KONNEKT U2J for High-Eciency, High-Density
Power Applications (Commercial Grade)
Overview
KEMET's U2J KONNEKT surface mount capacitors are
designed for high-eciency and high-density power
applications. KONNEKT utilizes an innovative Transient
Liquid Phase Sintering (TLPS) material to create a leadless
multi-chip solution. When combined with KEMET’s ultra-
stable U2J dielectric, KONNEKT enables a low-loss, low-
inductance package capable of handling extremely high
ripple currents in the hundreds of kilohertz.
U2J is an 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 minimal aging
effect. Capacitance change is limited to –750
±120 ppm/°C from –55°C to +125°C.
U2J KONNEKT can also be mounted in a low-loss
orientation to further increasing its power handling
capability. The low-loss orientation lowers ESR (Effective
Series Resistance) and ESL (Effective Series Inductance)
which increases ripple current handling capability.
