The KNP series wire wound resistors are flameproof, offering excellent electrical and mechanical performance with superior heat dissipation and a low linear temperature coefficient. They provide instant overload capability, low noise figures, and minimal annual shift in resistance values. Compared to enamel types, these resistors are flameproof, lightweight, and more cost-effective. The winding wires are significantly more durable than those in high-temperature produced enamel types.
