PTC Resettable Fuses are an important type of overcurrent protection devices, commonly used in a range of applications, including computers, telecommunications, consumer electronics and automotive products. They offer the advantage of a relatively low component cost compared to other higher-cost protection devices. The PTGL07BB220N0B52A0 PTC Resettable Fuse is no exception. This fuse offers an easy-to-integrate, cost-effective, overcurrent protection solution with excellent surge handling performance in applications up to 5A.

The PTGL07BB220N0B52A0 is a thermally operated fuse, which means that it has a unique trip mechanism that allows it to sense and trip at an overcurrent/overload, distorting the temperature of the device. At this point, the thermal fuse opens the circuit and protects the connected components from the dangerous and damaging effects of overcurrent/overload. The device will only reset when the overcurrent/overload condition subsides and the device returns to its normal operating temperature.

The PTGL07BB220N0B52A0 PTC Resettable Fuse is suitable for a variety of applications, such as LED circuitry, power supplies, power switching, and electronic equipment. It is ideal for applications that require a high level of protection, as it provides reliable and efficient protection against damaging voltages / currents such as short circuit, over-voltage, and over-current. In addition, the device is also able to survive high pulse current, transient over-voltages, and inrush current.

The PTGL07BB220N0B52A0 not only has excellent surge handling performance, but also ensures a more reliable over-temperature protection with its dual-Sensing design. It adopts a unique integrated over-temperature protection method, consisting of two independent Sensing components, namely Thermistor and Thermal Resistor. The Thermistor is responsible for sensing the ambient temperature and the Thermal Resistor for reporting the device temperature. In the event of a thermal power surge, the Thermistor reports the device temperature to the Thermal Resistor to ensure accurate over-temperature protection.

The PTGL07BB220N0B52A0 PTC Resettable Fuse has excellent surge handling performance with its dual-sensing design, making it an excellent choice for applications requiring reliable over-temperature protection. In addition, it is simple to integrate and has a low component cost, making it an economical and effective overcurrent protection solution.
