The C0402C103J4RACTU is a SMD Multilayer Ceramic Capacitor with C0402C case and 100% pure matte tin-plated finish termination allowing for excellent solderability. The standard capacitor comes with a X7R dielectric. The KEMET's X7R dielectric features a 125°C maximum operating temperature and is considered "temperature stable." The Electronics Components, Assemblies & Materials Association (EIA) characterizes X7R dielectric as a Class II material. The component of this classification is fixed, ceramic dielectric capacitor suited for bypass and decoupling applications or for frequency discriminating circuits where Q and stability of capacitance characteristics are not critical. X7R exhibits a predictable change in capacitance with respect to time and voltage and boasts a minimal change in capacitance with reference to ambient temperature.
