PTC Resettable Fuses

PTC resettable fuses are miniature devices built to protect electrical circuits from overloads and short-circuiting. Unlike traditional fuses, PTC resettable fuses can be reset automatically after a fault has been corrected, eliminating the need to replace the fuse each time it trips. This feature leads to increased reliability and improved safety in circuit protection applications.The 0603L150SLYR resettable fuse is a miniature, ceramic-encapsulated, PTC resettable fuse designed for use in low-voltage circuit protection applications. It is designed to be used in switch-mode power supplies and other electronic equipment where the ambient temperature is between -55°C and +125°C. The 0603L150SLYR has a trip current of 150 mA and a hold current of 20 mA. It is designed for applications in which an overcurrent must be detected and the load must be disconnected from the overload current without the use of a circuit-breaker or fuse.The working principle of a 0603L150SLYR PTC resettable fuse is based on the positive temperature coefficient (PTC) effect. When a current flow through the PTC resettable fuse is greater than the specified trip current, the device begins to heat up. As the device heats up, its resistance increases, which in turn causes the current to be further reduced, eventually leading to total device failure. When the fault condition is removed, the device will automatically reset itself back to its original low impedance condition, allowing for normal operation of the circuit. This automatic resetting feature is what makes PTC resettable fuses so unique and desirable in many applications. The 0603L150SLYR resettable fuse is most commonly used in low-voltage circuit protection applications, such as AC adapters, PC motherboards, and other consumer electronics. It can also be used in industrial control systems, such as motor drives, medical equipment, or LED lighting systems.In summary, the 0603L150SLYR PTC resettable fuse is a miniature fuse designed for low-voltage circuit protection applications. It has a trip current of 150 mA and a hold current of 20 mA and is designed for use in environments with a temperature range of -55°C to +125°C. The working principle of the fuse is based on the positive temperature coefficient (PTC) effect, where an overcurrent will cause the device to heat up and its resistance to increase, leading to device failure. Once the fault condition has been removed, the device will automatically reset itself, eliminating the need for manual resetting or replacing the fuse each time it trips. The 0603L150SLYR resettable fuse is a reliable and easy-to-use solution for circuit protection in a wide range of applications.
