12105C563KAT4A

The AVX 12105C563KAT4A is a multilayer ceramic capacitor (MLCC) designed for general-purpose energy storage and filtering applications in electronic circuits. As a component from AVX's established capacitor product line, this part is engineered to meet the needs of industrial and commercial equipment manufacturers who require reliable, compact capacitance solutions. Multilayer ceramic capacitors like this unit are fundamental building blocks in modern electronics, found in power supplies, signal conditioning circuits, decoupling networks, and RF applications. Engineers specify MLCCs when they need high volumetric efficiency—delivering significant capacitance in a small physical footprint—combined with excellent frequency response characteristics. The ceramic dielectric material provides stable performance across a range of operating conditions, making these capacitors suitable for both DC blocking and AC coupling roles. The part number designation "12105C563KAT4A" encodes important information about the component's specifications. The initial digits typically indicate the physical case size in the 1210 form factor, which represents a standard rectangular surface-mount package dimension widely recognized across the electronics industry. The "563" designation suggests the capacitance value in this series, while the "K" indicates the tolerance class. This particular variant includes the "T4A" suffix, which denotes specific construction details and performance characteristics relevant to its intended application category. AVX is a well-established manufacturer of capacitive components with a reputation for consistent quality and reliable performance in demanding environments. Their MLCC products are widely used in industrial control systems, telecommunications infrastructure, automotive electronics, and consumer electronics where component reliability directly impacts system performance and longevity. Engineers typically choose this specific part number when they have validated its performance characteristics against their circuit requirements and need the assurance of a consistent, documented component from a recognized manufacturer. The standardized packaging and well-defined electrical properties of MLCCs in this family allow for straightforward integration into manufacturing processes and simplified inventory management. For applications requiring filtering of power supply rails, AC coupling between circuit stages, or energy storage in compact form factors, the AVX 12105C563KAT4A represents a proven solution that balances performance, size, and manufacturing compatibility. Its presence in established supply chains and compatibility with standard PCB assembly processes make it a practical choice for production environments.
