12101C563KAT4A

The AVX 12101C563KAT4A is a multilayer ceramic capacitor (MLCC) from AVX's established component portfolio, designed to serve demanding industrial and commercial electronics applications. This surface-mount component represents a fundamental building block in modern circuit design, functioning as an energy storage and filtering element across power distribution, signal conditioning, and decoupling applications. Multilayer ceramic capacitors like this part are essential in virtually every category of electronic equipment. They appear in power supplies, where they filter ripple and stabilize voltage rails; in audio and RF circuits, where they couple and bypass signals; and in industrial control systems, where reliability under varied operating conditions is critical. The component's construction using multiple layers of ceramic dielectric material and internal electrodes enables compact form factors while delivering the capacitance values required in space-constrained designs. The 12101C563KAT4A designation follows industry standard part numbering conventions, with the "563" segment indicating the specific capacitance value within this series. AVX's construction methods and material selections for this component ensure stable performance across the temperature ranges and voltage stresses typical in industrial environments. The surface-mount package format allows for automated assembly on modern PCBs, reducing manufacturing costs and improving production throughput compared to through-hole alternatives. Engineers select this particular part number based on several practical considerations. The specific capacitance value makes it suitable for particular circuit requirements where standard values from competing manufacturers may not provide an exact match. AVX's quality systems and long manufacturing history provide confidence in consistent performance and long-term availability, important factors in industrial equipment with extended product lifecycles. The component's proven track record across numerous applications reduces design risk compared to less-established alternatives. The multilayer construction inherent to this capacitor technology offers advantages over single-layer designs, including better voltage distribution across layers and improved electrical characteristics. This architecture helps minimize the ESR (equivalent series resistance) and ESL (equivalent series inductance) effects that become problematic at higher frequencies or in sensitive circuits. For engineers evaluating capacitor options in new designs or refresh cycles, this AVX part represents a well-documented choice with established sourcing channels and proven field reliability. Whether used in original equipment manufacturing or in maintenance and repair of industrial systems, the 12101C563KAT4A provides the functional density and performance characteristics expected from a major manufacturer's standard offering in the MLCC category.
