Construction

This flexible range of Power Wirewound Resistors either have wire or power oxide film

elements. The SQ series resistors are wound or deposited on a fine non - alkali ceramic core

then embodied in a ceramic case and sealed with an inorganic silica filler. This design provides

a resistor with high insulation resistance, low surface temperature, excellent T.C.R., and

entirely fire proof construction. These resistors are ideally suited to a range of areas where low

cost, and efficient thermal performance are important design criteria. Metal film cores adjusted

by laser spiral are used where the resistor value is above that suited to wire. Similar

performance is obtained although short time overload is slightly derated.
