Type SQ Series
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.
