08055A2R2CAT2A

The AVX 08055A2R2CAT2A is a thin-film surface-mount chip resistor designed for precision applications requiring tight tolerance and stable performance across temperature ranges. This component belongs to the 0805 package family, a standard size widely used in modern electronic assemblies where space efficiency and automated manufacturing are priorities. Thin-film resistors like this part are manufactured using specialized deposition and laser-trimming processes that allow them to achieve close tolerance specifications and low temperature coefficients of resistance. These characteristics make them particularly valuable in applications where resistor stability directly impacts circuit accuracy and performance. Common use cases include precision measurement instrumentation, analog signal conditioning, audio equipment, medical devices, and industrial control systems where resistor drift over time or with temperature changes could degrade overall system performance. The "2R2" designation in the part number indicates the resistor value in ohms. The 0805 package format—measuring approximately 2.0 mm by 1.25 mm—represents a practical balance between component density and ease of handling and repair. This size is small enough for compact modern circuit boards yet large enough to be reliably placed by standard pick-and-place equipment and hand-soldered if necessary during prototyping or rework. Engineers typically specify thin-film resistors over thicker-film alternatives when circuit designs require predictable long-term behavior, low noise characteristics, or when resistor tolerances feed directly into system specifications. Applications in precision analog circuits, feedback networks, and sensor interfaces benefit from the superior stability and accuracy that thin-film technology provides. The AVX brand carries strong market recognition among original equipment manufacturers and contract manufacturers for quality and consistency. This component is suitable for lead-free soldering processes standard in modern electronics manufacturing. Its small size and surface-mount design enable efficient board layout and automated assembly, reducing manufacturing costs and assembly time compared to through-hole alternatives. The part integrates readily into mixed-signal designs, RF circuits, and power supply applications where precision biasing or measurement resistors are needed. When selecting between resistor options, engineers weighing this part should consider whether the application genuinely requires thin-film precision characteristics or whether general-purpose thick-film resistors would suffice. For cost-sensitive applications with loose tolerance requirements, thicker-film alternatives may be more economical. However, in measurement-grade circuits, audio signal paths, or systems where resistor performance contributes to calibration or accuracy specifications, the thin-film construction of this AVX component justifies its selection.
