PTC Resettable Fuses are widely used in circuit protection. The YPAL0013T is a PTC resettable fuse developed by LEOSLIC. It is generally used for overcurrent protection applications and is suitable for one-way electrical connection protection. It can protect against overvoltage, reverse connection, and inrush current surges.The YPAL0013T adopts a ceramic material as the main material, and a printed circuit board as a substrate. It has an overcurrent detection resistor in the middle of the fuse. This resistor detects whether the current flowing through the circuit meets the working requirements. If the current exceeds the rated current of the fuse, this resistor will produce a large amount of heat. At this time, the temperature of the fuse rises sharply, which causes the fuse to reset. This prevents the circuit from continuing to be overloaded.When the current falls below the rated current, the temperature of the fuse will gradually decline. At this time, the fuse will reset itself. As long as the current is within the rated current, the fuse will be kept in a normal state.The working principle of YPAL0013T is mainly based on the Fridge phenomenon. When the initial current flows through the overcurrent detection resistor, the resistor generates heat, which causes the temperature of the fuse to rise. When the temperature reaches a certain value, the ceramic material will expand and rupture. This rupture will cause a short circuit that will interrupt the circuit, and the fuse will be reset. When the fuse is reset, the overcurrent detection resistance will return to its original state. The temperature of the fuse will drop and the fuse will reset itself.The YPAL0013T is suitable for applications involving low-voltage AC/DC, such as computers, TV sets, DVD players, stereo systems, game consoles, and other electronic equipment. It is also applied in battery-powered electronic products and electrical circuit protection of solar photovoltaic systems. With the high temperature melting, it can play a role in avoiding the burned parts, damaged parts, and overall failure of the components due to long-term overload.In conclusion, the YPAL0013T is a PTC resettable fuse designed by LEOSLIC. It is generally used for overcurrent protection applications and is suitable for one-way electrical connection protection. It can protect against overvoltage, reverse connection, and inrush current surges. Its working principle is based on the Fridge phenomenon, which enables it to reset automatically after an overload occurs. It is widely used in applications involving low-voltage AC/DC, such as battery-powered electronic products and electrical circuit protection of solar photovoltaic systems.
