DERATING:
Industrial wirewound resistors have an operating temperature range of -55oC to +350oC
They must be derated at high ambient temperatures according to the curve at the night.
Dielectric Strenght : 1000 van minimum.
Short Time Overload : In intermittent duty the applied power can greatly exceed the wattage rating. However, since each pulse application is somewhat unique, the factory should be contacted for specific requirements.
MATERIAL SPECIFICATIONS :
Core : Steatite. Chemically inert-will withstands severe thermal shock and is impervious to moisture.
Element : Highest quality copper-nickel alloy or nickel-chrome alloy, depending on resistance value.
Coating : HL-special high temperature silicone, Cured at much lower temperatures than vitreous enamels.
