简 介:Beryllia Core, Silicone Coated Power Resistors MIL-R-26 (RW) & Commercial Industrial Styles
B Series
IRC "B" Series resistors offer power ratings up to 4 times highere than standard power wirewound resistors of equal size. This is made possible due to a ner heat dissipation pattern. The Series "B" resistors will equal the same stability and environmental requirements of lower rated conventional resistors.
Electrical Data
Heat Dissipation Power Rating Power to Size Ratio Wattage Beryllia core provides nest possible pattern Up to 4x higher than conventional resistors, depending upon physical size 35% to 400% greater than standard silicone coated types 1 watt to 18 watts ± 20 ppm/°C 10up ± 50 ppm/°C 1 to 9.9 ± 400 ppm/°C 0.5 to 0.499 ± 650 ppm/°C 0.1 to 0.499 22 special T.C.’s available from -20 ppm to +6000 ppm ± 1% to + 0.1% From .1 to 150K Special high temperature silicone coating, impervious to moisture, salt water immersion, and abrasion Tinned copperweld is standard 500 volts AC for B-1, B-2, B-3; all others 1000 volts 5000 megaohms minimum dry
