1206AA680KAT1A

The 1206AA680KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, housed in the industry-standard 1206 SMD (surface mount device) package. This component is designed for general-purpose filtering, decoupling, and energy storage applications across a wide range of electronic equipment. Multilayer ceramic capacitors like this part are among the most widely used passive components in modern electronics. The 1206 package format represents a mid-range size in the SMD capacitor spectrum, offering a practical balance between board space efficiency and handling ease during assembly. This package is well-established in industrial and commercial manufacturing environments and is compatible with standard pick-and-place assembly equipment. The "AA" designation in AVX's part numbering indicates this capacitor belongs to their standard commercial-grade product line, positioned for mainstream industrial and consumer applications rather than specialized or high-reliability segments. Engineers typically specify components from this series when cost-effectiveness and consistent performance are priorities, without requiring military-grade screening or extended temperature ranges. Common applications for 1206 ceramic capacitors include power supply filtering on printed circuit boards, decoupling between integrated circuit power pins, signal coupling and filtering in audio circuits, and general energy storage in timing and sensing circuits. They are found in telecommunications equipment, industrial control systems, automotive electronics, consumer appliances, and computing devices. The 1206 package provides several practical advantages. It offers reasonable capacitance density compared to smaller packages like 0805 or 0603, while remaining small enough for dense PCB layouts. The larger size compared to miniature packages also provides better mechanical robustness and easier manual rework when necessary. AVX's commercial-grade MLCCs in this package format typically demonstrate reliable performance across standard industrial temperature ranges. An engineer might select this specific part number over alternatives based on several factors: the combination of AVX's established reputation and manufacturing consistency, the proven availability and cost structure of commercial-grade 1206 capacitors, compatibility with existing supply chains, and the suitability of the commercial performance class for non-critical filtering and energy storage roles. When specifications require particular voltage ratings, capacitance values, or temperature characteristics beyond the commercial standard, alternative part numbers within AVX's 1206 lineup would be considered instead. The 1206 form factor remains a versatile choice for applications where designers need a cost-effective, readily available passive component with adequate performance margins for typical industrial and commercial electronic systems.
