PTC Resettable Fuses are a type of resettable fuse that uses a PTC (positive temperature coefficient) thermistor. They are commonly used in power supplies, audio equipment, automobiles, communications equipment, and other consumer electronics. The MF-RHT750-2 is a particular type of PTC Resettable Fuse that is used for overcurrent protection.

The MF-RHT750-2 is a single-use device that automatically opens its circuit at a preset threshold when an overcurrent or overtemperature occurs. The fuse then resets by itself after the thermal energy dissipates and current and temperature are normalized back to safe levels. This keeps the protected device from being damaged.

This particular resettable fuse provides overcurrent protection up to a rated current of 750 amperes. The time-delay characteristics are maintained over a wide range of ambient temperatures and loads, ensuring consistent, reliable protection of the intended device. The fuse is also designed so that it will open under fault conditions in less than 10 milliseconds, providing fast and effective protection.

The MF-RHT750-2 has a wide range of applications. It can be used for DC and AC circuits in both consumer electronics and automotive applications. It can also be used in applications where overcurrent protection is required, such as home electronics, industrial equipment, and other regulated systems. The MF-RHT750-2 is an ideal choice for applications where reliability is of the utmost importance.

The working principle of the MF-RHT750-2 involves the PTC thermistor, which is a temperature-sensitive resistor. When current passes through it, the PTC thermistor increases its resistance with increasing temperature. When a preset overcurrent or overtemperature occurs, the thermal energy causes the temperature of the thermistor to rise sharply, causing the PTC thermistor to reach its “trip point”. At this point, the resistance of the PTC thermistor increases dramatically, causing the circuit to open and the device to be protected.

The MF-RHT750-2 is a reliable overcurrent protection device that is suited for a wide range of applications. It is a cost-effective and convenient solution for protecting electronic devices from overcurrent and overtemperature damage. It provides fast and effective protection, allowing for reliable operation of the protected device under normal conditions.
