PTC Resettable Fuses are a type of fuse that are designed to protect electronic circuits from their current overload. They are used extensively in industrial applications and offer many advantages over regular fuses.

The 0805L075SLYR is a common example of a PTC Resettable Fuse. It is a two-terminal leaded chip that is very small in size at just 8mm x 5mm. It is designed for compatibility with standard automated insertion processes. The fuse is designed to switch off and reset automatically when the current overload reaches a certain level, providing circuit protection from current-related faults.

The working principle of the 0805L075SLYR, and other PTC resettable fuses, is based on the kinetic theory of thermal runaway. This theory states that when an electrical current is subjected to an increase in ambient temperature, the current-carrying capacity of the fuse will increase as well. In the case of the 0805L075SLYR, this increase in current carries capacity is coupled with an increase in the fuse resistance. When the current overload reaches a certain level, the resistance of the fuse will increase even further, switching off the circuit and causing the fuse to reset. When the current overload is reduced, the resistance of the fuse drops back down, again resetting it and allowing the circuit to be reactivated.

The 0805L075SLYR has a wide variety of applications. These include applications in consumer electronics, automotive electronics, industrial control circuits, PC peripheral devices, solar cell protection, optical data transceiver protection, printer protection, and LED lighting systems. Its small size and thermal runaway properties make it ideally suited for these kinds of applications. It is also a great choice for applications that require high-density mounting, since its small size allows for easy setup on densely-populated PCBs.

In conclusion, the 0805L075SLYR is an example of a PTC Resettable Fuse that is designed to protect electronic circuits from current overloads. It is designed for compatibility with automated insertion processes and has a wide range of applications in many different industries. Its working principle is based on the kinetic theory of thermal runaway, and its small size allows for easy setup on densely-populated PCBs. With its many advantages, the 0805L075SLYR is an ideal choice for many kinds of current protection applications.
