PTC Resettable Fuses are a specialized type of metal-oxide-based polymeric positive temperature coefficient (PPTC). The metal-oxide in the PTC Resettable Fuses increases in resistance as the temperature rises. PTC Resettable Fuses are typically used as overcurrent protection devices in consumer electronics, automotive and industrial applications.

The YS5631 is a Polymer Positive Temperature Coefficient (PPTC) resettable device designed to protect sensitive electronic equipment from over-current situations. It is a UL recognized component designed for over-current protection of circuit boards, components, wires, and cables.

The YS5631 is available in several amperage ratings, ranging from 2A-25A. Its main functions are to provide over-current protection and to act as a safety valve or shutoff in the event of an over-current situation.

The YS5631 includes a polymeric positive temperature coefficient (PPTC), which provides two main functions. The first function is that it will provide over-current protection by immediately tripping when the rated amperage is exceeded.

The second function is that the PPTC will automatically reset when the overcurrent is removed. This is done by relying on the fact that PPTC resistors increase their conductive path when their temperature increases. As the over-current is removed, the PPTC will cool off and will reset to its original conductive state, allowing the system to resume its normal operations.

The YS5631\'s wide operating temperature range, ranging from -40°C to 150°C, makes it suitable for a variety of applications including consumer electronics, automotive and industrial systems. Additionally, the YS5631 has a low profile that makes it suitable for space-limited designs. The YS5631 is also able to withstand over-currents up to 400amps for 10ms in a 10mm package.

The YS5631 is most commonly used in entertainment, home, and commercial electronic products to protect against the possibility of catastrophic failure that could result from overcurrents or overloads. It can also be used as a circuit breaker in applications where it is desired to be able to reset the system without having to replace any components, like when power is restored after a power surge.

In automotive applications, the YS5631 is used to provide continuous protection against overcurrents and help prevent motor and other components from being damaged due to an overcurrent situation. The YS5631 is also used to protect batteries from overcharging or discharging and can provide protection against excessive current in solar arrays.

The YS5631 is a reliable, self-resetting fuse that can provide extra protection and reduce turnaround and maintenance costs over the life of the system. It is highly durable and can withstand vibrations, shocks, and high temperatures, making it suitable for a wide range of applications. With its low-profile, compact design, the YS5631 can provide a great solution to overcurrent protection in a wide variety of applications.
