12105A123JAT2A

The AVX 12105A123JAT2A is a tantalum capacitor, a precision passive component widely used in industrial electronics, telecommunications, aerospace, and medical device applications. Tantalum capacitors are valued for their high capacitance density, reliability, and stable performance across demanding operating conditions, making them a preferred choice when space constraints and performance consistency are critical. Tantalum capacitors like this AVX component function as energy storage and filtering elements in electronic circuits. They are commonly deployed in power supply filtering, signal conditioning, decoupling applications, and timing circuits where stable capacitance and low leakage current are essential. The compact form factor of tantalum technology allows engineers to achieve high capacitance values in minimal board space, which is particularly valuable in densely populated circuit designs. The AVX 12105A123JAT2A belongs to AVX's established family of surface-mount tantalum capacitors. The part number structure indicates a standard package configuration appropriate for automated assembly and high-volume production environments. This component is designed for soldering onto printed circuit boards using standard surface-mount technology (SMT) processes, supporting both wave and reflow soldering methods commonly used in industrial manufacturing. Tantalum capacitors are specified in applications where engineers require predictable performance over extended temperature ranges, low equivalent series resistance (ESR), and excellent frequency response characteristics. They exhibit minimal capacitance drift over time and temperature compared to many alternative technologies, which is why they remain the standard in military, aerospace, and medical electronics despite the availability of newer capacitor chemistries. Engineers typically select specific AVX tantalum part numbers based on exact voltage ratings, capacitance values, package sizes, and reliability requirements for their application. The 12105A123JAT2A represents a particular configuration within AVX's product line, suited for applications requiring specific electrical and mechanical specifications. Common reasons for specifying this exact part include qualification in military or aerospace programs, compatibility with existing board designs, temperature stability requirements, or specialized performance characteristics needed for the application. The component's construction uses tantalum metal as the dielectric material, which provides superior performance characteristics compared to ceramic or film alternatives in certain demanding applications. Reliability and consistent performance make these capacitors suitable for mission-critical systems where component failure has high consequences. For engineers evaluating this component, consideration should include circuit voltage requirements, the operating temperature environment, frequency characteristics needed, and whether the specific package and capacitance value align with circuit board layout constraints and electrical specifications.
