0805YA120JAT2A

The 0805YA120JAT2A is a fixed film capacitor manufactured by AVX in the popular 0805 surface-mount package format. This component is designed for general-purpose filtering, decoupling, and signal coupling applications across a broad range of industrial and commercial electronics. The 0805 package designation refers to the physical dimensions of the component (0.080 × 0.050 inches), making it one of the most widely used chip capacitor sizes in modern circuit design. This compact footprint allows for high-density PCB layouts while remaining large enough to provide reliable soldering and mechanical stability on automated assembly lines. The surface-mount design eliminates the need for through-hole drilling, reducing manufacturing complexity and cost in high-volume production environments. AVX's 0805YA series represents a mature, cost-effective capacitor family well-suited for applications where performance requirements are moderate and space is limited. These capacitors are commonly found in power supply circuits, where they smooth ripple voltage and maintain stable DC rails. They are equally at home in signal-path applications such as AC coupling, bypassing high-frequency noise, and filtering in audio and communication circuits. The compact size makes them ideal for retrofit and space-constrained designs where larger capacitor formats cannot be accommodated. Engineers typically specify components from this series when designing consumer electronics, industrial control systems, telecommunications equipment, and automotive modules. The combination of reliable performance, proven manufacturing processes, and established supply chains makes this family a low-risk choice for cost-sensitive designs that do not require exotic material properties or extreme operating conditions. The part number suffix "YA" denotes a specific dielectric material composition within AVX's product taxonomy, while the "120J" portion indicates the nominal capacitance value and tolerance class. This particular variant is engineered to meet the needs of engineers seeking dependable capacitor performance in mainstream applications without paying a premium for specialized high-temperature, high-voltage, or low-ESR variants. Standard 0805 capacitors like this component are stocked widely across the electronics supply chain, making them readily available for prototype development, pilot production runs, and full-scale manufacturing. Their ubiquity also means that design engineers can generally find compatible replacement options from multiple manufacturers if supply constraints ever arise, reducing single-source risk in long-term production programs.
