Nippon Chemi-Con Developed Ceramic Varistors F Series with Smaller Size and Higher Current
Nippon Chemi-Con has newly developed the F Series, a downsized and higher current version of the existing disc-type Ceramic Varistors V Series.
In recent years, power supply boards for general-purpose home appliances and inverter boards for industrial equipment are becoming smaller. These products contain many of our ceramic varistors and Nippon Chemi-Con has been receiving requests for downsized products while maintaining surge performance.
To meet these demands, Nippon Chemi-Con achieved downsizing of the V Series through optimization of the element composition and internal structure. The F Series has a maximum of approximately 30% higher surge current compared to same-size products of the existing Series. Comparing products with the same surge performance, the mounting surface area of substrates can be reduced by up to 22%.
