12105C823KAT2A

The AVX 12105C823KAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose filtering, decoupling, and signal coupling applications across industrial and commercial electronics. As a component from AVX's established capacitor lineup, this part represents a reliable choice for engineers designing power supply circuits, audio systems, and high-density PCB layouts where compact component footprints are essential. Multilayer ceramic capacitors like this unit are constructed from alternating layers of ceramic dielectric material and metal electrodes, allowing manufacturers to achieve significant capacitance values in small physical packages. The 12105 designation indicates this part uses a 1210 surface-mount package size (metric 3225), which provides a balance between component density and ease of automated assembly. This intermediate package size is popular in applications where space is constrained but not as severely as designs using 0603 or smaller packages. The "C" in the part number typically indicates the capacitor's general performance class, positioning it within AVX's standard-grade offerings rather than high-reliability military specifications or specialized high-frequency variants. This classification makes the part suitable for commercial and industrial equipment where performance and cost-effectiveness are both important considerations. Engineers frequently specify AVX capacitors in this series for power distribution networks where bulk capacitance is needed close to integrated circuits, voltage regulators, or power conversion stages. The ceramic dielectric material provides stable performance across typical industrial operating temperature ranges and maintains consistent capacitance values under normal bias conditions. Additionally, MLCCs offer excellent high-frequency performance characteristics, making them suitable for switching power supplies and digital signal processing applications. The 823 portion of the part number encodes the capacitance value using AVX's standard three-digit nomenclature common across their ceramic capacitor portfolio. This standardized coding system helps engineers quickly identify component values when reviewing schematics or managing inventory. Designers might select this specific part over alternatives when they require the combination of AVX's established quality reputation, the proven reliability of ceramic technology in their application class, proven compatibility with their assembly processes, and the practical advantage of the 1210 package size for their particular layout constraints. The intermediate package size also offers better thermal performance compared to smaller packages while remaining space-efficient relative to larger alternatives.
