POWER RESISTORS RoHS MOR Series: Metal Oxide FEATURES INTRODUCTION 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 * High surge/overload capability * Wide resistance range * Coating and mark resist Trichloroethylene, Freon, and other cleaning agents. * Lower cost alternative to carbon composition resistors.
