08055A0R5CAT4A

The AVX 08055A0R5CAT4A is a thin-film chip resistor designed for high-precision applications requiring reliable performance in compact electronic assemblies. This component belongs to the 0805 package family, one of the most widely used surface-mount resistor formats in modern electronics manufacturing. The 0805 package designation refers to its physical dimensions, making it suitable for densely populated circuit boards where space is at a premium while maintaining adequate electrical performance and thermal handling capabilities. Thin-film resistors like this model are engineered using precision deposition techniques that enable tighter tolerances and superior stability compared to thick-film alternatives. These characteristics make them particularly valuable in applications where consistent electrical behavior and minimal drift over temperature and time are critical. Engineers typically specify thin-film resistors in measurement circuits, instrumentation, signal conditioning, and precision analog applications where component accuracy directly impacts system performance. The 0805 form factor offers an excellent balance of practical advantages. It's large enough to handle reasonable power dissipation for signal-level applications and can be assembled with standard pick-and-place equipment found in professional manufacturing environments. Simultaneously, it's compact enough to enable high circuit density, which is increasingly important as electronic devices become smaller and more feature-rich. This size is also more robust than smaller packages like 0603 or 0402, reducing potential handling damage during assembly and improving field reliability. AVX is recognized as a established manufacturer of passive components with a reputation for consistent quality and reliable supply chains. Components from major manufacturers like AVX often command specification preference in professional and industrial applications where supply security and performance consistency are important considerations. Engineers might select this specific part number when their design requires a thin-film resistor in the 0805 package with particular electrical characteristics suited to their circuit topology. Common scenarios include precision measurement systems, sensor signal conditioning, industrial control electronics, medical device instrumentation, and telecommunications equipment. The thin-film construction ensures that the resistor will maintain its specified characteristics across temperature variations and extended operating life, reducing the risk of calibration drift or performance degradation in deployed systems. When evaluating alternatives, engineers must consider the trade-offs between package size, tolerance grade, temperature coefficient, frequency response, and manufacturing availability. The 0805 thin-film format from AVX provides a well-established, proven solution that integrates readily into professional manufacturing processes while delivering the precision performance that industrial and instrumentation applications demand.
