PTC Resettable Fuses
PTC resettable fuses have become a must-have part of many applications, as they help protect expensive electronic components against accidental overload, high current and short circuits. The 1812L260THDR is no exception and has become a sought-after PTC fuse due to its capability of resetting itself after a surge or short circuit occurred. This article will discuss the application fields and working principle of the 1812L260THDR. Application Fields
The 1812L260THDR is a high-performance PTC resettable fuse, which is mainly suitable for use in consumer electronics, IT/Telecom, industrial, medical and automotive applications. With its ability to automatically detect and reset after a short circuit happened, the 1812L260THDR has found its way in all kinds of electronic products, including laptop computers, Autonomous Vehicles (AVs) and other consumer and industrial applications. Working Principle
The 1812L260THDR fuse utilizes a thermistor polymer-based material with a gradually changing resistance with temperature. By this way, it can detect any excess current, causing the resistance to rapidly increase when the temperature rises. When the current in the circuit goes beyond the rated current, the thermistor will generate heat and therefore increase its resistance. This will cause a rapid temperature rise, which in turn will trigger the fuse to open and cut the power supply to the circuit. After the fuse has opened, the temperature can cool down and reset itself. Conclusion
The 1812L260THDR is an efficient PTC resettable fuse offering superior protection against overload, short circuit, and reversed polarity. With its ability to automatically detect and reset itself, it becomes a very reliable device for many applications. Despite the fact that the working principle is not fully understood by everyone, the usage of this PTC resettable fuse still provides a safe and reliable way to protect expensive electronic components.
