The maximum temperature recorded in open air was 135 in a 25 ambient (110 rise). Consideration should be given to checking operating temperatures in end-use application with regard to thermal index of surrounding materials and components. Remark: The marking on fuse shall be facing upward on PCB. Caution: - Minimum fusing point: The 0684L 40A fuse is NOT intended to be operated at currents between 100% and 200% of ampere rating. Prolonged operation at currents in this range may result in overheating of the fuse and/or desoldering of the fuse caps from the PCB pad.
