GEM Introduces KC-LINK Capacitors for Fast Switching Wide Bandgap Semiconductor Applications

Monday, March 12, 2018

Kemet Electronics (KEMET), the world's leading supplier of electronic components, today announced the launch of KC-LINK surface mount capacitors at the 2018 Applied Power Electronics Conference (APC 2018) in San Antonio, Texas. KC-LINK is designed to meet the industry's growing demand for fast switching wide band gap (WBG) semiconductor devices. Wide bandgap semiconductor devices enable the power converter to operate at higher voltages, temperatures, and frequencies, resulting in higher efficiency and power density.

KC-LINK capacitors can operate at very high ripple currents due to their extremely high capacitance and temperature stability, which makes them ideal for DC bus, snubber and resonator applications. The above characteristics benefit from the reliable and patented C0G/NPO metal-to-metal (BME) dielectric system of Gemitech, which has a very low equivalent series resistance (ESR) and thermal resistance during operation. Due to operating temperatures up to 150°C, these capacitors can be mounted near fast-switching semiconductor devices in high power density applications that require minimal cooling.

“KC-LINK capacitors have excellent ripple current capability due to their very low ESR,” said John Bultitude, Vice President and Technical Fellow of GE Healthcare. “Combining its thermal stability and mechanical reliability, KC-LINK is very Suitable for assembly near hot, wide bandgap semiconductor devices where it is difficult to actively cool the device."

Thanks to its high mechanical reliability, KC-LINK capacitors can be installed without the use of a lead frame. This achieves a very low equivalent series inductance (ESL), increases the operating frequency range, and enables further miniaturization. The series offers both commercial and automotive grades, as well as standard, flexible termination systems, and is compliant with lead-free, RoHS, and REACH standards.
