12103D475MAT2A

The 12103D475MAT2A 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 general family of fixed capacitors designed to store and filter electrical energy in circuit designs across numerous industries. Multilayer ceramic capacitors like this unit are fundamental building blocks in modern electronics, appearing in power supply circuits, signal filtering stages, decoupling applications, and frequency compensation networks. Engineers specify MLCCs in consumer electronics, telecommunications infrastructure, industrial control systems, automotive electronics, and medical devices where reliable energy storage and noise suppression are critical to circuit performance. The part designation indicates this is a surface-mount component, typical of contemporary PCB assembly practices. Surface-mount capacitors offer significant advantages over through-hole alternatives, including reduced board space consumption, improved high-frequency performance due to lower parasitic inductance, and compatibility with automated manufacturing processes. These characteristics make them the standard choice in space-constrained applications and high-volume production environments. AVX's MLCC product lines are engineered for stability across temperature ranges and frequency ranges commonly encountered in industrial settings. The ceramic dielectric material used in these capacitors provides good volumetric efficiency, meaning designers can achieve substantial capacitance values in compact packages. This efficiency is particularly valuable when multiple filtering stages are required or when circuit boards face footprint limitations. Engineers typically choose specific MLCC part numbers based on several interrelated factors: the required capacitance value, voltage rating appropriate to the application, package size constraints imposed by PCB layout, temperature operating range, and acceptable equivalent series resistance (ESR) for the intended circuit function. The 12103D475MAT2A designation encodes information about these electrical and physical parameters within its part number structure. Industrial buyers often select components from established manufacturers like AVX due to the reliability of supply chains, consistency of component quality, and availability of technical documentation that supports design validation and compliance verification. In applications where circuit uptime is critical—such as industrial automation, power distribution, or safety systems—component selection from reputable manufacturers with proven manufacturing standards becomes particularly important. The MLCC category remains one of the most widely used passive component families in electronics manufacturing, and AVX's offerings within this segment reflect decades of development in ceramic materials science and manufacturing process refinement. For engineers designing circuits that require dependable energy storage, noise filtering, or signal conditioning, this component represents a practical solution within the broader ecosystem of passive electronic components.
