KEMET U2J dielectric features a maximum operating temperature of 125°C and is considered stable. The Electronics Industries Alliance (EIA) characterizes U2J dielectric as a Class I material. Components of this classification are temperature compensating and are suited for resonant circuit applications or those where Q and stability of capacitance characteristics are required. U2J is an extremely stable dielectric material that exhibits a negligible shift in capacitance with respect to voltage and boasts a predictable and linear change in capacitance with reference to ambient temperature with no aging effect.
