What are the similarities and differences between a disposable fuse and a resettable fuse?
A restorable fuse is essentially a PTC thermistor. It is totally different from a fuse because of its operating principle: it protects a circuit as the resistance of the PTC material is positively correlated to temperature and jump at Curie point.
For the similarities: they both can be used for circuits for overcurrent protection and applied to a number of similar fields and circumstances. Both can be used or replaced in some circumstances. For example, both products are outstanding for battery protection applications where overcurrent protection requirement is not so strict. For protection of certain ICs and important components or at power input/output ends, only the disposable fuse may be competent. The impedance requirement is also higher for these parts. However, the PTC thermistor will be the best choice for the circumstances when products should avoid being damaged from overheat or overcurrent protection at interfaces where hot-swapping is frequent. Yet in most circumstances, the two products are greatly different or cannot replace one another. The following table shows the primary differences between the two.
Owing to the similarities and differences, the two products are available in the market for different purposes.
| One Time fuse | Resettable PTC fuse | |
| Internal resistance | Small | Large |
| Current sensitivity | High | Low |
| Response time | Fast | Low |
| Ageing rate | Slow | Fast |
| Leakage current | None | Yes |
| Safety performance | Strong | Weak |
| Application scope | Wide | Narrow |
