Supercapacitors DLCAP™
Supercapacitors, also known as Electric Double Layer Capacitors, are noted for their high current charge-discharge capabilities and excellent cycle life compared to traditional rechargeable batteries. They are increasingly utilized in applications prioritizing energy conservation and low environmental impact, such as hybrid and fuel-cell vehicles.
Supercapacitors store energy through the physical movement of ions to the surface of activated carbon, unlike conventional capacitors that use a dielectric. This results in high power density and efficiency, with over 95% output efficiency.
Supercapacitors exhibit low degradation, can withstand millions of charge-discharge cycles, and are environmentally friendly as they do not contain heavy metals. They are safe even under irregular conditions, such as short-circuiting.
Nippon Chemi-Con produces Radial Lead and Screw Terminal types of DLCAP™ supercapacitors, utilizing aluminum foils with electrodes wound into a roll to achieve high capacitance and low resistance through high-density electrode manufacturing technology.
- Operating Temperature: -40℃ to +65℃
- Capacitance Tolerance: ±10%
- Load Life Test: Capacitance change ≤±30% after 2000 hours at rated voltage and temperature.
For the DKG series, the rated voltage is 2.7V with a capacitance of 50F, and internal resistance ranging from 16.0 to 19.2 mΩ.
Supercapacitors are suitable for electricity backups, battery assistance, and short-term power storage. They are also ideal for automotive applications such as kinetic energy recapturing and low-temperature engine cranking.
The products comply with RoHS2 and ELV directives, ensuring they are environmentally friendly and free from hazardous substances.
