12101C103MAT4A

The AVX 12101C103MAT4A is a multilayer ceramic capacitor (MLCC) designed for general-purpose applications across industrial and commercial electronics. This component belongs to the broad family of ceramic capacitors, which are among the most widely used passive components in modern electronic equipment due to their small size, reliability, and cost-effectiveness. Multilayer ceramic capacitors function as energy storage and filtering elements in circuits, blocking DC current while allowing AC signals to pass. They are essential for smoothing power supply voltages, decoupling noise from integrated circuits, and coupling signals between circuit stages. The "12101" designation in this part number indicates a specific physical package size within AVX's naming convention, while the alphanumeric suffix provides additional information about the component's electrical class and construction. The MAT4A designation suggests this capacitor is formulated for temperature-stable performance across typical industrial operating ranges. Capacitors in this family are commonly used in applications requiring moderate voltage ratings and general-purpose filtering, making them suitable for audio equipment, measurement instruments, industrial control systems, power supplies, and consumer electronics. Engineers typically specify AVX MLCCs in this category for applications where space is limited and high volumetric efficiency is needed. The multilayer construction allows manufacturers to achieve useful capacitance values in remarkably compact packages, which is critical in modern miniaturized designs. The ceramic dielectric material provides good frequency response characteristics and stable performance over time. When selecting between competing capacitor options, engineers consider factors including the required voltage rating, capacitance value, temperature stability class, physical dimensions, and reliability requirements. The specific formulation of this AVX part positions it as a reliable choice for circuits where moderate performance demands and cost-sensitive applications align with the characteristics of general-purpose ceramic capacitors. AVX, a major manufacturer with decades of experience in passive components, produces MLCCs to stringent quality standards suitable for industrial environments. Components in this family are typically specified in high-volume production applications where proven reliability and consistent performance across production runs are essential. This capacitor would be selected by design engineers who have determined through circuit analysis that a general-purpose, temperature-stable ceramic capacitor meets their filtering, coupling, or decoupling needs without requiring specialized performance characteristics. It represents a standard, widely-compatible solution in the passive components toolkit.
