Product News October 2, 2017

 NICHICON CORPORATION has developed the UCQ series of chip-type aluminum electrolytic capacitors for audio applications. These capacitors contribute to some of the best audio quality in the industry and are ideal for use in high-end audio equipment. The product will be on display at CEATEC JAPAN 2017, taking place at Makuhari Messe from Tuesday to Friday, October 3 to 6.

Overview/Development Background

 The demand continues to increase for higher sound quality in car audio and audiovisual equipment as high-resolution audio improves. With this demand for higher quality end products the demand for components that meet these demands increases. Higher mounting densities are prompting a shift from lead-type to chip-type aluminum electrolytic capacitors, making it essential to offer chip-type aluminum electrolytic capacitors that achieve high audio quality.
 By offering this new series lineup, NICHICON is responding to the need for surface mount high quality products.


 This product achieves higher sound quality than the current UUQ series of aluminum electrolytic capacitors for 105C audio. To realize sound quality that is ideal for car audio, the series employs a new type of specialized electrolytic paper for audio. To achieve ideal sound quality, we have selected the base material carefully, adjusted the density and thickness of the electrolytic paper, and performed repeated listening evaluations. This capacitor offers superb audio resolution, reducing the amount of stress a listener might experience. Using this series should contribute to equipment featuring high sound quality. The product is guaranteed for 2,000 hours at 105℃ (1,000 hours at 105℃ for some sizes).
