( XRS-1206-1%1/4W20 ) RESISTENCIA SMD 1206 1% 1/4W 20 OHM

The XRS-1206-1%1/4W20 is a surface-mount film or thick-film resistor in the standard 1206 package size, designed for general-purpose applications in modern PCB assemblies. This component represents a common choice for engineers working with contemporary surface-mount technology, offering the balance of performance and practicality that defines mid-range industrial electronics. As an SMD resistor in the 1206 form factor, this component measures 3.2mm by 1.6mm and mounts directly to PCB surfaces using automated pick-and-place equipment. The 1206 package remains one of the most widely used resistor sizes in industrial electronics, offering a practical middle ground between the smaller 0805 package and larger packages like 1210. This size is large enough to handle reasonable power dissipation while remaining compact enough for dense circuit designs. The 1% tolerance specification indicates this resistor maintains relatively tight dimensional control over its nominal resistance value. Engineers typically specify 1% tolerance resistors in applications where moderate precision is required but tighter tolerances like 0.1% or 0.5% are not necessary. Common applications include signal conditioning circuits, biasing networks, pullup and pulldown resistor arrays, voltage dividers, and general filtering stages in industrial control systems, automation equipment, and consumer electronics. The 1/4 watt power rating reflects a moderate heat dissipation capacity suitable for lower-power signal-level circuits rather than high-current power applications. This power rating is typical for components used in measurement circuits, logic level switching, sensor interfaces, and other signal processing stages where currents remain in the milliamp range. Engineers might specify this exact part number when designing circuits that require the known characteristics of a standard 1206 resistor with predictable performance across typical industrial operating ranges. The combination of package size, tolerance class, and power rating makes it suitable for mixed-signal designs, analog interface circuits, and digital systems that need reliable resistive components without exotic materials or performance specifications. The 20 ohm resistance value positions this component for use in low-resistance applications such as current-sensing networks, impedance matching, or power supply feedback circuitry where this particular resistance value fills a specific functional requirement in the circuit design. This resistor type is suitable for automated high-volume assembly processes, making it economical for production environments while maintaining consistent electrical characteristics across manufacturing batches.
