12065C103KAT2A

The AVX 12065C103KAT2A is a multilayer ceramic capacitor (MLCC) from AVX's established component lineup. This surface-mount capacitor is designed for general-purpose filtering, decoupling, and energy storage applications across a wide range of industrial and commercial electronic equipment. Multilayer ceramic capacitors like this model are among the most widely used passive components in modern electronics. They consist of alternating layers of ceramic dielectric material and metal electrodes, stacked and fired into a compact package. This construction allows manufacturers to achieve significant capacitance values in very small physical sizes, making MLCCs ideal for space-constrained applications where weight and board real estate are concerns. The 12065 designation refers to the component's physical package size, indicating it uses a standard surface-mount footprint. This package type is compatible with automated pick-and-place assembly equipment, making it economical for high-volume production runs. Engineers favor standardized package sizes because they simplify PCB design, reduce tooling costs, and ensure compatibility with established manufacturing processes. AVX capacitors in this family are commonly specified in power supply circuits, where they handle input filtering and output voltage stabilization. They're equally at home in signal coupling and bypass applications, where they block DC while passing AC signals or provide a low-impedance path to ground for high-frequency noise. Industrial control systems, telecommunications infrastructure, automotive electronics, and consumer device power management all routinely incorporate similar components. The "C" designation in the part number indicates this is a general-purpose MLCC, typically suitable for applications where performance requirements are moderate and cost-effectiveness is important. These capacitors offer solid reliability across standard operating temperature ranges and are proven through decades of use in demanding industrial environments. When selecting a specific capacitor for a design, engineers must balance capacitance value, voltage rating, temperature coefficient, ESR characteristics, and physical size constraints. This particular part number represents one specific combination of these parameters within AVX's comprehensive capacitor portfolio. Designers often specify exact part numbers like this one based on detailed circuit analysis, ensuring the capacitor will perform reliably throughout the product's lifetime while meeting cost and availability targets. For applications requiring high reliability, low loss, or specialized performance characteristics, alternative parts within the MLCC family may be more appropriate. Likewise, for less demanding applications, lower-cost options might be considered. The choice of this specific part number typically reflects a careful engineering assessment of the application's particular requirements.
