U2J dielectric surface mount multilayer ceramic chip capacitors (SMD MLCCs) 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. In addition, U2J dielectric extends the available capacitance range of Class I MLCCs to achieve values previously only available using Class II dielectric materials like X7R, X5R, Y5V and Z5U. Applications include wireless charging, resonant LLC converters, power conversion, pulse circuit.
