PTC Resettable Fuses are widely used in a multitude of applications and protect against an endless list of things from toaster fires to automotive chips. They are used to protect circuits from overloads, short circuits, and other undesired conditions. The PTC Resettable Fuse, specifically the PTGL7SAS2R7K2B51A0, is an important component for many industrial applications. This article will discuss the application field and working principle of this particular fuse.

Application Field

The PTGL7SAS2R7K2B51A0 PTC Resettable Fuse is mainly used for devices that require high current load, such as motors, power converters, and inverters. It is also suitable for high efficiency applications, such as communications and lighting. This fuse is known to be highly reliable, so it is also used in medical and industrial equipment. In addition, the fuse is a good option for devices that require frequent switching, such as solar cells and batteries.

Working Principle

The fuse is designed to protect the devices against overload or short circuit. It utilizes a PTC resistor, made from a special ceramic material, which has both positive temperature coefficient (PTC) and self-resetting characteristics. During normal operation, the PTC Resettable Fuse allows electric current to flow through its terminals. However, if an overcurrent or short circuit occurs, the PTC resistor heats up and increases its resistance. This will restrict the current flow and protect against damage to the device. At the same time, the fuse will automatically reset once the overload or short circuit is removed. This makes it extremely useful for industrial applications, as it prevents the need to manually reset the fuse after every short circuit.

In conclusion, the PTGL7SAS2R7K2B51A0 PTC Resettable Fuse is an important component in many different types of industrial equipment. It has a wide range of applications and has an efficient working principle that allows it to protect devices against overloads and short circuits. Additionally, its self-resetting feature makes it extremely convenient to use for frequent switching. This makes the PTC Resettable Fuse a cost-effective and reliable part for industrial applications.
