PTC Resettable Fuses are devices designed to protect electronic circuits from overcurrent or overvoltage faults, preventing potential damage to circuitry, and ensuring a reliable circuit operation. The MF-RHT700-AP is a surface-mountable resettable fuse from Schurter, offering a wide variety of features and benefits.

The MF-RHT700-AP is a polymeric positive temperature coefficient (PPTC) resettable fuse, designed for SMD-mounting. This device is suited for use in applications requiring higher current ratings. It offers high energy absorption capabilities, with a maximum current absorption of up to 700A peak, and can be operated with currents up to 20A.

The MF-RHT700-AP is designed to guarantee superior protection against overcurrents, with a fast and reliable response. It features fast fault shutdown, high accuracy trip current settings, and low temperature dependence. The trip current of this device can be adjusted to meet specific application requirements, and it offers long-term protection against both direct and reverse overloads.

In addition to providing short-circuit and overload protection, the MF-RHT700-AP also offers protection against excessive temperatures. It is designed to automatically reset once the temperature drops below the set-point. This device also features an overvoltage protection, protecting the circuit from damaging voltage spikes. This device offers superior protection against power surges and voltage transients.

The working principle of the MF-RHT700-AP is not complicated, as PTC resettable fuses work in a similar fashion to regular fuses. Like a regular fuse, the MF-RHT700-AP features two electrodes, which are connected to each other by a polymeric material. The device is designed to detect an overvoltage or overcurrent, and in such case, the polymeric material will increase its resistance, interrupting the circuit.

Once the device has tripped, it will remain in a dormant state until the current or voltage returns to an acceptable level, at which point the device will reset automatically. This means that the MF-RHT700-AP is a non-destructive device, meaning that it can be re-used and does not require replacement after each overcurrent or overvoltage event. This makes it an ideal choice for applications with a high risk of overvoltage or overcurrent.

The MF-RHT700-AP resettable fuse is an ideal choice when it comes to providing reliable and efficient protection against a high risk of overcurrent and overvoltage events. This device offers a fast response, superior energy absorption capabilities, and can be operated with currents up to 20A. In addition, its adjustable trip current makes it ideal for a wide range of applications.
