12061A4R7CAT4A

The AVX 12061A4R7CAT4A is a thick-film chip resistor designed for general-purpose and industrial electronics applications. This component belongs to the 1206 package family, one of the most widely used surface-mount resistor formats in modern PCB assembly. The 1206 package provides a practical balance between handling ease during manufacturing and board space efficiency, making it suitable for applications ranging from consumer electronics to industrial control systems. Chip resistors in the 1206 package are constructed using thick-film resistive material deposited on a ceramic substrate, then trimmed to achieve the desired resistance value. This manufacturing approach delivers stable performance across typical operating temperature ranges and provides good reliability for long-term field use. The 1206 form factor is large enough to handle moderate power dissipation without excessive heat concentration, yet small enough to support reasonably dense circuit layouts on modern PCBs. The "4R7" designation in this part number indicates a 4.7-ohm resistance value, making this component suitable for low-resistance applications such as current sensing, circuit protection, and signal conditioning stages. Low-value resistors like this are commonly found in power management circuits, load balancing networks, and measurement instrumentation where precise current monitoring or voltage division at low impedance levels is required. The part number also suggests this is from AVX's established resistor catalog, indicating consistent quality and availability for production environments. Engineers typically specify resistors in this category when they need reliable, cost-effective passive components with straightforward performance characteristics. The 1206 package size makes the 12061A4R7CAT4A compatible with standard pick-and-place equipment and wave or reflow soldering processes, reducing assembly complexity and supporting high-volume manufacturing. This part would be selected in preference to surface-mount alternatives when the 1206 footprint specifically matches PCB layout requirements or when compatibility with existing design standards is important. The thick-film construction provides predictable resistive behavior without the frequency-dependent characteristics sometimes seen in other resistor technologies, making this component suitable for both DC and moderate-frequency AC circuits. For industrial and engineering applications requiring straightforward, dependable 4.7-ohm resistive elements in standard surface-mount format, this AVX component represents a mature, widely-supported solution.
