New size of Conductive Polymer Hybrid Al ECAPs

Samwha Electric has added a new size (⌀6.3×5.8L) to the YH and YM series, Con­duc­tive Poly­mer Hybrid Alu­minum Electro­lytic Capa­citors, which have life time of 4,000 hours at 125℃ now.

YH and YM series have low ESR and excellent sta­bility even at high tem­pera­tures due to con­duc­tive poly­mer and opti­mized electro­lyte. This series was de­veloped for the auto­motive electro­nics and indus­trial equip­ment markets that require high reliability.

Summary of key features

  • Superior ripple characteristic (Ultra low ESR)
  • Superior tempera­ture charac­teristic
  • Short circuit risk solution (Failure mode: Open)
  • Set miniaturization
  • Excellent moisture resis­tance
  • No capacitance reduction by DC BIAS
  • Long life & High reliability
  • AEC-Q200 compliant


  • ISO14001/IATF16949 for Auto­motive Certi­ficates
  • Specification (“YH” and “YM” Series)

Also new VX servies with Al ECAPS (radial / snap in)

VX series is newly intro­duced along with VQ series, which is a special series for high tem­pe­rature charac­teristic. Main target appli­cation is auto­motive market, as it is AEC Q200 compliant.

At 150℃, previously maxi­mum load life was 1000 hours but with the new series load life is longer up to 2000 hours. Further­more, one of the key snap in “HE” series (see webshop) has been upgraded with higher vol­tage up to 600V. In sectors such as home appliance and industrial, such 600V high voltage could provide various options for custo­mers as this was required more con­stantly in the market.

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
