Application Notes
The terminations should not be bent closer than 1.6mm from the body of the resistor, and the recommended
bend radius is 1.2mm. Terminations are solderable to within 4mm from the resistor body.
When cold, vitreous enamel has excellent insulation resistance. In common with all insulation materials, the
specific resistance of the enamel decreases with increased temperatures. Therefore, resistors operated at
near-maximum temperature cannot be considered as insulated and should not be used in contact with any
conductive material.
Care must be taken when determining clearance distance between the resistor body and printed circuit board
or other components to ensure these are not overheated. Resistance is measured 6mm from the resistor body.
