PTC Resettable Fuses

PTC resettable fuses, also known as polymeric positive temperature coefficient (PPTC) fuses, are a form of thermal protection used mainly to protect electronic circuits from accidents or surges. They have become popular in recent years due to their unique advantages over traditional fuses. Specifically, their ability to reset after a short circuit has occurred and their relative affordability in comparison to traditional fuses. The 1206L150PR PTC resettable fuse is a popular type of PTC resettable fuse and is used in a variety of applications.The 1206L150PR is part of a larger series of resettable fuses known as PTC polyswitch devices. It is a relatively small, rectangular-shaped component measuring at 12 by 4.95 millimeters. The device is designed to be non-inductive and is typically used to protect switching circuits. It has an operating voltage range of 6.5 to 25 Volts DC and can be used in a variety of applications, including telecommunications, avionics, and military equipment. The fuse uses a positive temperature coefficient (PTC) mechanism to protect against overload and short circuit conditions.When a significant overcurrent is applied, the thermistor in the PTC resettable fuse begins to heat up which causes the thermistor’s resistance to increase. This increases the voltage drop across the fuse and therefore limits the amount of current that can flow through it. If the current goes above the fuse’s current rating, the thermistor heats up more and its resistance increases further, resulting in more voltage being dropped across the fuse. In this way, the PTC resettable fuse provides current limitation and protects electronics from burning out due to an overcurrent.When the overcurrent has passed, the device cools down and its resistance drops again. In this way, the dynamic nature of the thermistor helps the fuse to reset itself automatically, without the need for human intervention. This is the major advantage of PTC resettable fuses over traditional fuses, which need to be replaced after an overload occurs.The 1206L150PR offers several other benefits in addition to its self-resetting capabilities. It has a relatively low self-resetting time of less than 1 second, which allows for faster protection. The device is also RoHS compliant, making it suitable for use in environmentally sensitive applications. Additionally, the fuse has a high interrupting capacity for its size and can handle fault currents of up to 10,000 amps.Overall, the 1206L150PR PTC resettable fuse is a great choice for a wide range of applications which require reliable and rapid protection from overcurrent and short circuits. Its small size, low self-resetting time, and high interrupt capacity make it a great fit for use in a variety of electronics and computer applications.
