1206SA680JAT2A

The 1206SA680JAT2A is a surface-mount chip resistor manufactured by AVX, designed for general-purpose applications in industrial electronics, telecommunications, and consumer electronics. This component belongs to the 1206 package family, one of the most widely used standard SMD resistor sizes in modern circuit design. The 1206 form factor measures 3.2mm × 1.6mm, offering a practical balance between compact board space efficiency and adequate power dissipation capability for mid-range applications. Chip resistors of this type serve as fundamental passive components in electronic circuits, providing precise electrical resistance between circuit nodes. They are essential building blocks used in signal conditioning, current limiting, voltage division, impedance matching, and biasing applications across countless industries. The 1206 package is particularly popular in industrial control systems, power management circuits, automotive electronics, medical devices, and infrastructure equipment where reliability and performance consistency matter significantly. The "SA" designation in AVX's naming convention typically indicates this is a standard thick-film resistor element with conventional tolerance and temperature characteristics suited to most general industrial applications. The "680J" portion of the part number indicates the resistance value and tolerance class. Engineers regularly encounter these components in analog signal processing stages, switching power supplies, LED driver circuits, sensor interfaces, and protection networks where the combination of accuracy, stability, and cost-effectiveness justifies specification. One key reason engineers select this specific part number is the assurance of consistent quality and performance from a trusted manufacturer like AVX. AVX's 1206 resistors are manufactured using well-established processes that deliver reliable performance across wide temperature ranges typical in industrial environments. The 1206 package itself has become an industry standard with excellent solderability characteristics and proven long-term field reliability. Compared to larger packages like 1210 or 1218, the 1206 provides a useful compromise when circuit board density is a consideration but component power rating requirements are moderate. Compared to smaller packages like 0805, the 1206 offers improved handling during automated assembly and better thermal performance. For high-volume manufacturing, 1206 components remain cost-competitive while meeting stringent reliability requirements in demanding applications. This part represents a straightforward, dependable passive component choice for design engineers who need proven performance in standard industrial applications without specialized performance requirements. Its widespread adoption across industries ensures design familiarity, manufacturing compatibility, and long-term availability in the supply chain.
