Surface Mount Multilayer Ceramic Chip Capacitors (SMD MLCCs) KC-LINK for Fast Switching Semiconductor Applications DC Link, Snubber, Resonator Capacitor, 150C (Commercial & Automotive Grade) Overview KEMET s KC-LINK surface mount capacitors are designed KC-LINK C0G dielectric technology also exhibits high to meet the growing demand for fast switching wide mechanical robustness compared to other dielectric bandgap (WBG) semiconductors that operate at higher technologies, allowing the capacitor to be mounted without voltages, temperatures, and frequencies. By utilizing the use of lead frames. This provides extremely low KEMET s robust and proprietary C0G/NPO base metal effective series inductance (ESL) increasing the operating electrode (BME) dielectric system, these capacitors are frequency range allowing for further miniaturization. For well suited for power converters, inverters, snubbers, and added reliability, KC-LINK is now available with flexible resonators, where high efficiency is a primary concern. termination technology that provides superior flex With extremely low effective series resistance (ESR) and performance over standard termination systems, addressing very low thermal resistance, KC-LINK capacitors can the primary failure mode of MLCC s flex cracks. operate at very high ripple currents with no change in capacitance versus DC voltage, and negligible change In addition to commercial grade, automotive grade in capacitance versus temperature. With an operating devices are available and meet the demanding Automotive temperature of 150C, these capacitors can be mounted Electronics Councils AECQ200 qualification requirements. close to fast switching semiconductors in high power density applications, which require minimal cooling.
