U2J Dielectric High-Voltage MLCC Capacitors

KEMET's surface-mount capacitors are designed to meet the growing demand for high-AC current-resonant applications

Image of KEMET's U2J Dielectric High-Voltage CapacitorsKEMET's (a YAGEO company) U2J dielectric class I surface-mount multilayer ceramic capacitors (MLCCs) are constructed of a robust and proprietary U2J base metal electrode (BME) dielectric system that offers industry-leading performance at high voltage for high-AC current-resonant applications.

By utilizing KEMET’s proprietary U2J dielectric, this series provides designers with a surface-mount solution with extremely low ESR and ESL with very high-AC current capability. This leads to minimal i2R heating losses which means higher-efficiency power conversion.

U2J is not sensitive to capacitance loss with DC bias as compared to Class II dielectric materials, and retains over 99% of nominal capacitance at full-rated voltage. KEMET's 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.
