Surface Mount Wirewound Power Resistor TE Connectivity SMW210RJT with Solder Joints and High Load Life
SMD Moulded Power Resistor - SM Series
TE Connectivity (TE) introduces the SM Series, a surface mount power resistor designed for modern circuit applications. Featuring a low-profile case and flexible tinned copper terminations, these resistors ensure reliable solder joints. Their fully welded construction allows them to withstand high temperatures encountered during reflow, vapor phase, or infrared (IR) manufacturing processes without degradation. Available in a wide value range and up to 7 Watts, the SM Series is ideal for power circuitry.
