PTC Resettable Fuses: The MCL20 500100-A application field and working principle

PTC Resettable Fuses are a type of resettable, or self-resetting, fuses used in a wide variety of electronics applications. They are designed to protect circuits from overcurrent and short circuit conditions and are often found in computers, consumer electronics, medical systems, telecommunications, and other equipment. The MCL20 500100-A is a PTC Resettable Fuse with specific voltage and current ratings optimized for use in high-power applications.

The MCL20 500100-A PTC Resettable Fuse is designed to provide reliable overcurrent and short circuit protection without the need for manual resetting. It has a maximum voltage rating of 500V and a maximum current rating of 100A. The MCL20 fuse has a typical cold resistance of 20mOhms and a thermal response time of 500ms. A PTC Resettable Fuse can handle repetitive fast cycling and has an expected life of more than 10,000 cycles.

The MCL20 500100-A PTC Resettable Fuse has several key features that make it well suited for high-power and high-cycle applications. It has a low thermal coefficient, which ensures that the voltage drop across the fuse is maintained even during high-current surges. Additionally, the fuse has a high temperature coefficient, which allows the fuse to self-reset at high temperatures without the need for manual resetting. The fuse also includes an open-frame design, which helps minimize parasitic inductances and helps protect against false triggering.

The working principle of a PTC Resettable Fuse is relatively simple. When the fuse is exposed to a fault current, the current flowing through the fuse’s element will cause it to heat up. The temperature rise will cause the fuse element to expand, increasing its resistance. This increase in resistance will cause the current through the fuse element to decrease, eventually tripping the fuse and breaking the circuit. Once the fault current is removed, the fuse will cool down and the element will return to its normal state, resetting the fuse and allowing the circuit to be re-energized.

The MCL20 500100-A PTC Resettable Fuse is a reliable and cost-effective overcurrent and short circuit protection solution for high-power and high-cycle applications. It is designed for use in a wide variety of electronics applications such as computers, consumer electronics, medical systems, telecommunications, and more. By providing reliable short circuit and overcurrent protection, the MCL20 Resettable Fuse helps ensure the safety and reliability of electronic equipment.
