08055A821FAT4A

The AVX 08055A821FAT4A is a multilayer ceramic capacitor (MLCC) designed for general-purpose filtering, decoupling, and energy storage applications in electronic circuits. As a component in the 0805 surface-mount package family, this capacitor offers a compact form factor suitable for space-constrained board layouts while maintaining reliable performance in demanding industrial and commercial applications. Multilayer ceramic capacitors like this part are fundamental building blocks in modern electronics, commonly found in power supply circuits, signal coupling and decoupling stages, and noise filtering applications across consumer, industrial, and telecommunications equipment. The 0805 package size represents a standard in the industry, balancing ease of automated assembly with sufficient component area for reliable soldering and mechanical stability. The capacitor's construction uses ceramic dielectric material layered with internal electrodes, a proven technology that delivers stable performance across temperature and frequency ranges typical of industrial equipment. This construction method allows manufacturers to achieve high capacitance values in small physical packages, making MLCCs like the 08055A821FAT4A valuable in modern densely-populated circuit boards where space optimization is critical. Engineers typically specify this particular part number when they require a standard, cost-effective capacitor suitable for non-critical filtering applications or where the specific capacitance value and voltage rating match their circuit requirements. The 0805 package remains popular because it offers excellent manufacturability with modern pick-and-place equipment, wide availability from multiple suppliers, and a proven track record of reliability in field applications. This standardization also means design teams can leverage existing footprints and assembly processes rather than qualifying alternative package sizes. The part's suitability for industrial applications stems from ceramic capacitors' inherent robustness and their ability to operate reliably in varying environmental conditions. They resist mechanical shock better than some alternative technologies and maintain predictable electrical behavior across the temperature ranges encountered in factory floor equipment, HVAC systems, instrumentation, and control electronics. When considering alternatives, engineers evaluate factors including the exact capacitance value required, voltage rating specifications, frequency response characteristics, and physical space constraints on the PCB. The 0805 package and AVX's manufacturing reputation make this part an established choice for applications where proven performance and supply chain reliability matter more than pursuing marginal performance improvements. This component is suitable for engineers designing industrial control systems, test equipment, power conversion circuits, and general-purpose electronic assemblies where standard-value capacitors meet the circuit requirements.
