Inrush current limiters (ICL) are devices that limit instantaneous current caused by power surge when an electrical system is powered on. One type of ICL is model B57238S0709M000. This ICL has two main application fields and a particular working principle.

The first application field for model B57238S0709M000 is power-supply component protection in power-supply module designs. This ICL is designed with a low profile and is well suited to preventing large inrush currents in switch mode power supplies. Its construction eliminates the need for large snubber capacitors, allowing for even more compact designs. It also prevents excessive switching stress due to high inrush current when power is first applied.

Another application field for model B57238S0709M000 is surge suppression. This ICL can protect electronic equipment from voltage spikes caused by lightning strikes or other overvoltage events. Its construction effectively suppresses inrush current by using a small resistor and an air gap between its conducting plates, allowing it to act as an efficient surge suppressor.

The working principle of model B57238S0709M000 is centered around the air gap between its conducting plates. When power is applied to the ICL, the air gap starts to collapse and the voltage potential between the plates increases. But as the potential rises, the gap between the plates simultaneously decreases and the current is decreased. Once the current reaches a predetermined level, the gap will "snap" back and the ICL will no longer allow any further current to pass. This snap back phenomenon is called thermal tracking, and it limits the current until the system has totally stabilized.

Model B57238S0709M000 is a versatile ICL with two main application fields and a special working principle. It is designed to protect power-supply components from voltage surges and to function as an effective surge suppressor. The thermal tracking feature of this ICL makes it an ideal solution for preventing large inrush current when power is first applied.
