KEMET U2J AEC-Q200 MLCCs are surface-mount capacitors featuring a maximum operating temperature of +125°C and are considered stable. The Electronics Industries Alliance (EIA) characterizes the U2J dielectric as a Class I material. The 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. KEMET U2J AEC-Q200 MLCCs feature a highly stable dielectric material that exhibits a negligible shift in capacitance concerning voltage. These capacitors also offer a predictable and linear change in capacitance regarding ambient temperature with no aging effect. The U2J capacitors operate at a DC voltage rating of up to 100V and retain over 99% of nominal capacitance at full rated voltage.

KEMET U2J AEC-Q200 capacitors meet AEC–Q200 qualification requirements. Typical applications include pulse circuits, power conversion, wireless charging, and decoupling.
