PTC Resettable Fuses are devices that limit the surge and inrush current in an electrical circuit to protect a power source. The PTGL12AS0R8K2B51A0 is a resettable fuse with excellent features and performance. This article will discuss the application field and working principle of this device.

Application Field:

The PTGL12AS0R8K2B51A0 Resettable Fuse is designed for use in safety circuits in portable devices such as laptops, tablets, and cell phones. It is also suitable for use in equipment such as HVAC system, heat pumps, and vending machines. Additionally, it can be used in automotive applications as well. This device is a very versatile performer and can be utilized in a variety of fields.

Working Principle:

The PTGL12AS0R8K2B51A0 Resettable Fuse works on the principle of thermal conduction. This device is composed of a positive temperature coefficient thermistor and a ceramic filled material. When an excessive or resistive current occurs in the electrical circuit, the heat generated by the current is absorbed by the device. This action causes the device to climb in temperature and eventually reach the peak temperature where the device will trip itself and open the circuit. The device will then cool down and reset itself allowing the current to flow freely again.

When the device is tripped, a visual indicator will activate and advise the user that trip has occurred and the circuit has been protected. When the current falls back to safe levels, the thermal element of the device will return to its original state and current will be allowed to flow freely.

The PTGL12AS0R8K2B51A0 Resettable Fuse provides effective protection from overcurrent in portable applications such as laptops, tablets, and cell phones. It has a vibrant selection of applications and its resetability makes it an excellent choice for safety circuits.
