How much voltage drop will there be on the polymer self-recovery fuse

Question: How much voltage drop will there be on the polymer self-healing fuse?
 
A: Different circuits are different. Generally speaking, if the balance resistance and current are known, the voltage drop can be calculated. The maximum voltage drop of polymer self-recovery fuse is calculated according to the resistance value r1max; The typical voltage drop of can be calculated without Rmax according to Rmax or the average of Rmin and r1max. If IH is the normal working current and r is the resistance r1max of the polymer self-recovery fuse, (Rmax or (Rmin r1max)2), then the voltage drop on the polymer self-recovery fuse in the circuit is: vdrop = ih x r.
