PTC Resettable Fuses are an advanced type of fuse that gives more protection to electronics. They are usually placed in circuits to protect them from overloading and short circuiting. This type of fuse, also known as a ‘Polymeric Positive Temperature Coefficients Resettable Fuses’, works by having a special sensing element which detects when the current is too high and will cut off the circuit. The fuse resets itself after the current is dropped and the element cools down. LVR008K is a type of PTC resettable fuse that is popular with electronics manufacturers. It is a small size surface mount fuse that is designed for high density PCB assembly. It is available in high-current versions with current ratings from 250mA to 4.0A. The LVR008K fuse has a fast acting response times and can sense electrical faults quickly. It has a high breaking capacity to protect the circuit from high current inrush and over current. It also has a low temperature coefficient, meaning it will not become less sensitive over time. The working principle of the LVR008K is based on a sensing element that is temperature-sensitive. This element will detect when the current is too high and will then start to heat up. When it reaches a set temperature, the contact will open, and the current will be cut off. In order to reset the fuse, the temperature must come down and the contact must cool before it will close again. The LVR008K can be used in a variety of applications such as automotive, consumer electronics, telecoms equipment, consumer goods and lighting equipment. It is also suitable for use with AC and DC circuits. As well as providing overcurrent protection, it can also provide protection against voltage transients and surges. Overall, the LVR008K is a highly robust and reliable fuse for protecting electronics from overcurrent and short circuit faults. It provides cost-effective protection for a variety of applications and is one of the most popular resettable fuses available.
