The new CeraLink offers many benefits in the stabilization and filtering of DC link circuits of power converters – especially compared to conventional capacitor technologies: thanks to a low ESL value of less than 4 nH as well as a low ESR of less than 4 mΩ, the new capacitors are ideally suited for applications with high switching frequencies and rapid rise times. This includes converters for industrial and automotive electronics that operate with new fast-switching MOSFETS or IGBTs.
CeraLink can be produced with several commonly available terminal configurations, including low profile, SMD, solder pin and press-fit busbar types. Designs that can be integrated in semiconductor power modules are also possible. CeraLink is designed for temperatures between -40 and +125 °C (also up to +150 °C for short periods): thus making it suitable for SiC-based power modules as well. Compared to conventional MLCCs, CeraLink features a positive DC bias. Another benefit of the new capacitor is the very compact dimensions. Depending on the type, they range between 6.84 x 7.85 x 2.65 mm³ and 52.5 x 30.5 x 10.5 mm³.
