08055A1R0CAT4A

The AVX 08055A1R0CAT4A is a thin-film chip resistor designed for precision applications requiring tight tolerance and stability across operating conditions. This component belongs to the 0805 package family, one of the most widely adopted surface-mount resistor sizes in modern electronics manufacturing. The 0805 form factor measures 2.0 by 1.25 millimeters, making it suitable for compact designs while remaining large enough for reliable soldering and rework in production environments. Thin-film resistor technology, which characterizes this component, is manufactured through vacuum deposition processes that create highly uniform resistive films on ceramic substrates. This manufacturing approach delivers superior performance compared to thick-film alternatives, particularly in applications demanding stable resistance values over time and temperature variation. The thin-film construction enables tighter initial tolerances and lower temperature coefficients, making these resistors ideal for precision measurement circuits, instrumentation, and analog signal conditioning applications. This particular part is engineered for general-purpose industrial and commercial applications where reliable resistive performance is essential but extreme operating specifications are not required. Engineers typically specify thin-film 0805 resistors in measurement equipment, data acquisition systems, sensor interfaces, audio circuits, and precision amplifier networks. The compact size allows designers to achieve higher component density on PCBs while maintaining the resistor's performance characteristics, which is particularly valuable in space-constrained applications like portable instrumentation and edge computing devices. The 0805 package standard ensures broad compatibility with automated assembly equipment and standard PCB design tools. This widespread adoption means manufacturers maintain consistent quality standards, and procurement remains straightforward across supply chains. For engineers selecting between resistor technologies, thin-film components like this one offer meaningful advantages over thick-film resistors when circuit performance depends on low noise, stable resistance values, and minimal drift. Conversely, when cost is the primary driver and tolerance requirements are moderate, thick-film alternatives may be more economical. Typical applications include impedance matching networks, filter circuits, biasing networks in amplifiers, transimpedance amplifier input networks, and precision voltage dividers. The component's reliable performance in these roles makes it a standard choice across industrial control systems, laboratory equipment, and professional-grade electronic devices. Designers often stock this part number as a core component in their standard component library due to its proven reliability and consistent availability across manufacturing cycles.
