Tantalum polymer to MLCC Replacement Guidelines

Let’s all get to the same baseline. KO-CAP is KEMET’s tantalum-based polymer electrolytic capacitor. Like any other tantalum capacitor, it is a slug of sintered tantalum powder that has a tantalum pentoxide layer grown on it, with a layer of conductive polymer acting as the cathode. This conductive polymer gives the capacitor much lower ESR than “traditional” tantalum capacitors. That’s all I have to say about that.

Limited capacity expansion in the MLCC industry, specifically the ability to stack ceramic layers (limited capex in three-dimensional stacking capacity for barium titanate dielectric composition and nickel electrode paste) will extend shortages of MLCC to 2020 and beyond.

MLCC capacitor market is currently going through a tough supply time period. MLCC manufacturers are leaving their low margin, high volume, consumer segment and concentrating on supply of higher added value parts. This is resulting in a considerable MLCC shortage that may take several years to be resolved.

Solid and polymer tantalum capacitors vs. SMT MLCCs

There are two primary capacitor technologies that are most often considered for surface-mount applications: electrostatic and electrolytic. The most common electrostatic types are MLCCs and film capacitors. Due to current bottlenecks in the procurement of surface-mount ceramic capacitors, however, designers are looking for substitutes to keep their production lines running smoothly, and to find long term replacements for hard to find ratings.
