PTC Resettable Fuses

PTC resettable fuses are electronic components designed to protect low voltage circuits from short circuits and overloads. The TSM600-250-2 model is a low cost, low profile, fast-acting polymer PTC resettable fuse. It\'s designed for over current protection in a wide range of applications such as consumer electronics, telecommunication equipment, industrial and medical equipment, automotive electronics and embedded systems.

Application Field of TSM600-250-2

The TSM600-250-2 PTC resettable fuse is suitable for use in a wide range of electronic applications, such as in automotive electronics, computer motherboards, UPS power supplies, smart home appliances, home entertainment systems and consumer electronics. It can also be used in embedded systems, telecommunication equipment, and medical equipment for over-current protection.

Working Principle of TSM600-250-2

The TSM600-250-2 PTC resettable fuse operates on the same basic principle as a regular fuse, but is made of a polymer material that acts as a switch. When an over current or a short circuit occurs, the PTC quickly goes into an open circuit, cutting off the current flow. Once the fault condition is cleared, the device will automatically reset itself, restoring the current flow.

The TSM600-250-2 PTC resettable fuses utilizes a precisely controlled current-carrying element between two conducting plates. When a fault current passes through the element, it’s temperature rises quickly. This results in an increase in the resistance of the element, which prevents current from flowing. The fuse will remain in an open state until the current drops to a safe level.

Because of their high cycling capability, PTC resettable fuses are ideal for use in latest generation electronic circuits. They offer reliable protection and require minimal maintenance. In addition, they are very compact in size, making them suitable for use in even the most space-constrained applications.
