12061A2R2CAT2A

The AVX 12061A2R2CAT2A is a thin-film chip resistor designed for precision applications requiring stable performance across demanding operating conditions. This surface-mount component belongs to the 1206 package family, one of the most widely used sizes in modern electronics due to its balance of compact footprint and ease of handling during assembly and rework operations. Thin-film resistors like this part are manufactured using vacuum deposition techniques to apply a resistive material onto a ceramic substrate, then precision-trimmed to achieve tight tolerances. This manufacturing approach delivers superior stability compared to thick-film alternatives, making thin-film resistors the preferred choice when circuit performance depends on resistance values remaining consistent over time and across temperature variations. The "2R2" designation in the part number indicates a 2.2-ohm resistance value, a low-resistance specification commonly found in precision measurement circuits, current-sensing applications, and signal conditioning networks. Engineers specify thin-film resistors in applications where thermal coefficient performance, long-term stability, and noise characteristics directly impact system accuracy. These components are frequently deployed in instrumentation, data acquisition systems, medical electronics, and aerospace applications where component reliability and predictable behavior are non-negotiable. The 1206 package size allows for reasonable power dissipation capability while maintaining the small form factor necessary in modern compact designs. The CAT2A designation within this part number indicates it belongs to AVX's established thin-film resistor series, designed to meet stringent industrial and professional-grade requirements. Components in this family typically exhibit low frequency noise characteristics and excellent frequency response, making them suitable for both DC bias and AC signal applications. In practical terms, engineers might select this specific part number over general-purpose thick-film alternatives when designing precision circuits that operate across wide temperature ranges or demand extended operating life without performance drift. The low 2.2-ohm value makes this part particularly useful in current-limiting applications, shunt circuits for measurement purposes, and impedance matching networks where precise resistance values are critical to system function. The 1206 package format also offers practical assembly advantages. It remains large enough for manual rework if necessary while fitting within the constraints of modern high-density PCB layouts. This balance between precision performance and manufacturing practicality has established the 1206 package as an industry standard across multiple sectors. For engineers evaluating component options, the combination of thin-film construction, established manufacturer provenance, and the 1206 standard package makes this part suitable for applications requiring both precision and reliability in production environments.
