Inrush current limiters (ICL) are the electrical components used to mitigate large inrush currents, which is a sudden large current when an electric device is in the power supply process. MF72-004D13 is a type of Inrush Current Limiter (ICL). It is used to stop inrush current when less than 10A current is needed.The structure of MF72-004D13 consists of two parts. Firstly, the outer part consists of an upper and lower cover and an inner core. The upper and lower covers are larger, while the inner core is a small round disc. The inner core is covered by an insulating cover. Secondly, the lower part is a PTC thermal elements, which equipped with leads, and the other end is connected to an external transistor.The MF72-004D13 works similarly to a thermistor. When voltage is added to the circuit, it increases the temperature of the PTC thermal elements. These thermal elements react to the temperature increase and change the resistance of the circuit. This resistance limits the amount of current to be consumed, which reduces inrush current and improves the safety of the circuit.In the application field, MF72-004D13 is widely used to prevent current flow in electronic systems. Especially, it is commonly used in residential, commercial, and industrial applications, such as power supplies, lighting, and motors. It is also used in battery-powered devices, computers, electrical appliances, and drivers. It is the most suitable for circuits with high inrush current requirements.For the circuits with low inrush current requirements, the MF72-004D13 can also provide valuable benefits. It reduces the chance of the device over-heating and provides protection to the circuit from the chances of an electrical surge. In this case, the MF72-004D13 functions as an over-current protection device. It ensures that the current stays within the appropriate limits that the device requires.The working principle of the MF72-004D13 is simple. It utilizes the thermal property of the PTC thermal elements to limit the current. As the operating voltage is applied, this leads to an increase in the temperature of the PTC thermal elements. This increases the resistance of the circuit, which regulates the inrush current, preventing it from flow. This improves safety of the circuit and the device.The MF72-004D13, like other ICL’s, can be used for both AC and DC circuits, even for circuits with high inrush current requirements. It is a reliable component in industrial structures, and maintenance is also simple and inexpensive. In addition, it has a wide range of allowable voltage and current levels that can be used in different circuit applications. In summary, the MF72-004D13 is a type of Inrush Current Limiter (ICL). It is a reliable and low cost option for circuits requiring a low level of inrush current. It has many advantages like high current capacity, low heat dissipation, short lead time, and low shop volume cost, and it can be easily integrated into existing designs. The working principle of the use of a PTC thermal elements to reduce inrush current, ensures the safety of the circuit and the device. Thus, the MF72-004D13 is an ideal solution for inrush current protection requirements.
