12103D475KAT2A

The AVX 12103D475KAT2A is a capacitor designed for use in industrial and professional electronic applications where reliable energy storage and filtering are required. This component belongs to AVX's established line of multilayer ceramic capacitors (MLCCs), which are among the most widely used passive components in modern electronics manufacturing. Multilayer ceramic capacitors function by storing electrical charge between conductive plates separated by ceramic dielectric material. The "multilayer" construction allows manufacturers to achieve higher capacitance values in compact packages by stacking multiple ceramic layers internally. This design approach has made MLCCs the preferred choice across virtually every industry segment, from consumer electronics to aerospace, telecommunications, automotive, and industrial control systems. The 12103D475KAT2A designation indicates this part uses a 1206 case size, which is a standard surface-mount package measuring approximately 3.2mm × 1.6mm. This intermediate package size offers practical advantages for engineers designing circuit boards—it provides sufficient mechanical robustness for automated assembly and rework while maintaining space efficiency on densely populated boards. The 1206 package remains extremely common in industrial applications where reliability and serviceability are priorities. AVX capacitors in this series are typically specified in circuits requiring stable capacitance across operating temperature ranges, making them suitable for power supply filtering, signal coupling and decoupling, timing circuits, and noise suppression applications. Industrial equipment, test and measurement instruments, power conversion systems, and embedded control modules commonly incorporate components like this one. Engineers often choose AVX multilayer ceramic capacitors based on the manufacturer's reputation for consistent quality, comprehensive availability across distribution channels, and documented long-term reliability in field applications. The specific part number designation (475K) indicates particular electrical characteristics within AVX's product matrix. For applications in demanding industrial environments—including those subject to vibration, temperature fluctuation, or stringent regulatory requirements—selecting a recognized manufacturer's established part number can reduce design risk and simplify supply chain management compared to less-documented alternatives. This capacitor is suitable for through-hole and automated pick-and-place assembly processes commonly used in industrial electronics manufacturing. Its standardized packaging and specifications make it compatible with established design tools and manufacturing workflows.
