Nichicon Corporation is expanding its – UBY Series of aluminum electrolytic capacitors with 63 to 100 V-rated voltage products. These products will be displayed at CEATEC JAPAN 2016, held October 4 (Tuesday) to 7 (Friday) at MakuhariMesse
Overview/Development Background
The auto industry's recent adoption of electronic controls has called for the placement of ECUs (Engine Control Unit) inside the cabin or near the engine compartment. There are also demands for higher efficiency in order to enhance comfort and protect the environment when it comes to electronic components, this means high temperature, high capacity, high ripple current and high voltage aluminum electrolytic capacitors.
In response to these demands, Nichicon added the increased rated voltage range UBY Series to its product lineup.
Features
With superior high temperature performance, high capacity and a high ripple current rating, the UBY Series is optimized for automotive onboard electronics applications. The voltage rating of these products exceeds the capacity of Nichicon's current UBT Series by up to 1.8 times. This is made possible by the corresponding voltage expansion of our high-capacitance electrolytic foil and internal structure optimization. In addition, the UBY Series features a high ripple current up to 2.2 times that of the UBT Series, the result of high-performance electrolytes that maintain excellent stability even at high temperature ranges. These elements, when combined, will enable further contributions to space-saving, high-efficiency automobile control units.
