12065A561KAT2A

The AVX 12065A561KAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose filtering, decoupling, and signal coupling applications in electronic equipment. This component belongs to AVX's established MLCC product family, which serves a broad range of industrial, consumer, and telecommunications applications where reliable energy storage and signal conditioning are essential. Multilayer ceramic capacitors like this model are constructed from multiple layers of ceramic dielectric material interleaved with metal electrodes, then stacked and fired into a single monolithic structure. This manufacturing approach enables a compact form factor while delivering consistent electrical performance across temperature and frequency ranges. The 12065 designation refers to the component's physical dimensions in metric format, making it suitable for both through-hole and surface-mount assembly depending on the specific terminal configuration. This part is commonly found in power supply circuits, where it filters voltage ripple and stabilizes DC rails by providing low-impedance charge storage near semiconductor devices. It is also used in signal path applications where AC coupling or bypass functionality is required. Engineers frequently specify MLCC components in automotive electronics, industrial control systems, test and measurement equipment, and consumer electronics where space constraints and cost efficiency are important design considerations. AVX MLCCs are known for stable performance across operating temperature ranges and good frequency response characteristics, making them suitable for both DC blocking and high-frequency signal applications. The specific construction and materials used in this series provide predictable behavior in circuits operating under varying load conditions, which is critical for maintaining signal integrity and power delivery stability in complex systems. When comparing alternatives, engineers often choose this exact part based on its proven reliability, established supply chain presence, and compatibility with existing PCB layouts and assembly processes. The standardized 12065 package size allows straightforward substitution within a given voltage and capacitance rating if needed, while maintaining dimensional compatibility with circuit board traces and component placement tooling. This capacitor is particularly valuable in designs where miniaturization must be balanced against performance demands, and where the cumulative use of multiple small-value MLCCs provides superior filtering compared to single larger capacitors. Its integration into modern electronic systems reflects the industry standard approach to distributed energy storage and signal conditioning in compact form factors.
