Metal Oxide Resistors - 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. Metal Oxide Types include high power and flameproof axial through hole and surface-mounted devices. Token Metal Oxide Resistors are primarily designed for power resistor lines and conform to the RoHS directive and Lead-free. Metal Oxide resistors can be customed designs and tighter tolerances available on request. Application of metal oxideresistors specific designs also available including different power size and resistance specifications adjusted to resistance requirements.
