POWER RESISTORS MOR Series: Metal Oxide INTRODUCTION FEATURES Metal Oxide Resistors offer excellent performance in applications where stability and uniformity of characteristics are desired. The complex Oxide materials used gives this series long-term stability, low temperature coefficient and negligible inductance, making it a suitable replacement for carbon composition resistors, high surge/overload capability and flameproof construction make this an alternative for many lower power wire wound resistor. •Excellent long-term stability •Complete flameproof construction •High surge/overload capability •Wide resistance range •Standard tolerance: ±5% (Consult factory for 1% & 2%) •Coating and mark resist Trichloroethylene, Freon, And other cleaning agents. •Improved stability, dissipation, TCR available. Consult factory. •Lower cost alternative to carbon composition resistors. DERATING CURVE 240 100 120 300 200 60 0 0 1 70° 100 500 400 180 Rated Load (%) Temp.
