12065A301FAT2A

The 12065A301FAT2A is a surface-mount ceramic capacitor manufactured by AVX, one of the established leaders in passive component design and production. This component belongs to the 1206 package family, which refers to its physical dimensions of approximately 3.2mm by 1.6mm. This standardized package size makes it compatible with modern automated assembly equipment and PCB layouts commonly found in industrial and commercial electronics. As a ceramic capacitor, this component functions as an energy storage and filtering device within electronic circuits. Ceramic capacitors like this are designed to store electrical charge temporarily and release it as needed, making them essential for applications requiring capacitive coupling, decoupling, bypass filtering, and noise suppression. The 1206 package format represents a mid-range size in surface-mount technology, offering a practical balance between board space efficiency and handling characteristics during manufacturing. The AVX 1206 series is widely recognized in industrial applications where reliability and performance consistency are critical requirements. These capacitors are commonly specified in power supply circuits, signal conditioning stages, timing circuits, and electromagnetic interference (EMI) filtering networks. Engineers frequently encounter them in industrial control systems, automotive electronics, telecommunications infrastructure, medical device boards, and consumer electronics requiring mid-range capacitance values. Ceramic capacitors in this package family are particularly valued for their low cost relative to performance, excellent frequency characteristics, and minimal size footprint. They provide stable performance across typical operating temperature ranges and are inherently robust against mechanical stress from thermal cycling—an important consideration in industrial environments subject to temperature fluctuations. An engineer would specify the 12065A301FAT2A specifically when the exact capacitance value, voltage rating, and tolerance requirements match the circuit design needs. Ceramic capacitors offer different dielectric materials (such as X7R, Y5V, and C0G) that provide different performance characteristics regarding temperature stability and voltage coefficient. The specific part number indicates a particular combination of these attributes, making it the correct choice when substitution with other capacitors could compromise circuit performance or reliability. The 1206 package also provides practical advantages during board assembly, troubleshooting, and field repair compared to smaller packages, while occupying less board space than larger through-hole alternatives. This makes it a standard choice for professional-grade industrial equipment where serviceability and long-term availability are considerations.
