08055A820FAT4A

The AVX 08055A820FAT4A is a multilayer ceramic capacitor (MLCC) in the 0805 surface-mount package format, making it a compact, versatile component widely used in modern electronics manufacturing. This part number indicates a capacitor from AVX's established 0805 series, which represents one of the most common chip capacitor sizes deployed across industrial, automotive, telecommunications, and consumer electronics applications. Multilayer ceramic capacitors function as energy storage and filtering components in electronic circuits. They are essential for decoupling power supplies, filtering noise, timing circuits, and managing signal integrity in complex assemblies. The 0805 package form factor—measuring approximately 2.0mm by 1.25mm—offers an ideal balance between compact footprint and handling ease, making it suitable for both high-volume automated assembly and specialized industrial applications where space constraints are moderate. The "A" designation in this part number typically indicates the capacitor's voltage and dielectric class specifications within AVX's nomenclature system. AVX manufactures 0805 MLCCs across a range of voltage ratings and dielectric characteristics, from general-purpose X7R formulations suitable for broad temperature operating ranges to specialty high-K dielectrics for applications requiring higher capacitance density. The specific dielectric and voltage rating of this part determine its suitability for particular circuit applications. Engineers often specify the AVX 08055A820FAT4A and similar 0805 MLCCs when designing circuits requiring reliable, cost-effective capacitance in a proven package size. The 0805 format has achieved widespread standardization across the electronics industry, ensuring consistent performance, reliable supply chains, and compatibility with standard manufacturing processes. AVX's reputation for consistent quality and strict process control makes their 0805 series a dependable choice for applications ranging from power management circuits to high-frequency signal conditioning. This component would typically be found in power distribution networks, where it provides local decoupling near integrated circuits; in analog and mixed-signal circuits requiring frequency compensation; and in filtering applications across industrial control systems, medical devices, and embedded computing platforms. The 0805 package allows for dense capacitor arrays when multiple filtering stages are required, a common scenario in modern multi-core processors and high-speed digital systems. Selection of this specific part would be driven by its voltage rating, capacitance value, and dielectric characteristics meeting the design's operating requirements and environmental conditions. The standardized 0805 footprint ensures straightforward PCB layout and assembly planning.
