12101C563MAT2A

The 12101C563MAT2A is a ceramic capacitor manufactured by AVX, a leading producer of passive electronic components. This part belongs to the multilayer ceramic capacitor (MLCC) family, which represents one of the most widely used capacitor types in modern electronics due to their compact size, reliability, and cost-effectiveness. Ceramic capacitors are fundamental passive components used to store electrical energy, filter signals, and stabilize voltage in circuits. The MLCC design incorporates multiple layers of ceramic dielectric material with interspersed metal electrodes, enabling high capacitance values in a very small physical footprint. This makes them ideal for space-constrained applications where board real estate is at a premium. The "12101C" designation in this part number indicates the physical case size and series classification within AVX's product line. The "563" portion typically relates to the capacitance value and voltage rating specifications. The "MAT2A" suffix denotes the tape-and-reel packaging format, which is standard for automated assembly processes in high-volume manufacturing environments. This packaging method allows for efficient handling, placement, and soldering during circuit board production. Ceramic capacitors of this type are commonly specified in industrial control systems, power supply circuits, telecommunications equipment, automotive electronics, and consumer devices. They serve critical functions including AC coupling, DC blocking, noise filtering, and signal conditioning across a broad frequency range. Engineers often select MLCCs for applications requiring stable performance over time and across varying temperature conditions. The AVX 12101C series is recognized for consistent quality and reliability in demanding industrial applications. When choosing this specific part number over alternatives, engineers typically consider factors such as the exact capacitance and voltage rating combination it provides, its temperature coefficient characteristics, and its proven performance history in similar circuit designs. The tape-and-reel format particularly appeals to manufacturers running automated assembly lines, as it integrates seamlessly with pick-and-place equipment and standard reflow soldering processes. Ceramic capacitors do exhibit certain trade-offs compared to other capacitor technologies. They may show capacitance variation with applied voltage and temperature, and they have relatively low voltage ratings compared to film or electrolytic capacitors. However, their exceptional size efficiency, cost advantage, and availability in numerous value combinations make them the default choice for most general-purpose filtering and coupling applications in modern electronics. The 12101C563MAT2A represents a standard industrial-grade component suitable for applications where reliability and performance consistency are essential requirements.
