!Note
"POSISTOR" is a circuit protector whose resistance
value in normal operation is very low and in abnormal
situations like overcurrent or overheating, will be
increased to restrain overcurrent. "POSISTOR" can be
used for overcurrent protection against current fuse
or temperature fuse, due to its ability to return to
its initial condition when overcurrent is removed.
1. Best suited to meet the requirements for power
2. Circuit is protected until current is turned off.
3. Restores the original low resistance value
4. Non-contact design leads to long life and no noise.
