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.
