Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs) U2J with KONNEKT Technology for High-Efficiency, High-Density Power Applications (Commercial Grade) Lead-free Overview KEMET s U2J with KONNEKT Technology surface voltage and a predictable and linear change in capacitance mount capacitors are designed for high-efficiency and with reference to ambient temperature, with minimal high-density power applications. KONNEKT utilizes aging effect. Capacitance change is limited to 750 120 an innovative Transient Liquid Phase Sintering (TLPS) ppm/C from 55C to +125C. material to create a leadless multi-chip solution. When combined with KEMETs ultra-stable U2J dielectric, U2J with KONNEKT Technology can also be mounted KONNEKT enables a low-loss, low-inductance package in a low-loss orientation to further increasing its power capable of handling extremely high ripple currents in the handling capability. The low-loss orientation lowers ESR hundreds of kilohertz. (Effective Series Resistance) and ESL (Effective Series Inductance) which increases ripple current handling U2J is an extremely stable Class I dielectric material that capability. exhibits a negligible shift in capacitance with respect to Benefits Applications Extremely high-power density and ripple current Wide bandgap (WBG), silicon carbide (SiC) and gallium capability nitride (GaN) systems Extremely low equivalent series resistance (ESR) Data centers Extremely low equivalent series inductance (ESL) LLC resonant converters Operating temperature range of 55C to +125C Switched tank converters Retains over 99% of nominal capacitance at Wireless charging systems full rated voltage Photovoltaic systems Low noise Power converters Surface mountable using standard MLCC reflow profiles Inverters Low-loss orientation option for higher current handling DC link capability Snubber RoHS compliant and Pb-free Standard Low Loss Built Into Tomorrow KEMET Electronics Corporation KEMET Tower One East Broward Boulevard C1097 KONNEKT U2J 8/25/2021 1 Fort Lauderdale, FL 33301 USA 954-766-2800 www.kemet.comSurface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs) U2J with KONNEKT Technology for High-Efficiency, High-Density Power Applications (Commercial Grade) Typical Performance 1 Typical Ripple Current (A ) rms Mounting Typical ESR at Typical ESL Part Type 100 kHz 200 kHz 300 kHz Configuration 25C, 100 kHz at 25C Standard 1.15 m 1.1 nH 12.0 12.0 11.5 1812 940 nF Low Loss 0.77 m 0.45 nH 18.0 18.0 16.0 Standard 1.3 m 1.6 nH 11.0 10.0 10.0 1812 1.4 uF Low Loss 0.35 m 0.4 nH 20.0 34.0 31.0 1 Ripple current measurements performed at 85C with a peak capacitor temperature of 95C.
