SMW21R0JT is a surface-mount moulded power resistor from the TE Connectivity SM Series, designed for power circuitry applications requiring reliable performance in high-temperature manufacturing environments. This 2-watt wirewound resistor features a 1.0 ohm resistance value with ±1% tolerance, a maximum operating voltage of 300 volts, and a low-profile design with flexible tinned copper terminations. The resistor utilizes fully welded construction and a flameproof UL94V0 coating, enabling it to withstand reflow, vapour phase, and infrared soldering processes without degradation. With an insulation resistance of 10,000 MO and a temperature coefficient of ±200 ppm/°C across the -55°C to +200°C range, this component is ideal for industrial power applications, power supply circuits, and other demanding electronic systems where thermal stability and reliability are essential.
