PTC Resettable Fuses, or Polymer Positive Temperature Coefficient Fuses, are a type of electronic fuse that is designed to be power cycle-able meaning they act as a safety device for power and thermal sensing. The RXEF010-2 is a specific type of PTC Resettable fuse appealing to a wide variety of applications.

PTC Resettable Fuses are devices that are designed to detect a potential overload and disconnect but then reset itself and restore the current circuit when the excessive current is removed. This type of circuit protection device offers a more reliable alternative to the other types of circuit protection methods.

The RXEF010-2 is a single channel, 0.1A, PTC resettable fuse with an operating temperature range of -40°C to 85°C. It is especially suited for low voltage/current applications such as white goods, consumer electronics, hand-held devices, and personal computers. The device features an extended life time and a reliable fuse action due to its zero-power delay time and reset time for safe operation.

The working principle of the RXEF010-2 is based on the time-temperature dependence of a PTC material. The RXEF010-2 device activates when a current surge occurs and it quickly clamps the excessive current. The device then putrs when the surge current is over. The PTC material inside the fuse is given time to cool off before the device can reset itself. Through this process of thermal heat dissipation, the device will reset upon cooling down, eliminating the need to replace the fuse after every overcurrent event.

The use of a PTC Resettable Fuse such as the RXEF010-2 also has protection against critical temperature rise due to their thermal current limitation. When compared to other technologies such as fuses, breakers and capacitors, the PTC Resettable Fuse is more reliable and efficient due to its sophisticated temperature management. The device is designed to function normally and will not blow constantly due to temperature rise, making it suitable for applications where over temperature occuring due to inadequate ventilation may be an issue.

In summary, the RXEF010-2 is a PTC Resettable Fuse designed for low voltage/current applications such as white goods, consumer electronics, hand-held devices, and personal computers. It is a reliable fuse that utilizes a time-temperature dependence of a PTC material in a safe manner. The device is designed to provide reliable fuse action and protect against critical temperature rise. Therefore, the RXEF010-2 is the perfect solution for applications where over current and temperature are a concern.
