Marking
W31 resistors are legend marked with type reference,
resistance value and tolerance. Values are marked in
accordance with IEC 62.
Solvent Resistance
The body and marking are resistant to all normal industrial
cleaning solvents suitable for printed circuits.
Flammability
The resistor coating will not burn under any condition of
applied temperature or component overload.
