PTC Resettable Fuses are used to provide overcurrent or overvoltage protection with their automatic reset capability. The 1206L200PR is a one-time programmable resettable fuse manufactured by The LittleFuse Corporation. It is designed for use in telecommunication devices, automotive, consumer electronics, industrial, and medical applications, and is UL, CSA, and TUV approved. The device is a positive temperature coefficient thermistor (PPTC) device.

The 1206L200PR consists of a resistive element formed from a coated semiconductor material and spring-like terminations. When the device reaches a predetermined temperature, the resistive element goes into an “open” state so as to interrupt the flow of current. As the device cools down, the resistive element contracts and returns to its low resistance “closed” state. This allows it to be used for overcurrent and overvoltage protection because it interrupts the current flow at high temperatures, and then automatically resets when it cools. The device can be triggered multiple times but it eventually “opens” and needs to be replaced with a new one.

The 1206L200PR features a low resistance (less than 0.60 ohms) when in its “closed” state, and a high resistance (over 200K ohms) when in its “open” state. It also has a rated voltage of 200VAC and a rated current of 4.7A. The device has a fast response time (less than 5 seconds) and low trip and reset temperatures of 180°C and 160°C respectively. It also has an operating temperature range of -40°C to 85°C and an electrical endurance of 6000 cycles.

The 1206L200PR has a wide range of applications due to its low resistance and high voltage/current ratings. It can be used for overcurrent/overvoltage protection in telecommunication devices, automotive, consumer electronics, industrial, and medical applications. It can also be used for control circuits in home appliances like ovens and refrigerators, as well as motor protection in heating systems. Additionally, the 1206L200PR can be used to provide protection against transient current surges, such as those caused by lightning strikes or surges on the grid.

The 1206L200PR is a one-time programmable resettable fuse that is easy to integrate into different systems. It offers a great combination of overcurrent and overvoltage protection capabilities, with a low resistance and high voltage/current ratings, and an operating temperature range of -40°C to 85°C. The device can be used for various applications including control circuits in home appliances, motor protection in heating systems, and for transient current surges. Its fast response time and UL, CSA, and TUV approvals make it an ideal choice for different applications.
