Resistive Element resistor types have resistance alloy winding braided fiberglass substrate. Intermediate silicone coatings used enhance processibility provide protection resistive element. Termination resistors terminated using alloy coated copper flashed steel lead welded same material. This termination assembly mechanically crimped, utilizing improved crimp design, resistive element. Encapsulation encapsulated utilizing compression molded phenolic plastic material. flame-resistance coating applied over resistive element provide flammability protection when destructive overloads occur. Marking products marked utilizing heat solvent resistant color code bands consistent with EIA/MIL requirements. first band double width designate wirewound construction. fifth band, blue color, used flameproof identification.
