The electrostatic capacity is 14mF. A chip type tantalum (Ta) electrolytic capacitor of the same size has an electrostatic capacity of 30 times or more. Further, by using an organic solvent in the electrolytic solution, it can be used in a large voltage range of 0 to +2.6 V. Therefore, there is no need to protect the circuit from overcharging and overdischarging. Moreover, it can be charged to a 90% capacity for rapid charging in 1 minute, and a discharge capacity of about 90% or more when the load current is 1 to 100 μA.
Sample shipments began in June 2008. Mass production began in October 2008. Strive to sell 20 million monthly sales in 2009.
Seiko Instruments will introduce a chip-type electric double layer capacitor "CP3225A" with a 3.2 mm x 2.5 mm x 0.9 mm outline. Compared with the conventional standard coin type products, the electrostatic capacity per unit volume is increased by 50% by eliminating the dead zone. Moreover, by integrating with the terminals, the package area is reduced by 1/5. It is made of a ceramic package with excellent air tightness. The electrode material uses activated carbon having a large surface area. Thanks to this package and the self-developed internal structure and packaging technology, it is not only small and thin, but also improves liquid leakage resistance and moisture resistance. Backup power for mobile phones, etc.
