Derating must be applied when resistors are
mounted on a heat sink of smaller dimensions than
defined in the table for reference heatsink.
It is recommended that the resistor base should be
coated with silicone grease before mounting to
obtain the stated operating characteristics.
The grease increases thermal conductivity to the
heatsink.
After soldering care should be taken to ensure that
there are no flux residues on the moulding
compound, otherwise insulation resistance will be
reduced.
PACKAGING
Resistors are packed in plastic bags and boxed for
maximum protection.
WH50 ONLY
To load at maximum commercial rating (50W) mount
on heatsink 30.5cm x 30.5cm x 1.5mm.
