2220HC472KAT1A

The 2220HC472KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, designed for applications requiring reliable energy storage and filtering in compact form factors. This component belongs to the 2220 case size family, which represents a surface-mount package measuring 2.2mm by 2.0mm—a common mid-range footprint that balances capacitance density with practical handling and assembly characteristics. Multilayer ceramic capacitors are fundamental passive components found across nearly every modern electronic device and industrial system. They serve critical functions including power supply decoupling, high-frequency filtering, signal coupling and bypassing, and energy buffering in power conversion circuits. The 2220 package size makes this part particularly suitable for space-constrained applications where engineers need substantial capacitance without resorting to larger packages or alternative technologies like electrolytic or film capacitors. AVX is recognized for manufacturing high-quality ceramic capacitors across diverse product families tailored to different performance requirements. The "HC" designation in this part number indicates this capacitor belongs to AVX's high-capacitance series, meaning it delivers relatively high capacitance values within the 2220 footprint compared to standard or lower-capacitance variants. The "472" code indicates the capacitance value following standard EIA marking conventions. Ceramic capacitors in this category typically operate across broad temperature ranges suitable for industrial environments, though the specific temperature coefficient and stability characteristics depend on the dielectric material formulation. Engineers specify this exact part number when they need the specific combination of package size, capacitance value, and performance class that AVX's HC series provides. Compared to smaller case sizes, the 2220 offers higher capacitance per unit area. Compared to larger packages, it consumes less board real estate and simplifies assembly processes. The choice between ceramic capacitor families often depends on voltage rating requirements, temperature stability needs, and cost targets—factors that make selecting the precise part number critical for circuit optimization. This component is commonly encountered in industrial power supplies, motor drives, telecommunications equipment, automotive electronics, and renewable energy systems. Its small form factor combined with multilayer construction allows designers to achieve dense decoupling networks critical for stable operation of modern microcontrollers, analog circuits, and high-speed digital logic.
