12065A181FAT2A

The 12065A181FAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, a leading producer of passive electronic components. This component belongs to the 1206 package family, which refers to its small surface-mount form factor measuring approximately 3.2mm by 1.6mm. This compact size makes it ideal for space-constrained applications where board real estate is at a premium. Multilayer ceramic capacitors are fundamental passive components used in virtually every modern electronic circuit. They function to store and release electrical energy, filter noise, couple and decouple AC signals, and stabilize voltage supplies. The 1206 package size represents a popular mid-range option that balances ease of handling and assembly with reasonable capacitance density, making it suitable for both prototype and high-volume production environments. The "A" designation in this part number typically indicates a standard dielectric type within AVX's product portfolio, generally suitable for general-purpose applications across consumer, industrial, and commercial electronics. These capacitors are commonly found in power supply circuits, signal coupling applications, bypass filtering, and EMI suppression across diverse equipment including telecommunications infrastructure, industrial control systems, automotive electronics, medical devices, and computing hardware. Engineers typically specify AVX MLCCs like the 12065A181FAT2A when they need reliable, cost-effective capacitive solutions with proven field performance and consistent manufacturing quality. AVX's reputation for stringent quality control and consistent production tolerances makes their components attractive for applications where component reliability directly impacts system dependability. The 1206 package specifically offers advantages over smaller packages (0402, 0603) in terms of handling robustness during assembly while remaining significantly more compact than larger packages (1210, 1812), making it a practical choice for mid-range performance requirements. The multilayer ceramic construction provides stable performance across typical industrial operating temperature ranges and offers good frequency characteristics, making these capacitors suitable for both DC bias and AC signal applications. The surface-mount design enables automated assembly using standard pick-and-place equipment, reducing manufacturing costs and improving production efficiency compared to through-hole alternatives. When selecting a specific MLCC like this model, engineers consider the required capacitance value, voltage rating, temperature coefficient, DC bias characteristics, and board layout constraints. The combination of AVX manufacturing reliability, the proven 1206 package form factor, and standard dielectric performance makes this part a straightforward specification for engineers designing or maintaining equipment requiring dependable general-purpose energy storage and filtering capabilities.
