1812SC222MAT1A

The 1812SC222MAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the industry's established producers of passive electronic components. This part number designates a capacitor in the 1812 surface-mount package size, which is a relatively compact form factor favored in modern electronics where board space efficiency matters. Multilayer ceramic capacitors like this one are foundational passive components used across virtually every category of electronic equipment. They serve critical functions in filtering, decoupling, signal coupling, and energy storage applications. The ceramic dielectric material allows for high capacitance density in a small footprint, making MLCCs the default choice for mainstream industrial and consumer electronics manufacturing. The "222" designation in this part number indicates the capacitance value within AVX's numbering system. Capacitors of this general value range are commonly deployed in power supply circuits, digital signal processing stages, RF applications, and general-purpose filtering networks where mid-range capacitance values are required. The 1812 package size—measuring approximately 4.5mm by 3.2mm—represents a middle ground in the MLCC landscape, offering a balance between capacitance per unit volume and ease of handling during automated assembly. AVX's SC series represents their mainstream offering in multilayer ceramic capacitors, designed for reliable performance across commercial and industrial applications. These capacitors are engineered to meet established industry standards for temperature stability, voltage rating, and mechanical robustness. The "T" designation in the part number typically indicates a specific dielectric formulation chosen for particular electrical performance characteristics. Engineers specify this exact part when they need a capacitor that combines proven reliability with cost-effectiveness in high-volume production. The 1812 package size is widely supported by pick-and-place equipment and layout design tools, reducing manufacturing complexity. AVX components are commonly selected in applications where supply chain continuity and consistent quality are important considerations, particularly in industrial control systems, power electronics, telecommunications infrastructure, and automotive electronics. When evaluating alternatives, design engineers typically compare against competing MLCCs in the same package and capacitance class, weighing factors such as voltage rating, temperature stability classification, ESR characteristics, and the manufacturer's reputation for consistent performance. The widespread adoption of AVX capacitors across industrial applications means that design resources and application notes are readily available, supporting both initial design work and long-term support.
