PTC Resettable Fuses refer to an electronic component whose purposes is to protect the connected devices in an electrical circuit from excessive current or overload. The 12VL175U is a specific type of resettable fuse that functions in a variety of different applications.

The 12VL175U comes in a variety of packages ranging from axial to radial leaded packages. It is available in 1.4W, 2W, and 3W ratings and is also designed to meet the requirements of numerous different industries, such as the automotive industry, medical industry, robotics industries, consumer electronics, and telecommunications.

A PTC fuse is different than a traditional fuse in that it is able to reset itself when the excess or overload current has been corrected. The 12VL175U is capable of automatically resetting itself after a certain amount of time, usually between 20 seconds and 2 minutes.

The PTC Resettable Fuse works on the principle of thermal conductivity. When the current flowing through the PTC fuse exceeds the rated current, the positive temperature coefficient (PTC) thermistor, which is a non-linear semiconductor resistor, begins to heat up. As the temperature of the thermal element increases, the resistance of the thermistor also increases. When the resistance increases to a point where the current is cut off, the overload is eliminated and the PTC fuse resets itself.

The 12VL175U can be used in a variety of different applications, such as electrical power tools, chargers, medical devices, and automotive electronics, to provide over-current protection. It is also able to provide protection against short-circuits, surges, and spikes.

The 12VL175U PTC Resettable Fuse has a number of features that make it a reliable protection solution. The fuse has an internal heat and winding insulation which protects against overloads and short-circuits, and a thermal break that prevents the fuse from burning out. The fuse is also designed with a reverse current protection feature that prevents the fuse from being damaged by reverse current.

The 12VL175U is a highly reliable, cost-effective, and specialised protection solution for a variety of different applications. It is designed to protect the connected devices or equipment from the risk of over-current and thermal runaway.
