08055A3R3DAT4A

The AVX 08055A3R3DAT4A is a thin-film chip resistor designed for precision applications requiring reliable performance in compact form factors. This component belongs to the 0805 package family, one of the most widely used surface-mount resistor formats in modern electronics manufacturing. The 0805 designation indicates its physical dimensions of approximately 2.0mm by 1.25mm, making it suitable for high-density circuit boards where space efficiency is critical. Thin-film resistors like this model are manufactured using specialized deposition techniques that create a resistive element on a ceramic substrate, resulting in superior tolerance and temperature coefficient performance compared to thick-film alternatives. This manufacturing method allows for tighter control of resistance values and more stable electrical characteristics across temperature variations, making thin-film resistors the preferred choice for applications where precision matters. The "3R3" designation in the part number indicates a 3.3-ohm resistance value. This moderate resistance level places the component in a range commonly used for current sensing, load balancing, and signal conditioning circuits. Thin-film 0805 resistors at this value find frequent application in power distribution networks, instrumentation circuits, and analog signal processing stages where accurate resistance values directly impact circuit performance. Engineers typically specify this exact part when their designs demand the combination of small footprint, precision tolerance, and stable temperature behavior that thin-film technology delivers. In industrial and professional applications—such as test equipment, data acquisition systems, medical devices, and telecommunications infrastructure—the slightly higher cost of thin-film resistors is justified by improved circuit stability and reduced performance drift over product lifetime. The 0805 package size also offers practical advantages for manufacturing and rework. It remains large enough for manual handling and visual inspection if needed, while being small enough to support automated assembly processes and high-density layouts. This balance has made the 0805 format ubiquitous across diverse industries from consumer electronics to demanding industrial control applications. For designers working on circuits where resistance accuracy, temperature stability, and long-term reliability are specified requirements, the AVX thin-film 0805 resistor series provides consistent performance. Whether used in precision measurement circuits, power conditioning stages, or protective load-sharing networks, this component type has proven reliability in both laboratory prototypes and high-volume production environments.
