08055A390FAT4A

The AVX 08055A390FAT4A is a thin-film chip capacitor designed for applications requiring precision and stability in compact form factors. This component belongs to AVX's established line of surface-mount capacitors engineered for demanding industrial and electronic equipment applications. Thin-film capacitors are fundamental building blocks in modern electronics, used wherever circuit designers need reliable energy storage, filtering, coupling, or timing functions. The 0805 case size indicates this is a standard surface-mount package measuring approximately 2.0mm by 1.25mm, making it suitable for high-density circuit board layouts while remaining accessible for both automated assembly and hand-soldering repair work in field-service scenarios. The "390" designation in the part number refers to the capacitance value, and components in this range are commonly specified in analog signal conditioning circuits, power supply filtering stages, RF applications, and precision measurement instrumentation. AVX thin-film capacitors are recognized across the industry for their stability over temperature and time, making them particularly valuable in applications where circuit performance cannot drift significantly during the product's operational lifetime. Typical use cases for capacitors in this family include coupling and decoupling functions in audio equipment, timing circuits in control systems, bypass filtering near high-speed digital logic, and precision analog filtering in medical and test instrumentation. The thin-film construction provides superior frequency response characteristics compared to conventional ceramic capacitors in many frequency ranges, and the technology generally offers better performance consistency when subjected to thermal cycling or extended operating periods. Engineers often select AVX thin-film capacitors over alternative manufacturers when they need documented reliability histories, consistent manufacturing processes, or when existing designs have been validated against AVX specifications. The brand's reputation in aerospace and defense sectors has established these components as trusted choices for applications where component failure rates must be minimized and predictability is essential. The 08055A390FAT4A specifically appeals to designers working on legacy systems requiring direct replacements, as well as new designs targeting industrial equipment, telecommunications infrastructure, and precision electronic test systems. Its compact footprint allows integration into space-constrained assemblies, while the thin-film technology ensures electrical performance remains stable throughout the component's service life. This component is typically purchased by contract manufacturers, system integrators, and original equipment manufacturers developing products requiring high reliability and consistent performance across production runs and field deployment.
