CAP 4700PF 50V 5% U2J 0603
KEMET’s 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. 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. U2J is not sensitive to DC Bias as compared to Class II dielectric materials and retains over 99% of nominal capacitance at full rated voltage. Capacitance change is limited to −750 ± 120 ppm /°C from −55°C to +125°C. These devices are Lead-free, RoHS and REACH compliant without exception and are capable of withstanding multiple passes through a Lead-free solder reflow profile.
