Use of the industrial equipment under stricter temperature environment has increased. Smart meters, in particular, are expected to operate outdoor in cold-weather environments, and the capacitors used in a backup power supply are required to operate in the same low temperature. In general, the low temperature guarantee of the company’s conventional radial lead type electrical double layer capacitors was limited to -25 degree C since the conductivity of capacitors reduces and the internal resistance increases under low temperature environment.
However, this product achieved a guaranteed operating temperature of -40 degree C through the development of this new electrolyte, and it can satisfy the ANSI standards of the United States. Therefore, this product is suitable for equipment installed outdoors such as smart meters as well as automotive applications in cold weather.
