SMW5R33JT 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 resistor 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. Based on the SMW designation and part numbering scheme, this is a 5-watt wirewound resistor with 1% tolerance (F-grade), offering resistance values from 0.1 ohm to 500 ohms with a maximum operating voltage of 500 volts. The device exhibits a temperature coefficient of ±200 ppm/°C across the -55°C to +200°C range and maintains excellent stability under load life and humidity conditions. Its flameproof UL94V0 coating and high insulation resistance of 10,000 MO make it suitable for demanding industrial and power supply applications where durability and thermal performance are critical.
