1206AC331KAT1A

# Product Description The 1206AC331KAT1A is a multilayer ceramic capacitor manufactured by AVX, one of the established producers of passive electronic components. This part belongs to the 1206 package family, which is one of the most widely used surface-mount component sizes in modern electronics manufacturing. The 1206 package designation refers to metric dimensions of 3.2mm by 1.6mm, making it suitable for applications where a balance between component density and ease of assembly is required. Ceramic capacitors like this are fundamental passive components found in virtually every type of electronic equipment. They serve essential functions including power supply filtering, signal coupling and decoupling, noise suppression, and timing circuit stabilization. The multilayer ceramic construction provides stable capacitance performance across a broad range of operating conditions, making these components reliable workhorses in both consumer and industrial electronics. The 1206 package size sits in the mid-range of standard surface-mount capacitor options—larger than 0805 components but smaller than 1210 packages. This sizing makes 1206 capacitors popular in applications where board space is constrained but handling and assembly require reasonable component dimensions. Manufacturers often prefer this size for general-purpose filtering and coupling applications in power management circuits, audio amplifiers, data acquisition systems, and communication equipment. AVX produces 1206 ceramic capacitors across various dielectric materials and performance grades to address different circuit requirements. Depending on the specific dielectric type, these capacitors can be optimized for temperature stability, high-frequency performance, or high-capacitance density. This flexibility allows designers to select the most appropriate variant for their specific application without unnecessarily over-specifying components. Engineers typically choose specific ceramic capacitor part numbers based on several factors: the required capacitance value, voltage rating, temperature stability characteristics (dielectric class), frequency response needs, and physical constraints. The 1206 package has become an industry standard, ensuring broad availability and established manufacturing processes that contribute to consistent quality and reasonable cost. This component would be specified in applications ranging from industrial control systems and power conversion equipment to consumer appliances and telecommunications infrastructure. Its widespread use in the industry means that designers, manufacturers, and maintenance technicians are familiar with its characteristics and performance expectations, reducing design complexity and support requirements.
