NOTES:
Test Conditions
For all 0678L data, as well as UL Component investigation, 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), 10mm wide and 100mm overall length.
- UL Condition of Acceptability
- The following information is contained in the UL Component Recognition for 0678L Fuse Series:
The maximum temperature recorded in open air was 100℃ in a 21℃ ambient (79℃ rise). 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.
