Product Description
Supercapacitor from VINATech Radial EDLC's face challenges when exposed to a combination of high temperature and high humidity over an extended period of time that is outside the defined operating limits.
As a consequence, a black substance develops as a typical characteristic at the (-) pin, which irreversibly destroys the conductor paths located in the vicinity of the component.
We also speak of the betting phenomenon.
This phenomenon is manufacturer-independent, to the best of our knowledge all manufacturers are affected.
This is a fundamental technological problem.
After years of intensive research, VINATech has developed a permanent shutdown measure for its 2.7 V and 3 V supercapacitors, for which a patent has been applied for.
After more than one year of continuous cycle tests at 65°C and 90% relative humidity, no wetting was detected.
The WEC series is pin-to-pin compatible to the well-known VEC series and other super capacitor series.
