12105D105MAT2A

The 12105D105MAT2A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, a recognized producer of passive electronic components for industrial and commercial applications. This component belongs to the broader family of surface-mount ceramic capacitors commonly used across electronics manufacturing, aerospace, medical devices, telecommunications, and automotive industries. Multilayer ceramic capacitors are fundamental building blocks in modern circuit design, serving critical functions in filtering, decoupling, coupling, and energy storage applications. The 12105D series from AVX represents a standard package size widely adopted in compact and high-density PCB layouts where space constraints are a primary concern. These capacitors are designed for reliable performance in environments demanding consistent electrical behavior across temperature and frequency ranges typical of industrial equipment. This particular part number indicates a surface-mount device format that offers several practical advantages for manufacturing and design. The compact footprint allows engineers to achieve higher component density on circuit boards while maintaining assembly compatibility with automated pick-and-place manufacturing equipment. The ceramic dielectric material provides stable capacitance characteristics, making it suitable for timing circuits, power supply filtering, signal coupling, and impedance matching applications where predictable performance is essential. AVX multilayer ceramic capacitors in this series are engineered to meet stringent reliability requirements common to industrial applications. Their design typically incorporates multiple internal layers of ceramic material and metal electrodes, which contributes to robust electrical performance and mechanical durability. This construction method provides inherent redundancy, as damage to any single layer does not typically compromise the entire component—a feature valued in mission-critical applications. Engineers often specify this exact part number when existing circuit designs require proven compatibility with established supply chains, when board layout constraints prevent substitution with larger packages, or when the capacitor's established performance history reduces design qualification time. The standardized nature of the 12105D format means that design teams familiar with this part can quickly implement it across multiple product lines without requiring extensive re-qualification or testing protocols. The component's relevance extends to applications requiring long-term availability and consistent manufacturing standards. Industrial buyers, in particular, value parts from established series where replacement and redesign logistics are simplified. This part supports cost-effective maintenance and production planning for manufacturers committed to stable bill-of-materials management across product lifecycles. Whether used in power conversion circuits, signal processing chains, or filtering networks, the 12105D105MAT2A delivers the foundational capacitive function that modern industrial electronics demand.
