Preliminary Data Sheet
Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)
U2J Dielectric, 10 - 50 VDC (Commercial Grade)
Overview
KEMET’s U2J dielectric features a maximum operating
of Class I MLCCs to achieve values previously only available
temperatureꢀofꢀ125°Cꢀandꢀisꢀconsideredꢀstable.ꢀTheꢀElectronicsꢀ using Class II dielectric materials like X7R, X5R, Y5V and Z5U.
Industries Alliance (EIA) characterizes U2J dielectric as a Class U2J is not sensitive to DC Bias as compared to Class II
Iꢀmaterial.ꢀComponentsꢀofꢀthisꢀclassificationꢀareꢀtemperatureꢀ
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
dielectric materials and retains over 99% of nominal capacitance
at full rated voltage.
