2220WC472KAT1A

The 2220WC472KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive electronic components. This part belongs to the 2220 package family, which represents a surface-mount form factor measuring 2.2mm by 2.0mm. Capacitors in this size range are among the most widely used discrete passive components in modern electronics, offering a practical balance between capacitance density, ease of assembly, and board-level performance. Multilayer ceramic capacitors like this unit are fundamental building blocks in contemporary electronic design. They function as energy storage elements, signal coupling and decoupling devices, and filtering components across frequency ranges from DC to several gigahertz. The 2220 package size makes this capacitor suitable for applications where space is moderately constrained but where robust performance is required—neither as tiny as 0402 or 0603 packages, nor as large as through-hole or tantalum alternatives. AVX's 2220-package capacitors are commonly specified in industrial control systems, telecommunications equipment, power supply circuits, and consumer electronics. Engineers regularly incorporate these components in bypass and decoupling networks where they suppress high-frequency noise around integrated circuits, in energy storage applications for power delivery, and in signal conditioning circuits. The ceramic dielectric material provides stable performance across operating conditions and decades of proven reliability in field applications. The specific variant encoded in the part number 2220WC472KAT1A indicates particular performance characteristics within AVX's 2220 lineup. The designation reflects choices about dielectric class, voltage rating, capacitance value, and tolerance grade—parameters that engineers must match to their circuit's requirements. Engineers select this exact part when their design calls for the particular combination of specifications this variant provides, whether due to voltage withstand requirements, capacitance value needs, tolerance tightness, or the temperature stability characteristics of its dielectric class. Selecting a specific capacitor variant like this rather than alternatives requires consideration of the application's voltage stress, frequency response demands, temperature cycling environment, and cost constraints. Ceramic capacitors offer advantages over other technologies including compact size, low equivalent series resistance (ESR) in many formulations, high-frequency response capability, and long-term reliability when properly specified for the electrical environment. For engineers designing or maintaining systems requiring multilayer ceramic capacitors in the 2220 package from an established manufacturer, the 2220WC472KAT1A represents a standard industrial component with proven availability and consistent manufacturing quality.
