1206GA390JAT3A

The 1206GA390JAT3A is a thick-film chip resistor manufactured by AVX in the widely-used 1206 surface-mount package. This component is designed for general-purpose resistive applications in electronic circuits and serves as a fundamental building block in countless industrial and consumer electronics designs. Thick-film chip resistors like this part are constructed by depositing a resistive material onto a ceramic substrate, then trimming to achieve the target resistance value. The 1206 package designation refers to metric dimensions of approximately 3.2mm by 1.6mm, making it a standard mid-size surface-mount component that balances ease of handling with reasonable power dissipation capability compared to smaller alternatives. This size is popular in both automated and manual assembly environments. The "GA" prefix in AVX's part numbering typically indicates general-purpose thick-film resistor technology. These components are well-suited for applications where cost-effectiveness and reliable performance across a broad operating range are priorities. Engineers commonly specify thick-film resistors in power supplies, signal conditioning circuits, impedance matching networks, timing circuits, and protective resistance applications. Industrial and engineering buyers select the 1206 package when circuit layouts require compact form factors but need better current handling than smaller packages like 0805 or 0603 can provide. The package's moderate size allows it to dissipate more power than its smaller counterparts while still fitting efficiently on modern PCBs. This makes 1206 resistors particularly valuable in industrial control systems, measurement instrumentation, telecommunications equipment, and automotive electronics. Thick-film resistors in general offer stable resistance values across temperature ranges typical in industrial environments. They typically exhibit predictable behavior and are cost-effective for high-volume production, which is why they remain ubiquitous in industrial applications despite the availability of thin-film alternatives. When selecting this specific part number, engineers value the consistency of AVX's manufacturing quality and the widespread familiarity with the 1206 package in design and manufacturing workflows. The part integrates easily into existing supply chains and is compatible with standard PCB assembly processes, soldering profiles, and testing procedures. For circuit designers working on industrial control systems, embedded instrumentation, or other reliability-critical applications, standardizing on established components like the 1206GA series from recognized manufacturers reduces design risk and accelerates time to market.
