1206PC393KAT1A

The 1206PC393KAT1A is a thick-film chip resistor manufactured by AVX, designed for applications requiring reliable, compact passive resistance in surface-mount configurations. This component belongs to the general class of fixed resistors used across industrial electronics, telecommunications, power supplies, and consumer electronics where space constraints and high-volume manufacturing make chip resistor packages essential. The 1206 package designation refers to the component's physical dimensions in metric terms, indicating a compact rectangular format suitable for automated pick-and-place assembly on printed circuit boards. This standardized package size has become ubiquitous in modern electronics manufacturing, allowing for efficient board layout and compatibility with standard soldering processes. Thick-film resistors like this model are constructed by depositing resistive material onto a ceramic substrate, then adding protective coating and terminations, which provides good stability and reliability for industrial applications. Thick-film chip resistors are specified when designers need a balance between cost-effectiveness and performance. Compared to thin-film alternatives, they offer adequate stability for most industrial and commercial applications while maintaining lower production costs. They perform well in temperature-cycling environments typical of industrial equipment, automotive systems, and outdoor installations. The AVX brand carries a reputation for manufacturing components to consistent quality standards, making this part suitable for applications where repeatability and long-term reliability matter. Engineers might select the 1206PC393KAT1A specifically when their circuit design calls for a resistor value in the range indicated by the alphanumeric code, combined with the physical and electrical characteristics associated with this package and manufacturer's process. The 1206 package offers advantages over smaller packages like 0805 when slightly higher power dissipation is required, while remaining significantly smaller and more cost-effective than larger packages. Its standardized nature means wide compatibility with contract manufacturers and assembly services globally. Common application areas include signal conditioning circuits, impedance matching networks, pull-up and pull-down resistor networks, voltage dividers, and current-limiting functions in industrial control systems. The component's reliable performance across extended temperature ranges makes it suitable for equipment that experiences thermal cycling or operates in non-climate-controlled environments. For engineers evaluating alternatives, this part represents a proven, mature solution from an established manufacturer. The combination of standardized package, established supply chain, and consistent performance characteristics makes it a straightforward specification for designs requiring dependable passive resistance without specialized requirements like precision tolerance or extreme environmental ratings.
