Introduction:

PTC Resettable Fuses are widely used across a variety of industries and applications. They are a type of fuse that, once it has tripped, can be reset without having to replace the fuse. This makes them an ideal choice for protecting sensitive electronic equipment from overcurrents. The 15LR260SU is a PTC resettable fuse that is commonly used in industrial and commerical applications. In this article, we will discuss the application field and working principle of this PTC Resettable Fuse.

Application Field:

The 15LR260SU has a wide range of applications in both industrial and commercial settings. It can be used in medical and military electronics for over-current protection, as well as other areas such as charging protection for rechargeable batteries. In consumer electronics, it can be used in the protection circuits of cell phone chargers, power banks, portable devices, and other consumer devices. In addition to having a wide range of applications, it is also easy to use and reliable, making it a popular choice in the industry.

Working Principle:

The working principle of the 15LR260SU is based on a positive temperature coefficient (PTC) device. A PTC device is a form of over-current protection that is based on thermal effects. When an over-current passes through the device, the temperature of the device increases, causing the resistance to increase. This helps to limit the amount of current that can pass through. When the temperature rises above a specific threshold, the 15LR260SU will trip, meaning it will suddenly rise in resistance and reduce the current. However, unlike regular fuses, it can be reset after it has tripped by allowing it to cool down. Once it cools down, the resistance will return to its normal value and it will be ready to use again. This allows the 15LR260SU to be used multiple times, which is why it is so popular in industrial and commercial applications.

Conclusion:

In conclusion, the 15LR260SU PTC Resettable Fuse is an ideal choice for over-current protection in a wide range of industrial and commercial applications. Its working principle is based on a Positive Temperature Coefficient device, which is why it can be reset after it has tripped. This makes it an easy-to-use and reliable choice for protecting sensitive electronic equipment.
