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.
