PTC resettable fuses or Positive Temperature Coefficient resettable fuses are specialized electric devices used as primary or secondary overcurrent protection in a variety of electronic equipment. They are also known as resettable fuses, polymeric positive temperature coefficient (PPTC) fuses, polyfuses, or Multifuse. This type of fuse can be reset to active mode after an overcurrent fault, when current flow is restored to normal.

PTC resettable fuses feature a unique design in which two sets of elements are arranged and connected within a single housing. The 0ZRE0075FF1A model belongs to this family, and it is used in the protection of portable electronic devices, including notebook computers, smartphones, and digital cameras. It is also employed in power adapters, power drills, small household appliances, and in other household and industry applications.

The 0ZRE0075FF1A PTC resettable fuse provides a variety of overcurrent protection options, including over-temperature protection, short-circuit protection, and power-surge protection. It is specifically designed to offer reliable protection from high-current overloads, while also allowing for easy resetting after the fault has been corrected.

The 0ZRE0075FF1A has an operating temperature range of -40°C to +125°C, and a maximum operating current of 10A. The fuse has a voltage rating of 20V and a resistance rating of 0.014 ohms. The 0ZRE0075FF1A has a time-delay which is adjustable, allowing it to be tailored to suit the application. When an overcurrent fault occurs, the 0ZRE0075FF1A will open the circuit, cutting off the current flow, thus protecting the connected electronic components.

The time-delay feature of the 0ZRE0075FF1A PTC resettable fuse allows it to be used in applications where the fault occurs intermittently, as it will not deactivate if the current is restored to within normal operating range within the delay time.

To reset the fuse, two pins on the edges of the unit must be shorted. This causes the internal thermistor to increase in temperature, activating the reset mechanism. Once reset, the 0ZRE0075FF1A will start functioning again, permitting current flow in the circuit.

The 0ZRE0075FF1A PTC resettable fuse is designed to be used as a primary or secondary component in electrical circuits. It provides reliable protection from overcurrent faults, power-surges, and short-circuits, while also allowing for easy resetting with just two shorting pins. The 0ZRE0075FF1A is ideal for use in a variety of portable electronic devices, in power adapters, and in other household and industry applications.
