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.

General Note

IRC reserves the right to make changes in product speciﬁcation without notice or liability.

All information is subject to IRC’s own data and is considered accurate at time of printing.
