Overview

KEMET’s U2J dielectric features a maximum operating

temperatureof125°Candisconsideredstable.TheElectronics

Industries Alliance (EIA) characterizes U2J dielectric as a Class

Imaterial.Componentsofthisclassificationaretemperature

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.
