Passive Components Raw Material Supply Chain Review

Passive electronic components are raw-materials intensive. The materials consumed mass production of surface mount passive components usually come in the form of engineered powders and pastes, which make up the largest “variable cost” associated with producing capacitors and resistors.

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.

MLCC Shortages and Why They Might Last Longer than Expected

High capacitance base metal electrode multilayered ceramic chip capacitors (MLCC) has been the focal point of electrostatic capacitor technology for more than 25 years. The stacking of advanced dielectric materials and nickel electrode powders in the finished MLCC creates a component with an extremely high capacitance that extends the product offering well into the higher priced electrolytic range.

Limited Capacity To Stack Ceramic Dielectric Extend MLCC Shortages

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.

Tantalum/NbO to MLCC Class 2 Replacement Guidelines

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.

Supercapacitors Enhance Performance

Supercapacitors are used to support peak power and/or to supply backup power. For peak power applications, the load demands more power than the energy source can provide, but the load only operates periodically or sporadically with a low duty cycle, so the average load power is < the power that the energy source can deliver.
