Ceramic Case Resistors –
Wirewound / Metal Oxide
SQP Series
Construction
A high purity ceramic rod, with force fit end caps onto which is wound a wire element: or a deposited metal oxide film
(depending on value). The element is fitted into a ceramic case with fireproof insulation cement.

Material
Solderability
Strength
*(Wirewound:: the lower of 5x rated power, or 2.5x LEV for 5 secs. Metal Oxide:: the lower of 6.25x rated power, or 2.5x LEV for 5 secs)
Marking
Type reference, resistance value and tolerance are legend marked onto the upper surface.
Flammability
The resistor will not burn or emit incandescent particles under any condition of applied temperature or
overload.
Solvent resistance
The body protection and marking are resistant to all normal industrial solvents suitable for printed
circuits.
