Ceramic capacitors are leading miniaturization, downsizing and dominating the market share. The right charts are based on sales VALUE, but if we have these charts in sales VOLUME ceramic capacitors would occupy up to 80% of market share of all capacitors made, on the other hand more expensive tantalum capacitors would shrink its share in volume terms.
