Nichicon Corporation has developed the VC series featuring the smallest radial leaded type aluminum capacitors in the industry, of miniature size and large capacitance, principally suited to power sources of all kinds, including AC adaptors for mobile devices, guaranteed for 2,000 hours of service at 105°C. The line-up will be on display at the CEATEC JAPAN 2012 exhibition to be held at Makuhari Messe from 2-6 October (Tues-Sat).


Background of Development

The smartphone is a product that has taken off in recent years, and in the past year in Japan, the penetration rate has almost doubled. The increase in usage is forecast to continue. With this expected rapid growth of smartphones, and the constant stream of new products from device manufacturers, cost competition is going to increase. As such, there is a demand for increased miniaturization of aluminum capacitors for the AC adaptors used to recharge smartphones and other similar devices.
To meet these market needs, Nichicon has developed the VC series line-up of radial lead type miniature size aluminum capacitors.


Main Features

The VC series applies the Nichicon capacitor manufacturing technologies such as the adoption of high capacitance, high strength aluminum electrolytic foil and the optimization of electrode design and electrode uptake that have led to around a 20% size reduction over the current VY series and up to double the capacitance. These are the best aluminum capacitors for AC adaptors for mobile devices and other power sources where miniaturization is key.
