PTC resettable fuses, also known as polymeric positive temperature coefficient (PPTC) fuses, are overcurrent protection devices designed to protect electronic circuits from short circuit and overload faults. The PTS181216V035 is a PTC resettable fuse designed for higher current and voltage applications. It has a rating of 18A, 12V, and 16V maximum operating voltages. It consists of a heat-sensitive polymer containing a silver bridge that fuses when excessive current passes through it.

The PTS181216V035 is used in a variety of electronic applications. It is often used in automotive electronics, such as power steering, power windows, and windshield wipers. It is also used in consumer electronics, such as power adapters, AC/DC adapters, and laptop chargers. The fuse can also be used in general industrial applications, such as control panels and other equipment that require high-current protection.

The working principle of the PTS181216V035 is fairly simple. When excessive current passes through the fuse, it begins to heat up due to its increased resistance. As the heat increases, the polymer material starts to expand, causing the silver bridge to fuse and effectively disconnect the current flow. The silver bridge then cools down, and the polymer material shrinks back to its original state, allowing the current to flow again.

The PTS181216V035 offers several advantages over traditional fuses. Unlike traditional fuses, PTC resettable fuses do not need to be replaced after each short circuit or overload, saving time and money in maintenance and replacement costs. In addition, the fuse eliminates the need for periodic visual inspections and testing of the fuse. They are also compact and easy to install.

The PTS181216V035 is a good choice for protecting circuits from short circuit and overload faults in a wide range of applications. Its resettable functionality makes it easy to use and maintain, while its high current and voltage ratings provide reliable protection for sensitive electronics.
