Note: A 0.05 ohm addition is to be added to the performance of all resistors < 10 ohms.
Application Notes
After soldering care should be taken to ensure that there are no flux residues on the end faces of the moulding
compound, otherwise insulation resistance will be reduced. The minimum surface tracking distances from termination
to casing are shown in the Physical Data tables as dimension Dt.
It is recommended that the resistor base should be coated with heatsink compound before mounting to obtain the
stated operating characteristics. The heatsink compound increases thermal conductivity to the heatsink.
