SMD capacitor are one of the most common passive components, common type, made of porcelain. Single appearance, single appearance, no silk screen on the surface, no polarity. There are many colors, mainly brown, gray, lavender, etc. There are various sizes. The basic unit of ordinary SMD capacitor: pF.
SMD tantalum capacitor: The price is much more expensive than SMD capacitor, and the material is tantalum dielectric. There is a silk screen on the surface with polarity. There are many colors, mainly black, yellow, etc. There is a white silk screen on the surface of the tantalum capacitor to indicate the positive electrode of the tantalum capacitor, and the capacitance value and working voltage are marked on the silk screen. Most manufacturers also add some tracking marks on the silk screen. There are various sizes, the basic unit of smd tantalum capacitor: μF.
