SMW51R5JT 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 4 ratings up to 7 Watts Flameproof Coating UL94V0 TE Connectivity (TE) introduces a surface mount power resistor suited to meet today s circuit design needs. Each size offers low profile case design with flexible tinned copper terminations for reliable solder joints. All styles utilize a fully welded construction technique, unlike other designs that rely solely on tinned termination connections. These features allow the SM Series to withstand the higher temperatures associated with reflow, vapour phase, or infrared (IR) manufacturing processes without degradation. Now also available at 7W power rating.
