PTC Resettable Fuses are self-resetting polymeric Positive Temperature Coefficient (PTC) devices, providing long lasting, reliable and cost-effective over-current protection in many different applications. The PTC Resettable Fuses are available in a variety of sizes, currents and voltages for a wide range of applications. Some of the more common applications of PTC Resettable Fuses are in a variety of consumer electronics, chemical processing, power supplies, automotive, telecom, and medical equipment to name a few.

PTGL9SAS1R2K2B51A0 is a PTC Resettable Fuse that is designed for use in electrical and electronic circuits as a short circuit protection device. It can be used in a wide range of applications with a wide variety of load currents up to a maximum of 2.5A. It has a rated voltage of 32V DC, a maximum hold current of 0.1A and a maximum surge current of 5A. The device offers a rapid response with a fast trip time and a reset time of approximately 6 seconds.

PTC Resettable Fuses operate on the principle of a positive temperature coefficient of resistance. This means that as the temperature increases so does the resistance. When the device is exposed to an over-current that causes an increase in temperature, the resistance of the device increases such that the current is abruptly reduced. This abrupt reduction in current interrupts the circuit and limits the amount of heat which is produced by the circuit. When the over-current situation is removed, the device cools and the resistance of the device decreases such that the circuit is resumed.

In addition to providing over-current protection, PTC Resettable Fuses have the advantage of being self-resetting, meaning they reset themselves after the overload situation is removed. This eliminates the need to manually replace a fuse after administration of an overload. This can provide an additional level of safety and convenience to the user. These devices are also typically capable of providing a higher level of protection than that of a traditional fuse or circuit breaker, as they are capable of responding to a wide range of over-current situations from small to large.

The PTGL9SAS1R2K2B51A0 PTC Resettable Fuse is a reliable, fast acting device for providing over-current protection. This device is suited for a variety of applications including consumer electronics, communications equipment, instrumentation, telecom, medical equipment, and automotive devices. This device is designed to provide an effective over-current protection solution with a fast trip time and self-resetting capability to provide a high level of safety and convenience to the user.
