NICHICON CORPORATION expands its product line with the addition of φ12.5 to φ18 mm size capacitors to the UCM Series of high-capacity, high-ripple current chip-type aluminum electrolytic capacitors meeting demands for miniaturization and high-performance in automotive-related and telecommunications equipment.
These products will be displayed at CEATEC JAPAN 2018, held at Makuhari Messe from Tuesday, October 16, to Friday, October 19.
Overview and Development Background
Amid advances in automotive-related and telecommunications equipment electronic component surface mounting, there is a rising demand for chip-type aluminum electrolytic capacitors. In addition to demands for high-capacity capacitors as automotive-related equipment power supply backups, small, high-capacity and high-ripple current capacitors are also required for high-density mounting of telecommunications equipment.
In response to these needs, NICHICON is enhancing its lineup in the UCM Series product line of chip-type aluminum electrolytic capacitors.
Features
Based on technologies NICHICON has accumulated until now, these expanded products realize up to approximately 1.9 times higher capacity and approximately 2.1 times higher ripple current than the same size of existing 105 °C chip products in the UCD Series by applying high-capacitance electrolytic foil and thin electrolytic paper and optimizing the combination of components and structure used. Endurance is guaranteed to 5,000 hours at 105 °C. The introduction of this product will contribute to equipment space-saving and an even higher level of performance.
