PTC resettable fuses are one type of electrical product in the field of connecting, protecting, controlling and transforming electric systems. It is widely used in consumer electronic equipment as a form of over-current protection. The PTGL14AR100M6B72B0 is a PTC resettable fuse manufactured by Taiyo Yuden. It has a current rating of 100 mA and is ideal for low-frequency distributed power supply applications such as LED lighting.

The main function of PTGL14AR100M6B72B0 PTC resettable fuse is to help protect electronic products against over-current, transient surge, and short-circuit currents. When the current exceeds the rated value, it instantly generates heat from the resistance effect and melts the internal lead, so that it can stop the abnormal current from flowing further and protect the safety of downstream components. After the current is reset to the normal range, the fuse element can recover its conduction state automatically and the circuit can be resumed.

The PTGL14AR100M6B72B0 PTC resettable fuse has two pins for electrical connection, which can be easily and quickly soldered to the printed circuit board and act as a switch in the circuit. It is often used to protect sensitive electronic components, such as processors, memory modules, and other integrated circuits, from damage caused by over-current and excessive current flow.

PTC resettable fuses, including the PTGL14AR100M6B72B0, have a low loss design with fast response and good heat dissipation efficiency, so they are very reliable and stable in their operation. Additionally, they offer excellent electrical parameters in terms of working temperature, surge strength, and surge recovery rate. They can also withstand high power surge or current, which help ensure reliable current delivery in the electrical system.

In addition to the benefits of providing reliable over-current protection, the PTGL14AR100M6B72B0 PTC resettable fuse also offers great flexibility for applications such as LED lighting, distributed power supply, healthcare, and industrial automation. Due to its small size and two pins, it can be easily placed on the printed circuit board without taking up too much space. Its low temperature coefficient and low internal resistance also make it ideal for low frequency distributed power supply applications.

The working principle of the PTGL14AR100M6B72B0 PTC resettable fuse is simple. When the current exceeds the rated value, the internal resistance of the fuse element increases quickly, which causes heat and melts the lead inside the fuse. Thus, it interrupts the current flow and provides protection to the downstream components. After the current returns to the normal range, the heating of the fuse element stops and the lead will restore its original state and recover the conductivity. This will reset the fuse and reload the circuit.

In conclusion, the PTGL14AR100M6B72B0 PTC resettable fuse is reliable and stable, which makes it an excellent choice for low frequency distributed power supply applications such as LED lighting. It provides excellent electrical parameters and offers great flexibility in applications. With its simple working principle of detecting over-current and resetting after the current is returned to the normal range, it helps protect sensitive electronic components in the circuit from damage caused by excessive current.
