APPLICATION NOTES
The terminations should not be bent closer than 1.6mm from the body, and the recommended minimum bend
radius is 1.2 mm. Terminations are solderable to within 4mm from the body.
When cold, vitreous enamel has excellent insulation resistance. In common with all insulations the specifi c re-
sistance 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 the resistor body and printed circuit board or
other components to ensure these are not overheated. Resistance is measured 6mm from the resistor body.
