SP21K5FT

SMD Precision Power Resistor Type S Series Key Features Low Profile Design Tape and reel packaging Wide Value range Up to 3W Power With this robust wire wound resistor, one design concept allows an engineer to choose from three styles (Lo Ohm, Power, or Ultra Precision) while staying within the new standard circuit board land pattern guidelines now accepted by the wirewound resistor industry. Each size offers low profile case design with flexible tinned copper terminations for reliable solder joints. All styles utilise a fully welded construction technique. These features allow the S Series to withstand the higher temperatures associated with reflow, vapour phase, or infrared (IR) manufacturing processes without degradation.
