• Power supplies.

Working Principle

The MF72-005D9 ICL works on the principle of capacitive current limiting. It consists of a thin dielectric film and a specially designed electrode pattern to form a capacitor. The capacitor is connected between the input and output connections, creating an additional load on the power source when the load is connected. This acts to limit the current drawn by the load, preventing an inrush current surge.The MF72-005D9 ICL also has reverse voltage protection circuitry built into the circuit. This helps to protect the device from damage caused by reversed input voltage. It also has a temperature compensation circuit that helps to keep the limiting current constant over its wide temperature range.The MF72-005D9 ICL is capable of handling large current surges, with peak currents of up to 1.2A. This allows the device to handle the large power demands of many applications. It is also very compact, making it ideal for use in space-constrained applications.

Benefits

The MF72-005D9 provides several benefits when compared to other Inrush Current Limiter devices. It is highly reliable, with a low voltage drop across the device when current is passing through. This makes it ideal for use in high power applications. It also has a wide operating temperature range, making it suitable for use in a range of applications.The built-in temperature compensation ensures that the device will maintain its current limiting capability over its wide operating temperature range. This helps to ensure that the device can handle large current surges without damage. The device is also very compact, making it suitable for use in space-constrained applications.In summary, the MF72-005D9 is a highly reliable and versatile Inrush Current Limiter device. It is suitable for use in a wide range of applications, and has the capability to handle large current surges. Its compact size also makes it ideal for use in space-constrained applications.
