1812CA472JAT1A

The 1812CA472JAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for general-purpose energy storage and filtering applications in electronic circuits. This component belongs to the 1812 package family, a surface-mount form factor that provides a balance between compact size and practical handling for automated assembly in industrial and commercial electronics. Multilayer ceramic capacitors are among the most widely used passive components in modern electronics due to their reliability, small footprint, and cost-effectiveness. The 1812 package designation refers to metric dimensions of 4.5mm by 3.2mm, making it suitable for space-constrained applications while remaining large enough to accommodate moderate capacitance values and voltage ratings without excessive cost or assembly complexity. This particular part number indicates a capacitor from AVX's established ceramic capacitor product line, a manufacturer known for consistent quality in passive components across industrial, automotive, and telecommunications sectors. The ceramic dielectric technology used in these capacitors provides stable performance across typical operating temperature ranges and is well-suited to decoupling, filtering, and general circuit stabilization duties. Engineers typically specify MLCCs in the 1812 package for applications including power supply decoupling near integrated circuits, signal filtering in RF and analog circuits, energy storage in switching power supplies, and noise suppression in digital logic circuits. The relatively large physical size of the 1812 package compared to smaller alternatives like 0603 or 0805 typically allows for higher capacitance values or voltage ratings in a single component, reducing the need for parallel capacitor arrays in some designs. The choice of the 1812 package over smaller alternatives is often driven by specific circuit requirements where a single larger capacitor is preferable to multiple smaller devices for cost, board space efficiency, or performance reasons. Conversely, designers might select this part over larger packages when space is still a consideration but capacitance requirements exceed what smaller packages can reasonably provide. AVX capacitors in this family are recognized for stable performance in industrial environments and compatibility with standard PCB assembly processes. The surface-mount construction allows for automated placement and reflow soldering, making it ideal for high-volume production scenarios common in industrial electronics manufacturing. For applications requiring this specific part number, compatibility with existing board designs, established supply chains, or particular electrical characteristics within AVX's product specifications would typically be the primary drivers of component selection.
