12061A3R3CAT2A

The AVX 12061A3R3CAT2A is a thin-film chip resistor designed for precision applications requiring tight tolerance and stable performance across temperature ranges. This component belongs to AVX's established line of high-reliability resistors commonly specified in industrial, medical, aerospace, and telecommunications equipment where consistent electrical behavior is critical. Thin-film resistors like this part are manufactured using advanced deposition techniques that create a precise resistive layer on a ceramic substrate, resulting in superior stability compared to thick-film alternatives. The 1206 package designation indicates a surface-mount device measuring 3.2mm by 1.6mm, making it suitable for compact circuit board layouts while remaining large enough for standard pick-and-place assembly equipment. This mid-range package size offers practical handling characteristics for both automated production and repair operations. The "3R3" designation in the part number indicates the nominal resistance value. Components in this resistance range are frequently used in bias networks, pull-up and pull-down circuits, impedance matching applications, and sensor signal conditioning. The "CA" suffix typically identifies this as belonging to AVX's precision resistor family with controlled tolerance specifications suitable for analog circuit applications where accuracy directly impacts system performance. Engineers typically specify thin-film chip resistors from this series when designs require predictable temperature coefficients, low noise characteristics, or stable behavior over extended operating life. These resistors perform well in applications involving precision instrumentation, data acquisition systems, audio signal paths, and feedback networks in control circuits. The inherent stability of thin-film construction makes this part preferable to standard thick-film alternatives in circuits where component drift could compromise accuracy or introduce unwanted signal distortion. The 1206 form factor also provides adequate power dissipation capability for moderate-power applications, though actual power ratings depend on PCB layout and thermal management conditions. This size strikes an effective balance between thermal performance and component density, making it a standard choice for mixed-signal board designs that cannot accommodate larger packages but require more precision than smaller alternatives provide. Designers working with legacy systems or existing reference designs often encounter this part number, as AVX's resistor series maintains consistent specifications across production lots, supporting long-term availability and design continuity. For applications where component specifications are mission-critical or where supply chain stability matters, verified sourcing of genuine AVX parts ensures performance matches original design intent.
