Gallium Nitride semiconductors allow designers to operate at higher frequencies and voltages than their silicon counterparts, enabling power management systems that are smaller and more efficient. These new designs also require capacitors that can operate at these higher frequencies and provide stable performance at the voltages that GaN devices typically operate at.

Tantalum polymer capacitors are expanding their market share in the defence and aerospace market because they offer superior electrical performance (primarily much lower ESR), have outstanding reliability, and display a more benign failure response than the incumbent MnO2-cathode tantalum capacitor technology.

Decoupling and filtering are two of the most common uses of capacitors. It can be tempting to use the two terms interchangeably but in doing so, some of the key elements of usage can be overlooked.

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.

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.
