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.
