2225SC223KAT1A

The 2225SC223KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the industry's established suppliers of passive electronic components. This part belongs to the 2225 package family, which uses imperial dimensions of 0.223 inches by 0.223 inches, making it a relatively compact surface-mount component suitable for high-density PCB layouts. Multilayer ceramic capacitors are fundamental building blocks in modern electronic equipment, serving critical roles in filtering, decoupling, signal coupling, and energy storage applications. The 2225 case size represents a mid-range footprint that balances volumetric efficiency with handling and reflow characteristics on automated assembly lines. This package type is widely used in consumer electronics, industrial control systems, telecommunications infrastructure, and automotive applications where space constraints exist but component robustness is required. The "SC" designation in this part number indicates AVX's SuperCap or standard ceramic dielectric family, which typically targets general-purpose applications requiring reliable performance across moderate voltage and temperature ranges. Engineers select components from this family when they need dependable capacitance values without requiring specialized high-temperature, high-voltage, or ultra-low-loss characteristics that premium ceramic or film capacitor alternatives might offer. The trailing characters "223KAT1A" encode specific electrical and packaging parameters, with the "223" portion commonly indicating a capacitance value in the picofarad range according to standard industry coding conventions. The "K" typically denotes tolerance class, while the final characters specify termination type, packaging configuration, and manufacturing date code. Multilayer ceramic capacitors in the 2225 package size excel in applications requiring multiple capacitors in close proximity, such as power supply filtering near integrated circuits, RF bypass networks, and coupling stages in signal conditioning circuits. Their low equivalent series resistance and inductance make them particularly valuable for high-frequency applications and rapid charge-discharge cycles. An engineer might specify the 2225SC223KAT1A over alternative component options when the exact capacitance value, AVX brand reliability, and this specific package footprint match proven design requirements. The 2225 package offers a middle ground between smaller 1206 or 1210 capacitors, which may have thermal or volumetric limitations, and larger 1812 or 2220 packages that consume additional board space. Standardizing on established part numbers like this throughout a product line simplifies procurement, reduces design variability, and leverages manufacturer's proven quality history.
