PTC Resettable Fuses

PTC resettable fuses are a type of electrical components used to protect components from overload or short-circuited situations. In essence, the fuse’s thermal element will heat up when an overload or short-circuited problem occurs, and will eventually open the circuit to protect the electrical components from damage.The PTCCL05H470FTE is a specific PTC resettable fuse that is part of the “Low Voltage/High Current DC Fuses” series from Littelfuse. It is a fixed 5A rated current fuse with a maximum working voltage of 510Vdc which makes it ideal for protecting high voltage components. The fuse features a low series resistance of only 0.05 ohms and can withstand a maximum continuous operating temperature of 80℃, making it suitable for harsh environment applications.The working principle of the PTCCL05H470FTE is quite straightforward. When an electric current passes through the fuse, its internal thermal element generates heat which is proportional to the current. If the current exceeds a certain threshold, the heat generated will cause the thermal element to open up, thus disconnecting the circuit and protecting the connected components from damage.The applications for the PTCCL05H470FTE are quite varied; it can be used in a wide range of power management applications including solar systems, automotive, medical devices, lighting & power supplies, and LED dimming control systems. Also, it is suitable for high performance circuits which require high level of protection against current overloads, overheating, and electromagnetic interference.Overall, the PTCCL05H470FTE fuse is a reliable, cost-effective, and easy to use solution that provides effective protection against electrical damage and is perfect for a wide range of applications. Its high voltage rating and low series resistance make it suitable for harsh environment applications, while its thermal element ensures that any short-circuit or overload is quickly isolated, thus protecting the connected components from any electrical damage.
