Type SQ Series
1773285 CIS BI 06/2011
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.
