PTC resettable fuses, also known as polymeric positive temperature coefficient (PPTC) resettable fuses, are fuses that reset automatically after they have been overloaded or fusing. They are used in a variety of industrial applications, including medical devices, consumer electronics, automotive electronics, and renewable energy systems. The MF-R075-2 is a popular choice for applications that require both reliability and cost-effectiveness, and is widely used in a number of industries.The MF-R075-2 is a polymer-positive temperature coefficient (PPTC) fuse with a rated maximum operating temperature of 105°C and a current rating of 75A. Its relatively low resistance allows it to be used in a wide range of applications. It is designed to protect against short-circuits and overloads, and is capable of resetting itself after the current falls below an acceptable level.The MF-R075-2 \'s working principle is based on the "positive temperature coefficient" characteristic of the polymer. It relies on the fact that when a current passes through the PTC, the resistance increases as the temperature increases. As the temperature crosses the threshold, the fuse triggers a current mirroring effect, limiting the current to a safe level. This process of self-triggering occurs numerous times, allowing the device to repeatedly protect itself from overloads.The MF-R075-2 is designed for use in a number of different applications, including automotive systems, consumer electronics, medical devices, and renewable energy systems. The PTC resettable feature makes it ideal for these applications, as it can reset itself multiple times and protect the device from damage. In automotive applications, it is used to protect sensitive electrical components from overcurrent or excessive voltage. It is also used in consumer electronics, for example, to protect against short-circuits in mobile phones. The MF-R075-2 is also used in medical devices to protect against electrical shock and ultimately increase patient safety. In renewable energy systems, it is used to protect batteries from overload and overcharging.Overall, the MF-R075-2 is a popular choice for a variety of applications due to its reliable and cost-effective design. Its PTC resettable feature ensures it can reset itself multiple times in case of an overload, reducing the risk of damage and ultimately increasing safety and reliability. Additionally, the design of the MF-R075-2 allows it to be used in a variety of different applications, making it a versatile and useful device.
