In order to meet the growing demand for higher capacitance multilayer ceramic capacitors (MLCCs) in a Class I dielectric material, KEMET has developed a surface-mount dielectric platform that offers up to 120% more capacitance than available C0G dielectric. Defined by the Electronics Industry Alliance (EIA) as “U2J,” this dielectric material offers an operating temperature range of -55°C to +125°C with capacitance change limited to -750 ±120 ppm/°C and AEC-Q200 automotive qualification.

U2J parts are well-aligned to the stringent demands of automotive systems. Their superior performance versus other technologies can help designers overcome challenges in circuits requiring low-loss, noise reduction, critical timing, and improved capacitance stability versus commonly used X7R-based parts while offering higher capacitance values than C0G.

U2J capacitors are extremely stable with a linear capacitance change with temperature. This allows design engineers to predict the change in capacitance over the operating temperature range. They also retain over 99% of nominal capacitance at full-rated voltage.

KEMET's U2J dielectric, surface-mount MLCCs are lead free and RoHS / REACH compliant without exception. Unlike some film dielectric devices, these capacitors are capable of withstanding multiple passes through a lead-free solder reflow profile.
