PTC Resettable Fuses are widely used for various applications. The PTS181233V110 is a particularly popular type featured with high power rating, high temperature range, low current limit, and wide working temperature.

According to its specifications, the operating and storage temperature of the PTS181233V110 ranges from -55°C to 125°C. Meanwhile, its maximum power rating is 12V and 330mA. In addition, its tripping point is 127–143°C. All these features make this type of PTC suitable for use in automotive, consumer electronics, LED lighting, and industrial device applications.

The working principle of the PTC Resettable Fuses is simple but effective. The fuses are constructed with a ceramic body filled with thermally conductive particles. A PTC heating element, usually containing silver, is embedded inside the ceramic body. When the current goes beyond the allowed rating, the temperature of the element increases, which triggers a rapid increase in resistance and cuts off the current.

Once the heating element is cooled down, it returns to its initial low-resistance, low-temperature state and the fuse is reset, which is why this type of fuse is also called "self-resetting fuse". The fuse is very reliable and highly resistant to damage, providing protection against overloads, short circuits, and overheating.

The PTS181233V110 is a reliable and cost-effective PTC Resettable Fuse designed to be used in a number of critical applications. It is robust and suited for long-term use in difficult environments due to its high temperature range. The fuse also allows quick and easy replacement without the need for soldering.
