PTC Resettable Fuses come in a variety of sizes and shapes, with each designed to protect specific components and areas of a circuit from overloads and short circuits. Certain models are designed to protect against larger currents, while others are intended for more sensitive areas.

The 250R120-RAU fuse is a thermally protected, low voltage, current limiting PTC resettable fuse from Embedded Safety. This fuse has a wide application area, with particularly impressive performance in automotive chargers, battery packs, audio equipment, and communication products. With a range of current ratings up to 20A, it is suitable for both low current and high current applications.

The 250R120-RAU provides protection for its application by limiting the amount of current flowing through the circuit. When the current passing through the fuse exceeds the fuse\'s rating, the fuse thermally trips and interrupts the current flow in the circuit. Once the current passes below the fuse\'s rating, the fuse will be reset and the current flow in the circuit will be allowed to continue.

The 250R120-RAU can also monitor the temperature of the circuit in order to ensure that it does not exceed certain limits. This is done using a NTC (negative temperature coefficient) thermistor, which changes its electrical resistance depending on the temperature. When the temperature exceeds a particular limit, the thermistor will be activated and the fuse will trip. This ensures that the circuit will not become over heated and potentially cause damage.

The 250R120-RAU can be used in a variety of applications due to its wide range of current ratings. Low current applications include USB chargers, USB Hubs, and mobile device charging. High current applications include Battery Packs, Automotive Chargers and Communication Equipment.

The advantages of using a 250R120-RAU PTC Resettable Fuse are that it provides reliable and efficient protection for the various components of a circuit. Furthermore, it is simple to install and provides a low profile form factor. Finally, it is designed to be reset easily if the current does exceed the fuse\'s rating.
