Question: In the design, does the equipment need the resistance value of series resistance and the rated value of the maximum burst current of the equipment? If so, what is it specifically? Can you help me answer?
A: under normal working conditions, keep the holding current of the fuse greater than or equal to the normal working current, that is, ensure Vin/(Rpptc+Rload)<=Ihold. However, the resistance value of the self-recovery fuse under normal operation will not affect the system operation, so the customer selects the value parameter according to actual judgment.
