Electrical, Specialty Fuses

The 39018R2C5.5W fuse is a product of Littelfuse. As with all fuses, its purpose is to protect circuits from overloads and short-circuits in case of an electrical fault. This specific fuse is particularly useful in the automotive and electronics industries due to its low profile, high current rating and excellent durability.

The 39018R2C5.5W is a surface mount fuse with a rated voltage of 5.5V and a current rating of 2A. This fuse is designed for a variety of applications such as direct primary protection on PCBs, secondary protection on wire harnesses, and industrial protection on relays and solenoids. Additionally, it is UL and CSA approved and can be used for lighting, battery charging, and motor control systems.

The working principle of a fuse is simple. It contains a metal link which is connected to the main circuit. A wire is connected to the metal link that is insulated by an amorphous alloy. The electrical current passing through the metal link causes the wire to heat up due to resistance. When the current reaches a specific level, the wire melts, disconnecting the circuit and stopping the flow of electricity.

The 39018R2C5.5W fuse is also designed with a re-settable poly-switch that will re-set after the fault has been cleared and the current has dropped to a safe level. This will protect the circuit from further damage and help extend the life of the fuse. The fuse also includes a replaceable positive temperature coefficient (PTC) device. The PTC device is designed to detect faults in the circuit and delay the response of the fuse slightly, allowing it to absorb brief overloads in the circuit.

Overall, the 39018R2C5.5W fuse is an excellent choice for a wide range of applications. Its small size and high current rating make it suitable for use in automotive and electronics applications. Additionally, its re-settable poly-switch and PTC device are designed to protect the circuit and extend the life of the fuse.
