PTC Resettable Fuses (0ZCG0014FF2C) are devices used to protect against over-currents on electronic circuits. They are also known as positive temperature coefficient (PTC) fuses, which are self-resetting fuses. They consist of a conductive element which is usually a thin film of polymeric material, surrounded by a semi-conductive layer, and a thin wire. This wire is connected to an external circuit element.

PTC Resettable Fuses have multiple applications. First, they are used to protect against damage caused by short circuits and current overloads on electronic circuits. When the current in the circuit exceeds its rated value, the fuse element heats up rapidly, causing the device to open and interrupting the current. This offers maximum protection to the circuit against damage caused by over-currents.

Second, PTC Resettable Fuses are used in power supplies as protection against circuit overloads. In power supply circuits, the fuse element expands when the current exceeds its predefined level, causing the current to be disconnected from the power supply. This helps to avoid any damage to the power supply, protecting it from over-currents.

Third, PTC Resettable Fuses are also used in UPS systems as protection against circuit overloads. In an UPS system, the fuse element expands when the current exceeds its predefined level, causing the current to be disconnected from the UPS system. This helps to avoid any damage to the UPS system, protecting it from over-currents.

The working principle of PTC Resettable Fuses is simple. They operate by responding to changes in temperature. When the current in the circuit increases, the fuse element heats up, causing the element to expand and cut off the current in the circuit. Once the current in the circuit has dropped below the pre-defined level, the fuse element cools down and the device resets itself, allowing the current to flow again.

PTC Resettable Fuses are a great solution for protecting circuits and systems from damage caused by short circuits and current overloads. They are a preferred choice for applications such as power supplies, UPS systems and other electronic circuits, offering efficient and reliable protection. By responding quickly to changes in temperature, PTC Resettable Fuses can help prevent damage and keep your systems running with minimal interruption.
