1210AA821JAT3A

The 1210AA821JAT3A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the world's leading suppliers of passive components for industrial and commercial applications. This component belongs to the 1210 package family, which refers to its physical dimensions of 12mm by 10mm, making it suitable for applications requiring moderate capacitance values in a compact footprint. Multilayer ceramic capacitors like this unit are fundamental passive components used extensively across industrial electronics, telecommunications equipment, power supply circuits, and consumer electronics. The 1210 package size positions this capacitor in the mid-range of surface-mount options, offering a balance between capacitance density and ease of assembly on modern PCBs. Components in this family are typically used for decoupling, filtering, and energy storage applications where reliability and cost-effectiveness are priorities. AVX's 1210 series capacitors are recognized for consistent performance across temperature ranges commonly encountered in industrial environments. These components are designed to meet strict quality standards required by manufacturers serving automotive, aerospace, and industrial control markets. The construction using multiple ceramic layers allows for improved performance characteristics compared to single-layer alternatives, particularly in terms of capacitance stability and voltage handling. Engineers typically specify components from the 1210AA family when they require a proven, readily available solution that balances performance with manufacturing efficiency. The standardized package size ensures compatibility with established assembly processes and PCB design practices. AVX's manufacturing reputation provides assurance of consistent performance and long-term availability, which is particularly important for industrial applications with extended product lifecycles. The ceramic material composition and multilayer construction provide excellent stability across frequency ranges typically encountered in industrial electronics, from DC blocking applications to high-frequency filtering. These capacitors are generally suitable for use in non-polarized applications where voltage reversal is possible, distinguishing them from electrolytic alternatives. Typical reasons an engineer might select this specific part number include compatibility with existing designs, proven performance in similar applications, established supply chain relationships, and the need for a ceramic solution where organic alternatives may not meet reliability or environmental requirements. The 1210 package also offers advantages in automated assembly, reducing manufacturing costs while maintaining assembly quality. Whether used in power conditioning circuits, signal coupling applications, or as part of multi-layer filtering networks, the 1210AA821JAT3A represents a standard industrial-grade passive component choice backed by AVX's established quality standards and global distribution network.
