12061A471FAT4M

The 12061A471FAT4M is a multilayer ceramic capacitor (MLCC) 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-used surface-mount form factor that balances practical handling and assembly compatibility with reasonable performance for mid-range applications. Multilayer ceramic capacitors like this part are fundamental building blocks in modern electronics, used for energy storage, filtering, decoupling, and signal coupling across virtually every type of electronic system. The "1206" designation refers to the component's physical dimensions (approximately 3.2mm × 1.6mm), making it large enough to handle moderate capacitance and voltage ratings while remaining small enough for compact PCB layouts. This size is particularly popular in industrial control systems, power supplies, telecommunications equipment, and consumer electronics where space efficiency and manufacturing scalability are important. The "F" designation in the part number typically indicates the capacitance value and tolerance class specific to AVX's naming conventions. Engineers often select MLCCs like this 12061A471FAT4M for applications requiring stable performance across operating temperature ranges, relatively low equivalent series resistance (ESR), and cost-effective bulk purchasing for production runs. The ceramic dielectric material provides good frequency response characteristics, making these capacitors suitable for both DC and AC filtering applications. Common industrial applications include decoupling circuits near integrated circuits and processors, where they suppress voltage spikes and supply noise; power distribution networks in industrial control boards and PLCs; and signal conditioning circuits in measurement and sensor systems. The component is also frequently found in LED drivers, motor controllers, and auxiliary power supplies in industrial equipment. When specifying this exact part number, engineers typically prioritize AVX's reputation for consistency and reliability in production, the proven performance of the 1206 package for their particular application, and the specific electrical characteristics (capacitance value, voltage rating, and temperature stability class) that this designation represents. Compared to smaller packages like 0805, the 1206 offers slightly higher capacitance density and better handling during assembly; compared to larger packages like 1210, it provides space savings while maintaining adequate electrical performance for most industrial and commercial applications. This capacitor is suitable for standard lead-free assembly processes and RoHS-compliant manufacturing environments, meeting the environmental standards increasingly required in industrial procurement specifications.
