CONSTRUCTION
MARKING
A high quality ceramic substrate is assembled with
interference fit end caps to which are welded the element
winding and termination wires. The protection is then
applied to the body, providing an effective seal which is
impervious to moisture, shock, vibration, fungus and salt
spray.
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.
TERMINATIONS
Material
Strength
Solder-coated copper clad steel wire.
The terminations meet the requirements of
IEC 68.2.21.
FLAMMABILITY
The resistor coating will not burn under any condition of
applied temperature or component overload.
Solderability The terminations meet the requirements of
IEC 115-1, Clause 4.17.3.2.

APPLICATION NOTES
Type
W31
A
The terminations should not be bent closer than
1.6mm from the body, and the recommended
minimum bend radius is 1.2mm.
63 ± 2
Care must be taken when determining clearance
between the resistor body and the P.C.B. or other
components. Resistance is measured 6mm from
body.
