Although ceramic capacitors still have drawbacks, they are the smallest and most cost-effective solution for many applications, and are therefore found in nearly every type of electronic device today.
Solid tantalum electrolytic capacitors have the highest capacitance per unit volume (CV product). Only double layers or supercapacitors have higher CV products.
In the 1µF range, ceramics are still smaller and have lower ESR than tantalum, but solid-state tantalum capacitors are less affected by temperature, bias voltage, or shock effects. Tantalum is several times more expensive than ceramic capacitors, but in low-noise applications where piezoelectric effects cannot be tolerated, tantalum is often the only viable option.
