08055C473JA79A

The 08055C473JA79A is a multilayer ceramic capacitor (MLCC) manufactured by AVX, one of the leading suppliers of passive components for industrial and commercial electronics. This component belongs to the 0805 package family, a widely used surface-mount form factor that measures 2.0mm × 1.25mm, making it compact enough for densely populated PCBs while remaining practical for hand assembly and rework operations. As a ceramic capacitor, this component is designed to store and discharge electrical charge in circuits requiring stable capacitance values. The specific part number designation indicates this is a general-purpose MLCC suitable for decoupling, filtering, and bypass applications across a broad spectrum of industrial equipment, consumer electronics, and telecommunications infrastructure. AVX's ceramic capacitors are known for reliable performance in demanding environments and are frequently specified in applications where consistent electrical behavior and long-term stability are critical. Multilayer ceramic capacitors like this model are preferred in modern electronics because they offer excellent volumetric efficiency—delivering substantial capacitance in a minimal footprint. This makes them invaluable in space-constrained designs, particularly in industrial control systems, power supplies, signal conditioning circuits, and high-density computing equipment. Engineers often specify MLCCs when they need multiple capacitors performing different roles (bulk filtering, high-frequency decoupling, EMI suppression) without dramatically increasing board area or component count. The 0805 package format specifically strikes a practical balance for manufacturers. It's small enough to enable modern miniaturization but large enough to handle during automated assembly without excessive difficulty. This size is standard across most contract manufacturers and design houses, reducing supply chain complications and design validation risk. Engineers select AVX components for their reputation regarding voltage derating, temperature stability, and resistance to mechanical stress during assembly. The 08055C473JA79A, as part of AVX's established MLCC portfolio, is engineered to withstand standard reflow soldering processes and the thermal cycling common in industrial applications. Its reliability under vibration and thermal stress makes it particularly suited for equipment operating in harsh environments, such as power distribution systems, automotive electronics, and industrial automation controllers. For applications requiring careful impedance control or predictable frequency response, ceramic capacitors remain the preferred choice over film or electrolytic alternatives. Designers working on precision analog circuits, RF filtering stages, or power delivery networks often specify MLCCs because their electrical characteristics remain stable across operating frequency ranges relevant to their designs.
