SMW53R3JT 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. The device features a low-profile design with flexible tinned copper terminations and fully welded construction, enabling it to withstand reflow, vapour phase, and infrared soldering processes without degradation. Available in 3-watt power rating with resistance values from 0.1 ohm to 500 ohms, the resistor offers ±5% or ±1% tolerance options and operates at a maximum voltage of 500 volts. With a temperature coefficient of ±200 ppm/°C and insulation resistance of 10,000 MO, this component is ideal for demanding power applications in industrial and consumer electronics where thermal stability and reliability are critical.
