2220AA472KAT1A

The 2220AA472KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading producers of passive electronic components for industrial and commercial applications. This component belongs to the 2220 package family, which refers to its physical dimensions in metric notation (22mm x 20mm), making it a relatively large surface-mount capacitor suitable for applications requiring moderate to high capacitance values in a compact footprint. Multilayer ceramic capacitors are fundamental building blocks in modern electronics, used to store electrical energy, filter noise, couple or decouple signals, and stabilize power supplies across a wide range of industrial and consumer equipment. The 2220 package size positions this part as a workhorse component in power management circuits, automotive electronics, telecommunications infrastructure, industrial control systems, and renewable energy applications where space is limited but capacitance requirements are substantial. AVX's 2220 series capacitors are engineered for reliability in demanding industrial environments. These components typically offer excellent frequency response characteristics, making them suitable for both DC and AC applications. The ceramic dielectric material used in MLCCs provides stable performance across temperature ranges commonly encountered in industrial settings, with relatively low equivalent series resistance (ESR) and equivalent series inductance (ESL) compared to older capacitor technologies. Engineers often specify the 2220AA472KAT1A for applications where the combination of package size, capacitance value, and AVX's quality standards align with circuit requirements. The specific designation indicates a particular capacitance value and electrical rating within the series. Designers selecting this exact part number typically do so because the capacitance and voltage rating match their circuit needs precisely, while the 2220 package offers the right balance between component density and ease of assembly on modern PCBs. The ceramic MLCC technology in this part provides advantages over alternatives such as electrolytic or tantalum capacitors, including longer operational life, lower leakage current, better high-frequency performance, and better compatibility with lead-free soldering processes required in contemporary manufacturing. However, ceramic capacitors do exhibit some capacitance variation with applied voltage and temperature, which engineers factor into their design calculations. For applications requiring high reliability, the choice of AVX as the manufacturer provides assurance of consistent quality and adherence to industry standards. This part is suitable for OEM assembly operations, repair and rework applications, and equipment upgrades where component replacement or upgrading is necessary to meet current performance or compliance requirements.
