What is a Solid capacitor?

A solid capacitor is a type of capacitor that uses solid materials as the electrolyte, as opposed to liquid electrolytes in traditional capacitors. Solid-state electrolytic capacitors, such as solid aluminum electrolytic capacitors, are known for their high performance, long lifespan, and enhanced stability. Compared to conventional liquid-based electrolytic capacitors, solid capacitors are less prone to leakage, swelling, and overheating, ensuring safer and more reliable operation. They are characterized by low ESR (Equivalent Series Resistance), making them suitable for power supplies and high-frequency electronic devices. Additionally, solid capacitors are compact and provide high capacitance for their size, which is why they are commonly used in applications such as mobile phones, computer motherboards, and power circuits.

Application of Solid capacitor

１．Mobile phones: Compact solid capacitors are used to provide space-efficient designs.
２．Computer motherboards: They are used in critical circuits due to their high reliability and long lifespan.
３．Power circuits: Solid capacitors are used for stable power supply thanks to their low ESR characteristics.
