C1812X334J3JACTU

U2J is an extremely stable dielectric material for Class I multilayer ceramic capacitors (MLCCs). Ceramic capacitors using the U2J dielectric retain over 99% of nominal capacitance at full rated voltage. When referenced to ambient temperature, U2J ceramic capacitors provide a predictable and linear change in capacitance. Additionally, U2J ceramic capacitors extend the available capacitance of Class I MLCCs into a range previously only available to Class II dielectric materials such as X5R and X7R. 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.
