SMW591RJT TE Connectivity

SMD Moulded Power Resistor Type SM Series Key Features Low Profile Design Available on Tape Very Wide Value Range Ideal for Power Circuitry Available in 2,3 or 5 Watts Flameproof Coating UL94V0 TEConnectivity(TE)introducesasurfacemountpowerresistorsuitedtomeettoday s circuitdesignneeds.Eachsizeofferslowprofilecasedesignwithflexibletinnedcopper terminations for reliable solder joints. All styles utilize a fully welded construction technique, unlike other designs that rely solely on tinned termination onnections. These features allow the SM Series to withstand the higher temperatures associatedwithreflow,vapourphase,orinfrared(IR)manufacturingprocesseswithout degradation.
