PTC Resettable Fuses, such as the 60R040XU, are polymeric positive temperature coefficient (PPTC) devices that can provide overcurrent protection for electronic applications. They are made from a conductive polymer material, such as polyethylene, which is coated with a metallic layer, such as aluminium. This gives the PTC fuse a much higher melting temperature than traditional fuses, making it well-suited for applications where the device may experience extended or repeated high currents, such as in motor control circuits.

The typical working principle of a PTC fuse is similar to that of a traditional fuse. When the device is subjected to an overcurrent, the resistance of the conductive polymer increases due to the effects of heat, which in turn causes a rise in temperature of the element. This rise in temperature has an exponential effect, so the resistance quickly increases until the heat generated by the PTC is equal to the amount of heat being dissipated into the circuit. The result is that the temperature and resistance of the fuse reaches a steady-state, and the circuit will be disconnected from the power source.

In the case of the 60R040XU, this is the “XU” standing for “Extra High Performance” and is a very robust PTC resettable fuse, with a good temperature coefficient and high temperature capability. With its high surge current capability and a low voltage drop, it is especially well-suited for applications in automotive, industrial and consumer electronics. It is also suitable for use with dual voltage systems, with the ability to self-sense a second voltage.

The 60R040XU has a wide operating voltage range, from 6-35V, and is able to withstand up to 40 A of continuous current. It has a high temperature rating of 105° C, and the fuse has a maximum impedance at 25° C of 1.2 Ohms. It also has a wide current range, with a breakdown current of 40A and a hold current of 4A, which makes it a suitable choice for most applications.

The 60R040XU is also designed to be self-resetting, meaning that once the power is turned off, the fault current will dissipate and the resistance of the polymer will return to normal, re-enabling the circuit. This eliminates the need for manual intervention and so saves time and cost in maintenance. The PTC fuse is also able to withstand exposure to short circuit events, making it a good choice for protecting high-performance circuits.

In summary, the 60R040XU is a robust PTC resettable fuse that is well-suited for a variety of applications including motor control circuits, automotive, industrial and consumer electronics circuits. Its ability to self-sense a second voltage, its wide operating voltage and current range, and its self-resetting ability make it a preferable choice for many applications.
