Bel Fuse offers PTC fuses with an added resettable feature in low-profile, SMT packages


Bel Fuse SMT PTC Resettable Fuses
Bel Fuse’s unique polymer formulation PTC (Positive Temperature Coefficient) devices offer circuit protection, with an added resettable feature in low-profile, SMT packages. Similar to Bel's extensive line of traditional fuse products, the resettable fuses protect against harmful overcurrent and short-circuit conditions. However, the PTC devices can also be used to protect against over-temperature conditions not necessarily caused by excessive current. Bel’s PTC devices will reset after power to the circuit is removed, the fault is cleared, and power is reapplied to the circuit. This reset-ability protects electronic equipment, which remains fully functional, and eliminates the need for service personnel to physically replace a fuse.

PTC devices are used in a wide variety of industrial, computer, battery, consumer electronics, and telecom and automotive applications where they help protect valuable electronic systems and reduce warranty and services costs.
