12105A822KAT2A

The 12105A822KAT2A is a ceramic capacitor manufactured by AVX, a well-established producer of electronic components for industrial and commercial applications. This component belongs to the family of multilayer ceramic capacitors (MLCCs), which are among the most widely used passive components in modern electronics due to their compact size, reliability, and cost-effectiveness. Ceramic capacitors serve the fundamental function of storing and releasing electrical charge, making them essential for filtering, coupling, decoupling, and energy storage applications across virtually every type of electronic circuit. The specific designation within AVX's product range indicates this is a general-purpose ceramic capacitor suitable for a broad spectrum of industrial electronics, consumer devices, and embedded systems. The "12105A" prefix in this part number identifies it within AVX's established product family, while the "822" and "KAT2A" suffixes encode information about the capacitor's capacitance value, voltage rating, tolerance class, and packaging format. These designations follow standard industry conventions that allow engineers to quickly understand the component's electrical classification and physical characteristics without requiring constant datasheet consultation. Ceramic capacitors in this category are typically employed in power supply circuits, where they provide essential filtering and ripple reduction. They are commonly found in DC-DC converters, switching power supplies, audio amplifiers, and RF circuits where stable, predictable capacitance is required. Their multilayer construction provides excellent volumetric efficiency, meaning engineers can achieve significant capacitance values in relatively small physical packages, which is critical in space-constrained applications like industrial control modules, telecommunications equipment, and automotive electronics. The MLCC family is valued for its temperature stability, low equivalent series resistance (ESR), and minimal aging characteristics when properly specified for the intended application. Engineers typically select specific AVX ceramic capacitors based on precise voltage ratings, temperature coefficients, and dielectric classes required by their circuit design. The 12105A822KAT2A would be chosen when these particular electrical characteristics align with circuit requirements better than alternative capacitor options. When specifying this exact part number, engineers benefit from the established reliability record of AVX's manufacturing, consistent performance across production batches, and availability through established distribution channels. For industrial applications requiring component traceability and consistent supply, selecting a specific manufacturer's part number—rather than generic alternatives—provides design security and production continuity. This capacitor represents a dependable solution for engineers designing circuits requiring stable energy storage, filtering, or signal coupling in demanding industrial and commercial environments.
