08055A471FAT2A

The AVX 08055A471FAT2A is a thin-film capacitor designed for applications requiring high precision, stability, and reliability in compact form factors. This component belongs to AVX's established family of surface-mount capacitors engineered for demanding industrial and professional electronics applications where performance consistency is critical. Thin-film capacitors are constructed using vacuum-deposited metallic layers on a polymer film substrate, a technology that delivers superior electrical characteristics compared to conventional ceramic alternatives in many application contexts. The 0805 package designation indicates a surface-mount form factor measuring 2.0mm by 1.25mm, making it suitable for high-density circuit board layouts common in modern industrial control systems, measurement equipment, and telecommunications infrastructure. This component class is particularly valued in precision analog circuits, signal conditioning networks, and power supply filtering applications where capacitance tolerance and temperature stability are essential design parameters. Engineers frequently specify thin-film capacitors when circuit performance depends on predictable behavior across operating temperature ranges or when AC ripple handling and low ESR characteristics are required. The film-based construction inherently provides excellent frequency response and low distortion characteristics, making these capacitors suitable for audio signal paths, RF coupling applications, and precision timing circuits. The AVX product line emphasizes consistent performance and long-term reliability, which explains why design engineers in aerospace, medical device manufacturing, industrial instrumentation, and military electronics specifications frequently reference AVX thin-film components. These capacitors maintain stable capacitance values across their operational lifespan and resist performance degradation from repeated thermal cycling—a critical consideration in equipment subjected to wide temperature fluctuations or extended mission profiles. Key reasons an engineer might specify this exact part include the established reputation of AVX manufacturing quality, the well-documented performance history of this capacitor family in existing field deployments, and compatibility with existing design documentation and procurement specifications. For engineers redesigning legacy systems or qualifying replacements in certified equipment, using an established manufacturer's part from a known production lineage reduces qualification risk and documentation burden compared to sourcing from alternative suppliers. The compact 0805 package combined with thin-film technology makes this component particularly relevant for space-constrained applications requiring both small physical footprint and superior electrical performance. This balance of size and capability positions it as a practical choice for modern industrial electronics where board real estate remains limited but performance requirements remain high.
