1812WA820JAT1A

The 1812WA820JAT1A is a thick-film chip resistor manufactured by AVX, representing a reliable passive component widely used in industrial electronics, telecommunications, and consumer equipment applications. This resistor belongs to the 1812 package family, which denotes its physical dimensions and form factor—a surface-mount rectangular component measuring approximately 4.5mm by 3.2mm, making it suitable for modern printed circuit board assembly processes. Chip resistors in the 1812 package class are engineered for applications requiring a balance between power handling capability and compact board space. The thick-film construction technology used in this component provides stable resistance values across operating conditions, making it appropriate for general-purpose industrial and commercial electronics rather than precision analog or measurement applications. These components are commonly encountered in power supply circuits, signal conditioning stages, biasing networks, and other non-critical resistive functions where cost-effectiveness and reliability are paramount. The AVX 1812WA series represents a standard commercial-grade resistor line designed for straightforward industrial applications. Engineers typically specify components from this family in environments where component robustness and long-term stability matter more than exceptional tolerance or temperature coefficient performance. The 1812 package size offers practical advantages over smaller packages (0805, 0603) when moderate power dissipation is required, while remaining smaller and more cost-efficient than larger packages for applications that don't demand exceptional power ratings. Common application areas include consumer electronics power management, industrial control circuits, telecommunications equipment, automotive electronics, and general-purpose industrial instrumentation. The thick-film technology provides adequate performance in these segments, with resistance values maintained reliably across normal operating temperature ranges and supply voltages encountered in standard industrial environments. Engineers might select the 1812WA820JAT1A specifically when their circuit design calls for this particular resistance value in a standard surface-mount format, and when the resistor's performance characteristics align with non-demanding applications. The combination of proven AVX manufacturing quality, standard package geometry, and established supply chain availability makes this part a practical choice for mainstream industrial designs seeking cost optimization without sacrificing basic reliability requirements. The part number nomenclature indicates a specific resistance value and manufacturing configuration within AVX's product catalog. As with all passive components, proper board layout considerations—including adequate spacing from heat sources and appropriate trace routing—contribute to optimal field performance.
