The C1812V334KCRACTU is an ArcShield surface-mount Multilayer Ceramic Chip Capacitor with 100% matte Sn termination, 1812 case and X7R dielectric. The phenomenon of surface arcing is caused by a high voltage gradient between the two termination surfaces or between one of the termination surfaces and the counter internal electrode structure within the ceramic body. It occurs most frequently at application voltages that meet or exceed 300V, in high humidity environments and in chip sizes with minimal bandwidth separation (creepage distance). This phenomenon can either damage surrounding components or lead to a breakdown of the dielectric material, ultimately resulting in a short-circuit condition (catastrophic failure mode). Patented ArcShield technology features KEMET's highly reliable base metal dielectric system combined with an unique internal shield electrode structure that is designed to suppress an arc-over event while increasing available capacitance.
