The two ways of applications are different: tantalum electrolytic capacitors can be used for coupling, filter vibration bypass circuit and other electronic circuits work in the periodic field, while ceramic capacitors are mostly used in high-frequency circuits. Tantalum electrolytic capacitor and ceramic capacitor are mainly different. Under the same capacity environment the volume of tantalum electrolytic capacitor is relatively small and its equivalent series resistance is lower than ordinary electrolytic capacitor. But because tantalum electrolytic capacitor is the key raw material tantalum is very expensive in the market so tantalum capacitor is also very expensive usually used in advanced products ordinary household appliances ceramic capacitor regardless of the price or use more appropriate.
The capacity of ceramic capacitor is usually not too large, and tantalum electrolytic capacitor can be achieved, but there are more de-coupling. Ceramic capacitor is a relatively affordable capacitor, especially the ceramic capacitor of the flat plug-in is the cheapest, and many conventional household appliances can be used. In recent years, with the continuous upgrading of technology, the capacity of ceramic capacitors has become larger and larger. Besides the ceramic capacitors of 4UF, ceramic capacitors are gradually becoming the mainstream instead of tantalum electrolytic capacitors.
