PTC resettable fuses are a type of circuit protection device with an integrated bimetallic element that is designed to protect a circuit against overload. PTC resettable fuses are constructed with metal parts and a polymer disc. The disc contains a conductive core material which is exposed to an electrical current passing between two metal contacts that are mounted on the disc.

When the current flowing through the PTC resettable fuse reaches the device’s rated current level, the heat generated by the current causes the PTC element’s resistance to increase significantly. This sudden increase in resistance will cause the current to drop, thereby causing the device to trip. The increased resistance continues until the power or current has been discontinued for a period of time, and the device then automatically resets and returns to its original resistance state.

The 0ZCM0012FF2G PTC resettable fuse is a surface mount type device housed in a 1205 package. This device is designed for general overcurrent and overvoltage protection including applications in data and telecom systems, audio and video systems, industrial control systems, computer peripheral systems and uninterruptable power systems. The device can be triggered at currents up to 12A and has a working voltage of 16V. The 0ZCM0012FF2G is designed to protect against short circuits, accidental exposure to high currents, and other unexpected events and conditions that can cause harm to a circuit.

The working principle of 0ZCM0012FF2G PTC resettable fuse is simple and reliable. The device allows current to pass through the circuit normally and monitors the current levels, tripping if the current exceeds the rated threshold. Once tripped, the device will remain in a non-conductive state until the current drops, at which point it will automatically reset and return to a state in which it will accept current.

In short, the 0ZCM0012FF2G PTC resettable fuse is designed for overvoltage and overcurrent protection in a variety of applications. The device’s integrated bimetallic element is designed to protect the circuit against overload and trip in the event of an overvoltage or overcurrent situation. The device is capable of self-resetting once the current levels drop, allowing the circuit to resume normal operation.
