PTC (Positive Temperature Coefficient) resettable fuses, also known as polymeric positive temperature coefficients or PPTCs, are self-resetting fuses that combine both features of current limiting fuse and self-restarting fuse functions. As a member in PTC resettable fuses family, PFLT.070 is designed with smaller power consumption and display superior performance in extreme temperature and other environmental condition. It is widely used in computers, power supplies, automobiles and other consumer electronic products.

PFLT.070 is an advanced form of PPTCs, but in general, PTC resettable fuses performs the same way. When a current is flowing across a PTC, the resistance will remain constant until either the current reaches to be too high or the temperature reaches to be too hot, which to the point when the current is too high or the temperature is too hot, the PTC resettable fuse will trigger and becomes a very high resistance level that limits the current, effectively protecting the circuit from an electrical overload or short. When the circuit cools down or the overload condition is eliminated, the PTC resettable fuse reset itself and resumes normal operation of the circuit.

PFLT.070 is designed with significant improvement in extreme temperature and other environmental condition than traditional PPTCs. Its advanced resistor technology provides consistent low power consumption with superior performance in temperature change and current change. When working in extreme temperature environment, PFLT.070 is capable of enduring much longer time and still maintain proper operation of the circuit.

Compared to traditional fuses, PFLT.070 exhibits some remarkable advantages, such as adaptability, parts cost saving, and low standby power. Its thermal resistance trigger feature makes this fuse suitable for use in applications such as home power supplies, healthcare device, automotive, industrial electronics, IT networking, etc. With the superior thermal resistivity of the PFLT.070, it is capable of providing secure protection over a wide range of temperature while the traditional fuses would provide limited performance at extreme temperature.

Moreover, compared to the other PPTCs, PFLT.070 is designed with several additional features that provide additional safety. For instance, it comes with an additional fuse burr. This additional fuse burr has a shorter response time than the main PTC element, providing an extra layer of protection against over current and over temperature events. It also features a temperature sensor that can be used to detect any change in temperature that could affect the device or system.

To summarize, PFLT.070 is a highly advanced form of PPTCs, designed with significant improvement in extreme temperature and other environmental condition, excellent thermal resistivity, adaptability, parts cost saving, and low standby power, and additional safety features. These advantages make PFLT.070 a great choice for use in a wide variety of applications, such as medical applications, automobiles, IT networking, home power supplies and industrial electronics.
