Solid state capacitor is called solid aluminum electrolytic capacitor. The biggest difference between liquid aluminum electrolytic capacitor and ordinary capacitor is that it uses different dielectric materials. The dielectric material of liquid aluminum capacitor is electrolyte, while the dielectric material of solid capacitor is conductive polymer.

Aluminum electrolytic capacitor is made of aluminum cylinder as negative electrode, which is filled with liquid electrolyte and inserted with a piece of bent aluminum strip as positive electrode. It also needs to be treated by DC voltage to form a layer of oxide film on the positive plate as the medium. It is characterized by large capacity, but large leakage, poor stability, positive and negative polarity, suitable for power filter or low frequency circuit. When using, do not connect the positive and negative poles reversely.

SMD: it is the abbreviation of surface mounted devices, which means surface mount devices. It is a kind of SMT (surface mount technology) components. In the primary stage of electronic circuit board production, through hole assembly is completely completed by hand. After the introduction of the first batch of automatic machines, they can place some simple pin components, but complex components still need to be manually placed before reflow soldering. Surface mounted components mainly include rectangular chip components, cylindrical chip components, composite chip components and special-shaped chip components.
