PTC Resettable Fuses (PPTC) are an important type of overcurrent protection device, used in many consumer, business and industrial applications. They are often used to protect the electronic circuitry found in electrical and electronic devices, such as computers, cell phones, computers and peripherals, home appliances, power supplies, AC/DC adapters, and other electronic systems.

PFNF.150.2 is a specific model in PTC resettable fuse family. It is a device that combines the features of both a Resettable Fuse and a Positive Temperature Coefficient (PTC) element. The purpose of this device is to provide an overcurrent protection solution in the power distribution system, while at the same time offering two levels of current protection, with both high accuracy and low thermal dissipation.

In practical application, PFNF.150.2 is specifically designed for applications with current levels between 5 amperes and 11 amperes, voltage levels between 500 mV and 1000 mV, and temperature range from -55°C to +100°C. It combines the features of both a fuse and a PTPC element, and is used to protect a variety of AC and DC power circuits from over-current and over-temperature damage, and provides reliable protection to the equipment that is connected to it.

PFNF.150.2 has a simple working principle. When the current passes through the fuse device, the heat generated within the PTC element creates a resistive barrier to rising current and temperature, protecting the circuit from overload or over-temperature. This PTC element is designed to reset itself once the overcurrent situation is corrected. This is made possible by the fact that the PTC element can automatically adjust its resistance to keep the current level within the limits of the fuse.

PTFN.150.2 is an ideal choice for applications requiring overcurrent protection with both high accuracy and low thermal dissipation. The device is capable of handling both AC and DC power with fast response time and high operating efficiency. Its excellent characteristics and reliability make it the preferred choice for a wide variety of applications.

In addition, PFNF.150.2 has many advantages over other types of resettable fuses. Some of these include its low power consumption, high current-handling capability, relatively low noise levels, and its ability to withstand longer durations of overload. These characteristics make it suitable for use in devices that require long-term protection.

All in all, PFNF.150.2 is an advanced type of PTC resettable fuse with a wide range of applications in different industries. Equipped with both high accuracy and low thermal dissipation, it is the ideal solution for many overcurrent protection applications. Thanks to its excellent features, it can provide reliable protection against over-current and over-temperature damage, and can also reset itself when needed.
