Consideration should be given to checking operating temperatures in end-use application with regard to thermal index of surrounding materials and components. (Maximum temperature recorded at 80% of rating (24A) for the 0678L 30 rating was 69 (48 rise). Caution: - Minimum fusing point: The 0678L Series fuse are 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.
