08055A681FAT4A

# 08055A681FAT4A Product Description The 08055A681FAT4A is a thin-film chip capacitor manufactured by AVX, a leading supplier of passive electronic components. This component belongs to the 0805 package family, one of the most widely used surface-mount sizes in modern electronics. The 0805 designation refers to the physical dimensions in hundredths of an inch, making this a compact yet easy-to-handle component for both automated assembly and rework applications. As a thin-film capacitor, this part is engineered for applications requiring tight tolerances, low dielectric absorption, and excellent frequency stability. Thin-film technology involves depositing a precise layer of dielectric material onto a ceramic or film substrate, allowing manufacturers to achieve exceptional consistency and reliability compared to conventional thick-film alternatives. This construction method makes thin-film capacitors particularly suitable for demanding analog circuits, precision instrumentation, and high-frequency applications where performance predictability is critical. The 08055A681FAT4A is commonly specified in coupling and decoupling circuits, analog signal conditioning stages, filtering networks, and precision timing applications. Engineers frequently select thin-film capacitors for audio processing equipment, medical diagnostic devices, telecommunications infrastructure, aerospace instrumentation, and industrial control systems where component stability over temperature and time directly impacts system performance. Key reasons an engineer might specify this exact part include its proven reliability in high-reliability sectors, the established manufacturing consistency of AVX's production processes, and the compatibility of the 0805 package with standard pick-and-place assembly equipment. The thin-film construction provides superior performance characteristics in piezoelectric noise reduction, distortion minimization, and frequency response flatness compared to standard ceramic alternatives. Additionally, the 0805 package offers a practical balance between component density and handling ease, making it suitable for both prototype development and high-volume manufacturing. The AVX 08055A681FAT4A fits within a broad product ecosystem, allowing engineers to source related capacitors in identical packaging for design consistency and supply chain simplification. Its established presence in the market means good historical performance data, readily available documentation, and predictable manufacturing availability. For applications where capacitor performance characteristics directly affect circuit function—such as precision filters, timing references, or analog front-end stages—thin-film technology represents a deliberate engineering choice over cost-optimized alternatives, reflecting the component's positioning in the quality and performance segment of the passive components market.
