KEMET C1812V104KDRACTU SMD Multilayer Ceramic Capacitor, ArcShield™, 1812 [4532 Metric], 0.1 �F, 1 kV, � 10%, X7R

The C1812V104KDRACTU is an ArcShield� surface mount multilayer ceramic Chip Capacitor with 100% pure matte Sn-plated termination finish, X7R dielectric and 1812 case. The surface mount capacitor is designed for use in high voltage applications susceptible to surface arcing (arc-over discharge). 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).
