Overview
KEMET 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. KEMET automotive grade
capacitors meet the demanding Automotive Electronics
Council's AEC–Q200 qualification requirements.
Capacitance change is limited to −750 ±120 ppm/°C from
−55°C to +125°C. These devices are lead (Pb)-free, RoHS
and REACH compliant without exception and are capable
of withstanding multiple passes through a lead (Pb)-free
solder reflow profile.
