PTC Resettable Fuses

PTC Resettable Fuses are widely used in circuit protection applications. PTGL12AS2R2K4B51B0 is one of the most common types of PTC Resettable Fuses. This type of fuse can effectively protect circuits from over-current and short-circuit conditions, and provide resetting capability in the event of a fault.

The application field of PTGL12AS2R2K4B51B0 is diverse, as it has the capability to be used in devices for telecom, HVAC, electrical containment, automotive, and consumer electronics. It can be used as protection for critical circuits in computers, servers, and home electronics. With its wide application field, this type of fuse is an attractive choice for engineers who need to protect their circuits.

PTGL12AS2R2K4B51B0 Resettable Fuse is thermally operated. The operation of the fuse is based on resistance. When the circuit has low current, the temperature of the fuse increases, resulting in a higher resistance. When the circuit current increases, the temperature of the fuse decreases, and the resistance drops. This mechanism is used in the fuse to detect whether the circuit is overloaded or not. When the circuit is overloaded, the temperature of the fuse increases, and the resistance increases, so the fuse \'trips\' and disconnects the circuit.

The resetting mechanism of the fuse is also based on the change in resistance. When the fuse trips, the increase in resistance causes the current to be cut off. This cause the temperature to drop, and the resistance to decrease. When the circuit is in a safe state, the resistance of the fuse will go back to its original value, and the circuit will be back in operation. This resettable capability of the fuse makes it an attractive choice for engineers, as it prevents the circuit from becoming permanently damaged.

PTGL12AS2R2K4B51B0 Resettable Fuses are reliable and efficient for use in circuit protection applications. It can effectively protect circuits from over-current and short-circuit conditions, and can reset itself when the fault has been cleared. With its diverse application field, this type of fuse is an attractive choice for engineers who need to protect their circuits.
