08055C391K4T2A

The AVX 08055C391K4T2A is a surface-mount multilayer ceramic capacitor (MLCC) designed for general-purpose filtering, decoupling, and energy storage applications in electronic circuits. This component belongs to the 0805 package family, one of the most widely used capacitor form factors in modern electronics due to its compact footprint and reliable performance across diverse industrial and commercial applications. Multilayer ceramic capacitors like this model are fundamental building blocks in power supply circuits, signal conditioning stages, and high-frequency applications. Engineers specify MLCCs in decoupling roles to suppress voltage transients and provide local charge storage near active components, in filtering applications to attenuate noise across signal paths, and in timing circuits where stable capacitance is required. The ceramic dielectric material offers excellent volumetric efficiency, allowing substantial capacitance in a minimal physical space, which is critical in densely populated PCB layouts where board real estate is at a premium. The 0805 package format—measuring approximately 2.0mm by 1.25mm—represents an optimal balance between handling convenience for automated assembly equipment and component density. This size is ideal for applications ranging from consumer electronics to industrial control systems, telecommunications infrastructure, and automotive electronics. The standardized dimensions ensure compatibility with standard pick-and-place machinery and reflow soldering processes used in high-volume manufacturing environments. AVX, a well-established manufacturer in the passive components sector, produces MLCCs across multiple dielectric classes and performance grades. Their 0805 capacitors are engineered to meet stringent reliability requirements and are commonly found in applications demanding consistent performance across temperature variations and extended operational lifecycles. Engineers often select AVX components when design specifications call for proven thermal stability, low equivalent series resistance (ESR), and predictable aging characteristics. When evaluating this specific part number against alternatives, engineers should consider their exact application requirements including voltage rating, capacitance value, temperature coefficient characteristics, and frequency response needs. The 0805 form factor provides design flexibility for retrofit applications and legacy system repairs where space constraints and existing board layouts dictate component size requirements. Its widespread adoption also means excellent availability and established supply chain maturity across global distribution networks. This capacitor is suitable for use in both military-grade and industrial-grade applications, depending on the specific dielectric formulation and manufacturing screening level. It integrates seamlessly into modern surface-mount assembly processes and offers the reliability expected from established passive component manufacturers serving the electronics industry.
