YQZ120N0013

PTC (positive temperature coefficient) resettable fuses are versatile components within the electric appliance industry, and among these components, the YQZ120N0013 is particularly useful for helping to protect sensitive electronics from power faults and other potential damages. In order to understand the scope of its applications, as well as its working principle, this article will explore both of these aspects of the YQZ120N0013.

Application Field

The YQZ120N0013 is a PTC resettable fuse with a 120V, 0.13A rating and a 15A capability. It has a range of application fields, since it is ideal for protecting circuits that carry sensitive components, such as digital logic circuits, as protection against electrical shock, as a fuse for use in applications with infrequent maintenance, and as a protection against grounding faults, among other scenarios. The YQZ120N0013 is also a perfect choice for applications that require reliable and frequent over-current protection, such as amplifiers, switches, and light bulbs.

The YQZ120N0013 also has an advantage of being highly resistant to any changes of temperature or voltage, making it perfect for harsh and demanding environments. Furthermore, the fuse boasts a minimum operational temperature of -40°C and a maximum of 85°C, showcasing its versatility when it comes to possible applications.

Working Principle

PTC resettable fuses work on the principle of heated elements and predetermined amperage. In the case of the YQZ120N0013, the fuses are formed of two positive temperature coefficient (PTC) elements which have a zero resistance when cold and an increased resistance when subjected to even a slight increase in temperature. As the current passes through the fuse, it causes the wire to heat up, and when its temperature reaches a predetermined level, the PTC element will activate and open the circuit; therefore interrupting the current.

The YQZ120N0013 operates in a unique way compared to other resettable fuses. With these types, the PTC elements open the circuit under overload or fault condition, and only reset when the power supply is disconnected and reconnected. However, the YQZ120N0013 has a dual action mechanism, so it will open the circuit with a short overload or fault condition, and also remain closed with a short constant current. This ensures a higher level of protection for any sensitive electronics connected to the circuit.

Conclusion

In conclusion, the YQZ120N0013 is a useful and versatile PTC resettable fuse with a range of potential applications. It offers superior protection for sensitive electronics against power faults, and the unique dual action mechanism ensures a higher level of protection compared to other resettable fuses. As a result, the YQZ120N0013 is an ideal component for a range of electric appliance industry settings.
