APPLICATION NOTES
The termination should not be bent closer than
1.6mm from the body, and the recommended
minimum bend radius is 1.2mm. The terminations
are solderable to within 4mm from the body.
When cold, vitreous enamel has excellent insulation
resistance. In common with all insulants
the specific resistance of the enamel decreases with
increase in temperature. Therefore, resistors
operated at near maximum temperature cannot be
classed as insulated and should not be used in
contact with any conducting material. Care must be
taken when determining clearance distance between

PACKAGING
For W21 and W215 the standard method of
packaging is taped in Ammo Packs. For W22 the
standard method of packaging is taped and reeled.
Alternatives available by special request are detailed
in the table below.
W23’s and W24’s are available only as loose packed
in boxes. W series resistors can bbe supplied
preformed. Contact factory for details.
the resistor body and the printed circuit board or
other components to ensure these are not over
heated. Resistance is measured 6mm from body.
