PTC Resettable Fuses are the perfect solution for Circuit protection, safety, and reliability. They enable an application to remain in a functional state after an overload or surge condition has been resolved.PTC Resettable Fuses are generally composed of PTC and fuse elements, with a variety of choices available in terms of current, trip characteristics, form factor, package selection and mounting options.The PFMU.005.2 is a high-complexity Resettable Fuse module that offers multiple protection functions and lowest resistance for the application.

Application Field: Resettable fuses are increasingly used as a circuit protection device in a variety of applications, such as consumer electronics, automotive and medical systems. With its multi-protection functions, the PFMU.005.2 can be used in a variety of applications that require high current with low resistance. These include industrial, automotive, home appliance, home automation, and other consumer applications.

Working Principle: The working principle of the PFMU.005.2 is based on a PTC (positive temperature coefficient) resistor element and a fuse element. The PTC element acts as a current and temperature limiter, with its resistance increasing with increasing temperatures and high temperatures leading to permanent resistance even after the temperature has returned to normal. This means that when an overcurrent occurs, the PTC element instantly increases its resistance to limit the current and prevent further damage from occurring. The fuse element acts as a primary current limiter, since it will open or "blow" when the current reaches a certain level. The PFMU.005.2 also has a self-resetting function, which means that after clearing the excess current, the device will automatically reset itself and be ready to operate again.

The PFMU.005.2 is a two-element, dual-mode, resettable fuse module that provides maximum flexibility and total application protection. It offers multiple protection functions and it is compliant to international standards such as UL, CSA and VDE. It has high overcurrent and overvoltage protection capabilities, low resistance, high frequency performance, and can be used in a variety of applications. The module also has a small size, making it ideal for space constrained applications.

PFMU.005.2 Resettable Fuses offer a great protection solution for a wide range of applications, and they are easy to use and install. They provide reliable protection against overcurrent and overvoltage, as well as excellent performance in high-frequency applications. They also offer a fast resetting time and self-resetting capabilities that enable the device to remain in a functional state after an overload or surge condition has been resolved.
