Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs)

U2J Dielectric, 10 – 50 VDC

(Commercial & Automotive Grade)

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.

Benefits

• AEC–Q200 automotive qualified

• Up to 10x increase in capacitance versus C0G

• Extremely low effective series resistance (ESR)

• Extremely low effective series inductance (ESL)

• High ripple current capability

• Low noise solution similar to C0G

• Retains over 99% of nominal capacitance at full rated voltage

• Small predictable and linear capacitance change with respect

to temperature

• Operating temperature range of −55°C to +125°C

• Capacitance up to 470 nF

• DC voltage ratings up to 50 V
