMWHA Electric.

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
