PTC Resettable Fuses

PTC resettable fuses represent a class of circuit-protection devices that are typically used for the purpose of limiting short-term currents in higher voltage circuits. These fuses are often called “resettable fuses” because they are designed to automatically resetonce the over-current condition has been removed and the fuse element has cooled. Each device has its own specific application field and working principle.

An example of such a device is the 0ZCC0160AF2C resettable fuse, which is a current-limiting device that utilizes a thermally sensitive PTC element as its main active component.

Application Field

The 0ZCC0160AF2C device is rated for a maximum operating temperature of +85°C, with a maximum voltage of 160VAC. It is designed to provide general-purpose protection for automotive electronics, AC/DC adapters, household appliances, and semiconductors. This resettable fuse is ideal for applications where space-saving due to its small package size and fast response are required.

Working Principle

The 0ZCC0160AF2C device works on the principle of PTC thermistor-based over-current protection. It utilizes a thermally sensitive PTC element which increases its resistance with increasing temperature. This structure provides the advantage of having accurate current limiting capabilities and fast trip times.The PTC element is located in the center, surrounded by a pair of electrodes which are connected to the input and output terminals, respectively. When an overload current occurs, the PTC element heats up and increases its resistance, effectively limiting the current flow. Once the temperatures are reduced to a safe level, the PTC element cools down and returns to its original low-resistance state, allowing normal current flow.

The 0ZCC0160AF2C has a variety of safety features, including anfuses anti-parallel diode which prevents any reverse-flow of current. It also uses a safety gap between its PTC element and accompanying electrodes in order to make sure that the thermal effect of the PTC element does not cause any secondary effects on other components within the circuit,

The 0ZCC0160AF2C is a very useful tool for providing circuit protection and ensuring that critical circuits are not damaged by over-currents. It is well-suited for applications that require fast response times, accurate current limiting, and space-saving design.
