1812L150PRT

PTC resettable fuses are protective devices designed to protect circuits and components from overcurrent faults.

The 1812L150PRT resettable fuse is a compact fuse designed for applications in various industries. It features current ratings of 150mA maximum, voltage ratings of 35V DC minimum, and is housed in a 0805 SMD package. The device is designed to respond to overloads or short circuits, and is intended to protect circuitry from damage due to excess current.

The 1812L150PRT is designed to be installed on a printed circuit board (PCB). With a low profile design, the device provides an easy mounting option. The device can be used to protect motor drivers, power supplies, actuator drivers, and other control electrical systems. The resettable fuse can be used in both commercial and industrial applications.

The 1812L150PRT resettable fuse utilizes a Positive Temperature Coefficient (PTC) technology. The device consists of a small ceramic disk with a section of resistor material deposited on its surface. When the device is placed in an electric circuit, current will flow through the resistor material, generating heat. As the current increases, the temperature of the resistor material will increase, and the resistance of the material will increase proportionally. Once the current reaches the rated value of the device, the temperature will exceed the melting point of the resistor material, causing it to open the circuit. The device will return to its original state when the circuit cools down.

The PTC resettable fuse has several advantages over traditional fuses, such as being able to recover from an overload or short circuit without the need for manual replacement. Additionally, the device requires limited space and offers higher electrical ratings compared to conventional fuses.

In summary, the 1812L150PRT resettable fuse is designed for applications requiring protection from overcurrent faults or short circuits. The device utilizes PTC technology to open the circuit in the event of an overcurrent situation, and will automatically reset itself once the temperature cools down. The device is available in a low profile SMD package and can be used in both commercial and industrial applications.
