Introduction to PTC Resettable Fuses

PTC resettable fuses, otherwise known as polymeric positive temperature coefficient resettable fuses, are special types of fuses that restore their original state when exposed to a certain amount of current. These devices are widely used in a number of fields, including consumer electronics, power supplies, medical equipment, and industrial applications.

YQS8123 Application Field and Working Principle

The YQS8123 is a UL-certified PTC resettable fuse developed by Hicoresmart Technology CO, Ltd. It is widely used in electronics and power supply application areas, such as LED lighting, automotive electronics, and other control systems.The YQS8123 is a simple, one-time device, containing a small circuit board and a thermal element inside. When an overcurrent situation takes place, the internal temperature rises and the fuse trips, interrupting the current flow. Once the issue is resolved and the temperature drops below a certain point, the fuse automatically restores its original state and the current will begin to flow again. The rated current is 6A, which signifies the maximum current that the fuse can handle without tripping.The YQS8123 has an extremely low internal resistance, meaning that it has no impact on the system’s voltage. Additionally, the device features a ceramic casing for increased durability and resistance to shock and vibration.

Conclusion

The YQS8123 is a UL-certified PTC resettable fuse developed by Hicoresmart Technology CO, Ltd. It is widely used in a variety of power supply and electronics applications, including LED lighting, automotive electronics, and other control systems. The device has an extremely low internal resistance, and features a ceramic casing for increased durability and resistance to shock and vibration. Additionally, it is able to automatically restore its original state when the temperature drops below a certain point.
