1812GA470KAT1A

The 1812GA470KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for applications requiring reliable energy storage and signal coupling in compact form factors. This component belongs to the 1812 package family, a surface-mount device that measures 1812 in EIA dimensions, making it suitable for high-density PCB layouts where space optimization is critical without sacrificing capacitance value. Multilayer ceramic capacitors like this part are fundamental building blocks in modern electronic circuit design, serving functions including power supply decoupling, filtering, bypassing, and AC coupling across a broad spectrum of industrial and consumer applications. The 1812 package represents a mid-range footprint—larger than 0603 or 0805 packages but smaller than 2220 or larger formats—offering engineers an effective compromise between capacitance density and board real estate. AVX's ceramic capacitor lines are recognized for consistent quality and performance across commercial and industrial temperature ranges. Components in this family are typically specified in applications involving power distribution networks, audio circuits, switching power supplies, telecommunications equipment, automotive electronics, and industrial control systems. The ceramic dielectric material provides stable capacitance across frequency ranges and maintains reliable performance in environments subject to thermal cycling and mechanical stress. Engineers select the 1812GA470KAT1A specifically when design constraints require a capacitor that delivers adequate capacitance in a proven, cost-effective package format. The "GA" designation within AVX's part numbering indicates this capacitor belongs to their general-purpose ceramic line, suitable for standard industrial applications rather than specialized military or high-reliability segments. This positioning makes it particularly valuable for OEM designers and contract manufacturers seeking components that balance performance requirements with procurement efficiency. The surface-mount 1812 package facilitates automated assembly processes, reducing manufacturing costs and improving production throughput compared to through-hole alternatives. This format is fully compatible with standard pick-and-place equipment and reflow soldering processes used in contemporary PCB manufacturing. Designers choosing this part number would typically do so based on schematic requirements calling for a ceramic capacitor in the 1812 package footprint, with capacitance value and voltage rating suited to specific decoupling, filtering, or coupling functions. AVX's established reliability reputation and broad market availability make this component a dependable choice for applications where component longevity and consistent electrical performance are important considerations.
