08055A121KAT4A

The AVX 08055A121KAT4A is a thin-film chip capacitor designed for precision applications requiring stable capacitance over temperature and time. This component belongs to AVX's established line of surface-mount capacitors in the 0805 package format, a standard footprint widely adopted across industrial electronics, telecommunications, aerospace, and medical device manufacturing. Thin-film capacitors excel in applications where capacitance stability and low dielectric absorption are critical. Unlike ceramic capacitors, which can exhibit significant capacitance drift with temperature and applied voltage, thin-film technology delivers predictable performance across operating conditions. This makes them particularly valuable in analog signal processing, precision measurement circuits, timing networks, and filtering applications where component consistency directly impacts system accuracy. The 0805 case size represents a balance between compact board integration and ease of handling in both automated assembly and manual rework scenarios. This package is small enough for high-density layouts yet large enough to support robust solder connections and reasonable lead spacing for standard manufacturing processes. The form factor has become ubiquitous in modern PCB design, ensuring compatibility with virtually all contemporary pick-and-place equipment and reflow processes. AVX thin-film capacitors in this series are typically specified in applications demanding tight tolerance control, low ESR characteristics, and minimal performance variation across industrial temperature ranges. Engineers often select these components over standard ceramic alternatives when designing precision filters, decoupling networks in sensitive analog circuits, sample-and-hold circuits, and timing reference applications. The technology also performs well in high-reliability environments where component drift could compromise system function or introduce unwanted signal distortion. The part number designation indicates this is a capacitor within AVX's established product matrix, with the alphanumeric suffix encoding specific electrical characteristics and performance ratings. Designers choosing this exact part number are typically matching a proven design specification or addressing performance requirements that necessitate thin-film construction rather than accepting the inherent characteristics of commodity ceramic alternatives. Industrial buyers and design engineers value this component for repeatability and long-term availability. AVX maintains stable manufacturing processes for this type of component, making it suitable for production runs, military and aerospace contracts, and applications requiring documented component traceability and consistent performance verification across manufacturing lots. The 08055A121KAT4A represents a mature, well-established technology option for engineers who have determined that thin-film capacitor performance characteristics are necessary for their application requirements.
