William Mak, Kemet senior application engineer from KAIC lab demonstrates how four different capacitor types Aluminum, Aluminum polymer, Tantalum polymer and Ceramics affect the ripple voltage on a boost or buck regulator. Each technology of capacitors is compared using the KAIC-RCE-001 board, which uses the same output capacitance bank at the output of a switching regulator....

KEMET KONNEKT™ package allows two to four ceramic capacitors to be stacked vertically or horizontally while retaining the integrity of the part. It uses transient liquid phase sintering (TLPS) technology to bond component terminations together. The KONNEKT™ U2J capacitors can be used in both orientations, thus minimizing the component footprint, while maximizing the bulk capacitance of a stacked MLCC with design flexibility in mind.
