PTC resettable fuses, also known as poly-fuse, are self-resetting fuses used in a wide variety of electronic appliances and circuits. In this article, we\'ll discuss the application field and working principle of the PTC Resettable Fuse, Model PFRA.110.2.

In today\'s wired world, it\'s important to have an efficient and reliable power supply for electronic devices and circuits. A PTC resettable fuse is the perfect choice for many applications, such as communicating between devices, interfacing with automotive electrical systems, and protecting sensitive circuits from power surges.

As its name implies, the PTC resettable fuse, Model PFRA.110.2, utilizes a thermally sensitive polymer material in order to regulate the flow of current. The polymer material has a high resistance at low temperatures, but as the temperature rises, its resistance decreases, allowing more current to pass. As the current increases, it triggers a thermal reaction that increases the temperature of the polymer further, thus increasing its resistance, limiting the current. This makes the fuse self-resetting, providing protection from short circuits and other dangers.

The PFRA.110.2 series resettable fuses use a multi-layered structure that comprises both a metal and thermally sensitive material. This ensures that when the fuse experiences a large current surge, it can reset itself quickly and accurately. Furthermore, the package is designed such that the fuse has a low thermal mass which allows for fast thermal recovery and resetting of the fuse.

The PFRA.110.2 series is ideal for applications where space is limited. The fuses come in a range of sizes and are designed to fit into tight spaces. Furthermore, the fuses are designed for ease of installation, as they often come pre-assembled with terminals ready to be connected to the power source.

Another great feature of the PFRA.110.2 series is its high current handling capability. The fuses can handle up to 10 amp current safely and reliably. This makes it ideal for applications such as motor controllers, automotive systems, home appliances, and other electronic circuits requiring high currents.

The PFRA.110.2 series is also designed to be highly reliable and long-lasting. The fuses are rated to last up to 2000 hours of operation, making them suitable for applications that require long-term protection from high currents. Furthermore, the fuses are capable of withstanding a wide range of temperatures, making them suitable for use in hot or cold environments.

In summary, the PFRA.110.2 series of PTC Resettable Fuses are ideal for a wide range of applications, especially those involving high currents. They are compact, can handle up to 10 amp current, and are designed to reset quickly and reliably. Furthermore, they are rated to last up to 2000 hours and can withstand a wide range of temperatures. With these features in mind, it\'s easy to see why the PFRA.110.2 series can be relied upon to provide reliable and efficient current protection.
