metal oxide resistors - rss, rsn series

oxide,resistor

rss and rsn series have a resistance element formed by the oxidation reaction of a vapor or spray of tin chloride solution on the heated surface of a glass or ceramic rod. the resulting tin-oxide film is adjusted to value by cutting a helix path through the film. it can sustain high temperatures and electrical overloads, and supports moderate-to-precision attributes. types include high power and flameproof axial through hole and surface-mounted devices.
