12065C473M4T2A

The AVX 12065C473M4T2A is a multilayer ceramic capacitor (MLCC) designed for general-purpose decoupling, filtering, and energy storage applications in electronic circuits. This component belongs to AVX's established line of surface-mount capacitors and is built using advanced ceramic dielectric technology to deliver reliable performance across a wide range of industrial and commercial applications. MLCCs like this part are fundamental building blocks in modern electronics, found on nearly every printed circuit board requiring energy storage or signal conditioning. They serve critical functions including power supply decoupling near integrated circuits, noise filtering in analog and digital circuits, coupling and bypassing in amplifier stages, and general energy storage in timing and switching applications. Engineers specify multilayer ceramic capacitors for these roles because of their compact size, low cost, high volumetric efficiency, and excellent frequency response characteristics. The 12065 in the part number indicates this capacitor uses a 1206 case size in metric dimensions (approximately 3.2mm × 1.6mm), making it a standard mid-size surface-mount component. This package size offers an ideal balance between board space efficiency and ease of handling during automated assembly. The 1206 format is one of the most widely used capacitor packages in industrial electronics, ensuring compatibility with standard PCB design practices and manufacturing processes. The "C" designation in AVX's naming scheme typically indicates a ceramic dielectric composition optimized for stable performance across temperature and frequency ranges common in industrial equipment. The "473" coding represents the capacitance value in picofarad units. The "M" tolerance specification and "4T2A" performance grade indicate this part meets specific reliability and performance criteria suitable for demanding applications where consistent behavior is required. AVX capacitors in this family are engineered to withstand the thermal cycling, vibration, and environmental stresses encountered in industrial control systems, telecommunications equipment, automotive electronics, and renewable energy applications. The ceramic dielectric construction provides inherent resistance to mechanical shock and maintains stable electrical characteristics even when subjected to typical factory and field-use conditions. Engineers typically select this specific part number when their circuit design calls for a capacitor in the 1206 package with the particular capacitance value and performance grade specified. Alternatives might include different case sizes or different dielectric materials, but this part's combination of package, capacitance, and AVX's manufacturing consistency make it a reliable choice for production designs requiring repeatability and long-term availability.
