Fuses vs PTCs

Many times choosing between using a Fuse or PTC is a matter of preference, though there are important considerations and common areas of applications where the use of one may be better than the other.

For example, much of the design work for PCs, peripherals, and portable devices (smart phones, tablets, etc.) urges the use of PTCs because they are self-resettable; using a fuse that must be replaced each time an overcurrent condition occurs is unacceptable.

In other cases, fuses may be more acceptable because they completely stop current in fault condition; this may be more desired if safety or avoidance of downstream circuit equipment is a premium concern. Fuses are also helpful for diagnostic purposes, aiding equipment designers and users in tracing the origin of the overcurrent faults.
