1206AC392KAT1A

The 1206AC392KAT1A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, a leading producer of electronic components for industrial and commercial applications. This component belongs to the 1206 package family, one of the most widely used surface-mount capacitor formats in modern electronics manufacturing. Multilayer ceramic capacitors are fundamental passive components found in virtually every electronic circuit board produced today. The 1206AC392K designation indicates this is a general-purpose ceramic capacitor designed for applications requiring moderate capacitance values with standard performance characteristics. These capacitors function as energy storage elements, noise filters, coupling and decoupling devices, and signal conditioning components across diverse industrial, consumer, medical, and telecommunications equipment. The 1206 package size represents a balance between physical footprint and handling capability for automated assembly processes. This particular format measures 3.2 mm by 1.6 mm with a standard thickness, making it suitable for high-density circuit board layouts while remaining compatible with standard pick-and-place manufacturing equipment. The "AC" designation within the part number indicates this capacitor uses a standard dielectric material composition typical of general-purpose applications, as opposed to specialized high-temperature or high-voltage variants. Engineers and procurement specialists commonly specify AVX multilayer ceramic capacitors in this package category for decoupling applications near integrated circuits, power supply filtering, EMI suppression, and timing circuit stabilization. The 1206 format offers several advantages over smaller packages like 0805 or 0603 when higher current handling capability or improved thermal performance is required, while remaining more cost-effective than larger packages for applications that don't demand extreme capacitance values. The AVX brand reputation for reliability and consistent manufacturing quality makes this part particularly common in industrial control systems, automotive electronics, power conversion equipment, and telecommunications infrastructure where component consistency and long-term availability are critical factors in design decisions. Designers select this specific part number when their circuit requirements align with its electrical characteristics and when standardization on proven, widely-stocked components reduces supply chain risk. The 1206 package provides excellent compatibility with modern surface-mount assembly processes and offers superior performance compared to older through-hole capacitor technologies for compact, high-reliability applications.
