1812GA471KAT1A

The 1812GA471KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for use in a wide range of electronic applications where reliable energy storage and signal coupling are required. This component belongs to the 1812 package family, which refers to its surface-mount form factor with dimensions of 0.18 inches by 0.12 inches, making it suitable for compact circuit board designs while maintaining reasonable capacitance values and voltage ratings. Multilayer ceramic capacitors like this model are fundamental passive components used across consumer electronics, telecommunications, automotive systems, industrial control circuits, and power conversion applications. They function as decoupling elements near integrated circuits to suppress voltage transients, serve as coupling and blocking capacitors in signal paths, and participate in timing and filtering networks. The 1812 case size represents a popular mid-range option that balances component density with performance characteristics, offering engineers more flexibility than smaller 0603 or 0805 packages when higher capacitance values or voltage ratings are needed without resorting to larger, space-consuming formats. AVX is a recognized manufacturer of ceramic capacitor solutions, and their multilayer designs typically offer stable performance across commercial and industrial temperature ranges. The GA designation in this part number indicates it belongs to AVX's general-purpose MLCC lineup, making it suitable for applications where specialized high-temperature, high-frequency, or ultra-low-ESR characteristics are not mandatory requirements. This positions the component as a cost-effective choice for mainstream circuit designs. Engineers select specific MLCC part numbers based on several critical factors beyond just capacitance value. These include voltage rating requirements, temperature stability characteristics, equivalent series resistance (ESR), and dissipation factor performance. The 1812 package size allows designers to achieve capacitance values in the picofarad to microfarad range, depending on the dielectric material used and the number of internal layers. The surface-mount configuration enables automated assembly and high-volume production efficiency. This capacitor would typically be specified in applications requiring dependable performance across standard operating conditions without the need for premium characteristics like ultra-low leakage current or exceptional frequency response. It represents a practical choice for mainstream industrial and consumer electronics where reliability and cost-effectiveness are balanced priorities. Circuit designers often stock this type of component as a standard decoupling solution across multiple product lines, simplifying inventory management and procurement processes while maintaining consistent performance across designs.
