12105E224MAT2A

The AVX 12105E224MAT2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose applications across industrial, consumer electronics, and telecommunications equipment. This component belongs to AVX's established family of surface-mount capacitors, commonly specified in filtering, coupling, and decoupling roles within power distribution networks and signal integrity circuits. Multilayer ceramic capacitors are among the most widely used passive components in modern electronics due to their compact size, reliability, and cost-effectiveness. The 12105E224MAT2A is constructed from alternating layers of ceramic dielectric material and metal electrodes, fired together to create a monolithic structure. This architecture enables high capacitance density in a small footprint, making it ideal for space-constrained applications where engineers need to minimize board area without sacrificing performance. The part number nomenclature indicates this capacitor uses a 1210 case size, a standard metric package measuring 12mm × 10mm. This mid-range package size represents a practical balance between component density and ease of handling during manufacturing. The "E" designation in AVX's coding system typically refers to X7R or similar stable dielectric material, which provides relatively flat capacitance performance across temperature and voltage ranges. The "224" code specifies a nominal capacitance value in the 0.22µF range, a popular specification for bulk capacitance and noise filtering applications. Engineers specify this exact part when they require a capacitor with the dimensional compatibility of the 1210 package combined with the proven reliability of AVX's manufacturing processes. The component is well-suited for use near integrated circuits where decoupling is critical, in audio signal paths requiring coupling capacitors, or in power supply circuits needing bulk energy storage. The surface-mount design allows for automated assembly using standard pick-and-place equipment, reducing production costs and improving throughput in high-volume manufacturing environments. Industrial applications frequently employ this component in motor drives, programmable logic controllers, frequency converters, and sensor interfaces where electrical noise rejection and signal integrity are important considerations. The ceramic construction provides excellent frequency response characteristics and negligible ESR in many operating ranges, which is particularly valuable in switching power supply applications where rapid charge and discharge cycles occur. Designers choosing between alternative capacitor types might select this MLCC over film or electrolytic alternatives when space is limited, when environmental stability is required, or when cost per unit needs to remain competitive in large production runs. AVX components are known for consistent quality and long-term availability, making them a dependable choice for designs requiring component longevity and supply chain stability.
