Development of Radial Lead Type Supercapacitors 2.7V Products DKG Series
Nippon Chemi-Con has developed the DKG Series, which achieves higher withstand voltage and smaller size compared to radial lead type supercapacitors DKA Series. The DKA Series has been used in automotive power supply backup applications and has received many inquiries.


The DKG Series has a new material structure for higher withstand voltage and smaller size. The rated voltage has been increased from 2.5V to 2.7V, and the size has been reduced by up to 20%.
This will help optimize the design of equipment as a backup power supply for unlocking electric doors, shift-by-wire, EPS (electric power steering) and even drive recorders.
As before, acetonitrile (AN) solvent, which may cause cyanide gas, is not used as electrolyte. AN has a low viscosity and makes lower resistance possible by using them as electrolyte for supercapacitors. Therefore, it is widely used by manufacturers overseas. However, the DKG Series has a low resistance equivalent to or higher than that of products using AN.
