1206AC102KAT1A

The 1206AC102KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, housed in the widely-used 1206 surface mount package. This component belongs to the AC series of ceramic capacitors, which are designed for general-purpose applications across consumer, industrial, and commercial electronics. Multilayer ceramic capacitors like this part are fundamental passive components used to store and release electrical energy in circuits. The 1206 package size offers a practical balance between compact dimensions and ease of handling during automated assembly processes, making it a standard choice in modern PCB designs where space efficiency and manufacturability are both important considerations. The AC series from AVX represents a mainstream product line optimized for cost-effectiveness and reliable performance in non-demanding applications. These capacitors are commonly found in power supply circuits, signal filtering, decoupling applications, and general energy storage functions. The ceramic dielectric material provides stable capacitance across a reasonable range of operating conditions, though engineers should verify specific performance requirements against detailed component specifications. Engineers typically specify the 1206AC102KAT1A in applications where a compact surface mount capacitor is needed without extreme performance demands. The 1206 footprint is particularly valuable because it offers better mechanical strength and solderability compared to smaller packages, while still maintaining the space savings of surface mount technology over through-hole alternatives. This makes it popular in cost-sensitive manufacturing environments where automated pick-and-place assembly is standard. The part designation itself contains manufacturing date codes and traceability information embedded in the suffix, which can be important for inventory management and reliability tracking in production environments. When evaluating alternatives, engineers might consider other package sizes (0805, 0603, or 1210) depending on available PCB real estate, or different dielectric types if higher capacitance density or specialized temperature performance is required. Designers should consult the complete component datasheet to verify electrical characteristics, temperature coefficients, voltage ratings, and reliability specifications for their specific application. The 1206 package's standardized footprint means that many similar capacitors from various manufacturers can be interchangeable, though electrical performance and quality ratings may vary. For applications requiring tighter tolerance control or superior frequency response characteristics, engineers might explore premium capacitor series, but the AC series represents an economical choice for general industrial and commercial circuit designs where standard performance is sufficient.
