08055A1R0DAT2A

The AVX 08055A1R0DAT2A is a thin-film chip resistor designed for high-reliability applications requiring precision performance in compact form factors. As a component from AVX's established resistor portfolio, this part represents the type of precision resistive element commonly found in measurement equipment, medical devices, telecommunications infrastructure, and industrial control systems where accuracy and stability are critical design parameters. Thin-film resistors are manufactured through a fundamentally different process than conventional thick-film components. Material is deposited in extremely thin layers onto a ceramic substrate, then precisely trimmed to achieve tight tolerances and excellent performance characteristics. This manufacturing approach enables these resistors to deliver superior frequency stability, lower noise, and better temperature coefficient performance compared to standard alternatives. The 0805 package designation indicates this is a surface-mount device in the widely-used 2.0mm × 1.25mm footprint, making it suitable for modern PCB assembly processes and allowing dense component placement. The "1R0" designation in the part number indicates a 1 ohm nominal resistance value, though the complete electrical specifications should be verified against the manufacturer documentation for your specific application requirements. One-ohm resistors serve particular functions in circuit design—they are frequently employed as current-sensing elements in power supplies, motor controllers, and battery management systems where precise measurement of current flow is necessary. They also appear in impedance matching networks, as shunt elements in measurement circuits, and in signal conditioning applications where their low resistance value and precision characteristics provide circuit performance benefits. The "A" suffix typically indicates a specific tolerance or performance grade within AVX's product range. Engineers selecting this particular part number rather than generic alternatives are typically working within specifications that demand consistent, predictable resistor behavior over time and across temperature variations. This is particularly important in precision measurement applications, feedback control loops, and safety-critical systems where component drift could compromise system performance or accuracy. The 0805 package offers several practical advantages for manufacturers: it balances ease of hand-rework with automated assembly efficiency, maintains reasonable thermal characteristics for most industrial applications, and provides sufficient lead spacing for reliable soldering without excessive complexity. For engineers designing next-generation equipment or upgrading legacy systems, specifying precision thin-film resistors in this package provides confidence in long-term reliability and performance consistency while maintaining compatibility with standard manufacturing processes.
