Introduction

PTC Resettable Fuses are a type of component that can protect a circuit from overcurrent, overload, or excess temperature. The PTR016V0160-BK1 is one such Resettable Fuse, and this article will discuss its application field and working principle.

Application Field

The PTR016V0160-BK1 is designed to protect low-voltage circuit boards from current overloads, short-circuits, and over temperature. It is most commonly used in consumer electronics applications, such as laptop computer motherboards, mobile phones, digital cameras, and other similar devices.The PTR016V0160-BK1 can also be used in automotive applications, such as control modules and lighting systems. It is also suitable for other industries, including medical, telecommunications, and industrial automation.

Working Principle

The PTR016V0160-BK1 is a Polymeric Positive Temperature Coefficient (PPTC) element, which contains a special blend of thermoplastic materials. These materials allow the element to have properties that are different than those of traditional fuses. As the current passing through the element increases, the impedance will also increase due to the internal heating of the PTC element. Once the overload current reaches a certain value, the impedance of the element increases exponentially, causing the heat to rise quickly and the current to trip, effectively protecting the circuit from the overload or short circuit.When the fault condition is corrected, the element cools, and the impedance decreases, allowing the current to resume. The PTC element can be reset multiple times without any damage, making them ideal for applications that require frequent resets.

Conclusion

The PTR016V0160-BK1 is a Resettable Fuse designed to protect a low-voltage circuit from over-current, over-temperature, and short circuits. It is suitable for use in a variety of applications, including consumer electronics, automotive, medical, and more. The working principle is based on the principle of Polymeric Positive Temperature Coefficient elements, which limits the current passing through by rapidly increasing its impedance when the current exceeds a certain value. After the fault is corrected, the element returns to its normal state and can be reset multiple times without any damage.
