KEMET KONNEKT™ U2J Capacitors for Power Applications

KEMET KONNEKT™ U2J surface-mount capacitors are designed for high-efficiency and high-density power applications. KONNEKT utilizes an innovative Transient Liquid Phase Sintering (TLPS) material, creating a leadless multi-chip solution. When combined with KEMET's ultrastable U2J dielectric, KONNEKT enables a low-loss, low-inductance package capable of handling extremely high ripple currents in the hundreds of KHz. U2J capacitors are built with extremely stable Class I dielectric material that exhibits a negligible shift in capacitance with respect to voltage and a predictable and linear change in capacitance with reference to ambient temperature, with a minimal aging effect. The capacitance change is limited to -750±120ppm/°C from -55°C to +125°C. KEMET U2J KONNEKT can be mounted in a low-loss orientation to further increase its power handling capability. The low-loss orientation lowers ESR and ESL, increasing ripple current handling capability. These capacitors are designed for high-efficiency and high-density power applications.
