12102C103JAT2A

The 12102C103JAT2A is a multilayer ceramic capacitor manufactured by AVX, one of the leading suppliers of passive electronic components. This part belongs to the 1210 package family, which refers to its surface-mount form factor with dimensions of 12.7mm by 10.2mm, making it suitable for applications where moderate component density is required without needing the smallest available packages. As a ceramic capacitor, this component is designed to store and release electrical energy in circuits. The "C" designation and the numeric code in the part number indicate specific electrical characteristics within AVX's product lineup. Multilayer ceramic capacitors like this one are fundamental building blocks in modern electronics, used to filter noise, couple signals, stabilize power supplies, and provide energy storage in a compact, cost-effective package. The 1210 package size represents a middle ground in surface-mount capacitor offerings. It provides greater capacitance capability than smaller packages while remaining practical for automated assembly on standard printed circuit boards. This makes it a popular choice in industrial and consumer applications where engineers need reliable performance without excessive board space consumption. Typical applications for capacitors in this package class include power supply decoupling, signal coupling and blocking, noise filtering in RF circuits, and energy storage in switched-mode power supplies. Industrial equipment, telecommunications infrastructure, automotive electronics, and industrial control systems frequently incorporate components of this type. The specific electrical properties indicated by the part number make this capacitor suitable for particular impedance or frequency response requirements within these applications. Engineers typically specify AVX multilayer ceramic capacitors when they need consistent quality, reliable sourcing, and proven performance in demanding environments. AVX's reputation in the passive components market means that OEM manufacturers and contract electronics assemblers can rely on these parts for high-volume production runs. The 1210 case size strikes a practical balance for designers working within standard manufacturing constraints and cost requirements. The surface-mount design allows for efficient automated placement during PCB assembly, reducing labor costs and improving consistency compared to through-hole alternatives. The multilayer construction provides the capacitance density needed for modern circuit designs while maintaining the stability and reliability expected in industrial applications. When evaluating this part against alternatives, engineers consider the specific capacitance value, voltage rating, and dielectric characteristics encoded in the part number, along with AVX's proven track record in supplying these components to demanding markets where component failure could be costly.
