PTC resettable fuses are reliable, compact and programmable protection devices used in a wide variety of applications. These devices are typically used in consumer electronic and automotive applications where over current protection is needed. When a PTC resettable fuse is tripped, it stops the flow of current and remains open until the underlying fault condition is cleared. The 16R400GU application field and working principle are designed to provide a full range of current and temperature protection solutions.

The 16R400GU is a polymeric positive temperature coefficient (PPTC) fuse designed for use in a wide variety of applications. This device is constructed with a rated current of 4A; a rated voltage of 160V; and rated temperature symmetrical overload current of 240A at a temperature of 65°C. It can also be used in applications that require higher operating temperatures up to 105°C, and for higher current ratings such as 6A, 10A, and 20A.

The 16R400GU works on a very simple principle. When the current is greater than its rated current, the temperature of the element increases, causing it to expand and open the circuit. The PPTC element is designed to “self-heal” upon the removal of the over current. The element will cool and return to its original state, restoring the circuit.

The 16R400GU is a multipurpose device suitable for use in automotive, industrial and consumer electronics applications. It is ideal for use in applications that require over current protection and circuit differentiation. Some of the most common uses of this device include power circuits, protection of communication circuits, display circuits, and protection of home appliances. This device can also be used in automotive applications such as fuel pumps, power windows, and power sunroofs.

The 16R400GU offers significant advantages over traditional fuses, such as ease of installation, low cost, and compact size. This device also provides excellent electrical performance and thermal stability to ensure a reliable, resilient circuit protection solution. As a result, the 16R400GU is an ideal solution for a wide variety of applications, making it a vital component of many electronics designs.
