Recently, the demand for smaller and thinner sized portable electronic communication devices, such as mobile and "Smart" phones, has increased significantly. As such, the electronic components used in these products need to be smaller and thinner to facilitate these more compact packages.With that industry demand in mind, Seiko Instruments Inc. (abbr. "SII", President: Masafumi Shimbo, Headquarter: 1-8 Nakase Mihama-ku Chiba-shi Chiba, Tel:+81-43-211-1111) will proudly introduce the world's thinnest and smallest (1*) chip-type electric double layer capacitor, part number CP3225A, in October 2008.The SII Electric Double-Layer Capacitor (EDLC) functions as a rechargeable electrical storage device, and is commonly used for mobile-phone memory and clock back-up during the primary battery's run out or replacement. Somewhat different than the coin cell battery that may often be used in these applications, this new device contains activated carbon, which has large surface area, in its electrode, while using organic solvent in the electrolyte. Current EDLC packages are typically "coin" shaped, and don't completely utilize the board space allocated to them due to the round shape. Also, metal solder tabs are always required for surface ....
