PTC Resettable Fuses

PTC resettable fuses are a type of circuit protection device designed to provide power and overload protection to a range of applications. The MF-USML175-2 resettable fuse is a popular resettable fuse that is used in various industries. It offers a variety of features that make it an ideal choice for designers and engineers.The MF-USML175-2 is a one-time device that does not need to be replaced after it trips. The device features an integrated polymeric positive temperature coefficient (PPTC) that provides fast and reliable overcurrent protection. The PPTC acts as a thermal switch that will short the current upon sensing an overload, effectively resetting the circuit.One of the major advantages of the MF-USML175-2 is its ability to provide both single-cycle protection and auto-reset protection. The single-cycle protection will trip within milliseconds of experiencing an overload. After the overload has passed, the PPTC will reset, allowing the device to return to normal operation. The auto-reset protection will continue to trip and reset the circuit for subsequent overloads. This feature allows the circuit to be continually protected even in the case of power fluctuations or short-term overloads.The MF-USML175-2 also features an integrated thermal capacitor that ensures smooth and accurate current limiting. The capacitor is designed to keep the device within its temperature limits and provide extra protection from multiple inputs. The thermal capacitor is also designed to absorb and dissipate any energy from a short-circuited output.The MF-USML175-2 is a reliable and efficient device that is designed to meet a variety of application requirements. It can be used to protect sensitive electronics from power and overload issues, as well as providing single-cycle or auto-reset protection. The device is designed to eliminate the need for frequent replacements and enable a more reliable and efficient overall system.In summary, the MF-USML175-2 resettable fuse is a reliable and efficient device that is designed to provide power and overload protection to a range of applications. It features an integrated PPTC that provides fast and reliable overcurrent protection, as well as a thermal capacitor that ensures smooth and accurate current limiting. The device is designed to eliminate the need for frequent replacements and enable a more reliable and efficient overall system.
