1206AC182KAT1A

The 1206AC182KAT1A is a multilayer ceramic capacitor manufactured by AVX, one of the leading suppliers of passive electronic components for industrial and commercial applications. This component belongs to the 1206 package family, a widely standardized surface-mount form factor that measures 3.2 mm by 1.6 mm, making it suitable for high-density PCB layouts where space efficiency is critical. Multilayer ceramic capacitors in the 1206 package are workhorse components found throughout modern electronics, from consumer devices to industrial control systems. The "AC" designation in the part number indicates this capacitor is designed for general-purpose applications with X7R or similar temperature-stable dielectric material, which provides predictable performance across standard operating temperature ranges. The "182" in the part number represents the capacitance value in picofarad notation common to industry coding standards. Engineers typically specify 1206 ceramic capacitors for decoupling, filtering, and signal coupling applications. These components excel in power supply bypassing near integrated circuits, where they suppress high-frequency noise and voltage transients. They are also commonly used in timing circuits, RF applications, and as part of EMI/RFI filtering networks. The 1206 size offers an excellent balance between capacitance density and ease of manufacturing, making it cost-effective for both prototype and high-volume production runs. AVX's 1206 ceramic capacitor series is known for consistent quality and reliability in demanding industrial environments. The multilayer construction provides stable capacitance performance and low equivalent series resistance (ESR), which is particularly valuable in switching power supplies and fast-transient applications. The standardized package ensures broad compatibility with modern pick-and-place assembly equipment and standard PCB footprints. An engineer might select the 1206AC182KAT1A specifically when seeking a proven, readily available component with established manufacturing processes and proven field reliability. The 1206 package size sits at an optimal point in the component spectrum—larger than 0603 packages (offering better current handling and temperature stability) but smaller than 1210 packages (allowing denser layouts). For applications requiring X7R-class temperature stability without exotic materials or specialized performance characteristics, this part represents a practical, cost-effective choice with excellent long-term availability from multiple authorized distributors.
