1210AA821KAT3A

The 1210AA821KAT3A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the industry's established producers of passive electronic components. This part is housed in a 1210 surface-mount package, which is a widely recognized standardized size that measures approximately 3.2mm by 2.5mm, making it suitable for high-density PCB layouts in modern electronics manufacturing. Multilayer ceramic capacitors like this one serve as essential energy storage and filtering elements in virtually every category of electronic equipment. They are particularly valued in industrial, telecommunications, automotive, medical, and consumer electronics applications where reliable performance and compact form factors are required. The 1210 package strikes an effective balance between capacitance density and ease of handling during automated assembly processes, which is why it remains one of the most commonly specified package sizes in professional electronics design. The "821" designation in the part number indicates the capacitance value and multiplier according to standard EIA coding. AVX's component families in this package type typically serve applications requiring stable capacitance across operating temperature ranges, with performance suitable for power supply filtering, signal coupling and decoupling, bypass filtering, and timing circuits. These capacitors are engineered to maintain predictable performance in high-reliability environments where component failure can affect system uptime or safety. Engineers and procurement specialists often select AVX multilayer ceramic capacitors for their consistent quality control, established supply chain presence, and proven track record in demanding applications. The 1210 package size offers practical advantages over smaller alternatives when designers need improved current-handling capability or slightly higher capacitance values without migrating to larger packages. Conversely, it provides more flexibility than larger packages when space constraints require optimization. For applications involving power conditioning, signal integrity, or filtering in industrial control systems, communication equipment, or power electronics, the 1210 package represents a reliable mainstream choice. AVX's manufacturing quality and materials science expertise ensure that components from this family meet stringent reliability standards including extended temperature operation and mechanical robustness during thermal cycling. When specifying passive components for production designs, engineers value suppliers who maintain consistent part availability and quality across manufacturing runs. The 1210AA821KAT3A, as part of an established AVX product family, provides the standardization and predictability that professional designs require, whether for prototype development or high-volume manufacturing programs.
