SMD ceramic capacitors are made of ceramic materials (BaTiO₃, PbTiO₃, SrTiO₃), etc. The compact surface mount (SMD) package makes them especially suitable for high-density circuit board design, with good stability and durability, suitable for long-term stable operation, commonly used in filter circuits, bypass power supply pins, signal coupling circuits, decoupling circuits, and mainly used in mobile phones, computers and intelligent devices, communication equipment, automotive electronics, and so on. Is an indispensable component in modern electronic technology.
