Agency Approvals 0684L9400-X1 40A 0.0016 0.15 See Table of Safety Approvals on Page 1 for Voltage and associated Interrupting Ratings 195 Y Consult manufacturer for other ratings NOTES: Test Conditions All tests were conducted with fuse samples soldered on a PCB (1.6mm thick) test board with copper traces measuring 0.1mm nominal thickness (3 oz. clad), 25.4mm wide and 100mm overall length. 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.
