Product News September 27, 2017

 NICHICON CORPORATION has expanded its ratings for the UCH series of chip-type aluminum electrolytic capacitors which are ideal for automotive applications.
 This series is able to meet the demand for products that meet the harsh environment found in the automotive applications.
 It also meets the need for products with longer life and optimal high- and low-temperature ESR ratings. The UCH series of chip-type aluminum electrolytic capacitors is the industry’s best products rated at 125°C guaranteed for 2,000-hours life Low ESR. 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

 Demand is increasing for space in automotive interior for many different modules. Chip-type aluminum electrolytic capacitors are used in electronic control units (ECUs) that are utilized in engine applications and other drive system modules. These products require a longer life the capability of operating in severe environments, withstanding both high and low temperatures and must have low ESR characteristics.
 By expanding the ratings of this series, we are responding to demand for products that can meet these new demands. At the same time, we expect to contribute to the electricity savings and longer life of equipment.


 Based on the technologies the Company has cultivated to date, this product employs a new low-evaporation, low-resistance electrolyte and high-magnification anode foil. As a result, the UCH series achieves even higher performance than the current UCZ series of 125°C low-temperature ESR-rated chip products, realizing the industry’s highest level of capacitance and lowest ESR. By developing this series, the Company is responding to the demand for products for equipment in on-board applications, as well as the demand for electricity savings and longer life. The product is guaranteed for 2,000 hours at 125°C (endurance-tested ESR at minus 40°C/400kHz φ6.3 x 7.7L: 6Ω, φ8 x 10L: 4.5Ω, φ10 x 10L: 3.5Ω).
