18122A392JAT2A

The 18122A392JAT2A is a capacitor manufactured by AVX, a recognized producer of passive electronic components for industrial, commercial, and defense applications. Based on the part number structure and AVX's product portfolio, this component belongs to the tantalum capacitor family, which are widely specified for applications demanding high reliability and stable performance across challenging operating conditions. Tantalum capacitors are valued in industrial electronics for their volumetric efficiency, meaning engineers can achieve higher capacitance values in smaller physical footprints compared to ceramic or film alternatives. This characteristic makes them particularly useful in space-constrained applications such as power supply circuits, telecommunications equipment, automotive electronics, and military/aerospace systems where component density and reliability are critical. The AVX designation suggests this part is likely configured with a surface-mount or lead-based form factor typical of modern industrial component design. Tantalum capacitors from AVX are generally specified for applications requiring stable capacitance over temperature, low equivalent series resistance (ESR), and predictable electrical behavior under load. These properties make them suitable for filtering, energy storage, timing circuits, and coupling applications in complex electronic assemblies. Engineers often select tantalum capacitors over alternatives when the application requires a combination of high capacitance density, proven long-term reliability in field conditions, and consistent performance across temperature variations. They are particularly common in legacy industrial systems and in new designs where component longevity and failure rate predictability are contractual or safety requirements. Tantalum technology has an established track record in mission-critical applications, and many engineering teams maintain institutional familiarity with the component's behavior and qualification requirements. The specific part number 18122A392JAT2A represents a particular capacitance value, voltage rating, and physical package within AVX's tantalum capacitor lineup. This precision in part numbering is important because tantalum capacitors are not interchangeable across different electrical ratings or package types; the exact part number ensures the component meets the voltage, capacitance, and physical requirements of the intended circuit. Tantalum capacitors do require attention to application conditions, including voltage derating in certain circuit topologies and protection against reverse polarity where applicable, depending on the specific design. These considerations make proper part selection and circuit design collaboration between component suppliers and engineering teams essential for optimal performance and system reliability.
