The ROX series of resistors comprise of a metal oxide film deposited onto a high quality alumina former. Attention to materials and processing quality allow a reduced physical size for each of the three power ratings with very good long term stability. The end cap and welded wire construction ensure high mechanical stability and strength. A specially formulated coating protects the element from environmental conditions and will withstand overload conditions without flame or mechanical damage. Recommended uses include all applications where overload conditions must not cause flaming. Value and tolerance markings is by four band colour code in accordance with IEC62. Rated at 70°C mounted horizontally in free air. Climatic category 55/235/56.
