Inrush Current Limiters (ICL)

Inrush current limiters (ICLs) are devices that provide inrush current protection to connected components in order to prevent currents or voltages from exceeding safe levels. In order to provide their function, an inrush current limiter must be able to accurately measure, limit, and clamp the incoming current or voltage that passes through it. One type of ICL is the B57236S0120M000.

B57236S0120M000 Application Field

The B57236S0120M000 ICL has a wide variety of applications. It is suitable for use in all kinds of electronic equipment, appliances, data processing systems, and communication systems. Furthermore, it can be used as surge absorber in power supplies, AC power sources, DC power sources, overvoltage protectors, and lighting systems.

B57236S0120M000 Working Principle

The working principle of the B57236S0120M000 ICL is based on a heavy-duty thermisitor. The thermistor has a temperature-dependent resistance so that at normal standby temperatures, the resistance is high and the current flow is low. In cases of inrush current, the thermistor’s resistance drops and allows a greater current flow, up to the maximum current rating of the device.The performance of the B57236S0120M000 lies in its ability to provide reliable and accurate inrush current protection. Its design includes many features that help to ensure a long service life and reliable current limiting performance. For example, the thermistor is housed in an epoxy-filled cavity, which helps to further reduce changes in resistance due to the ambient temperature. In addition, the B57236S0120M000 is designed with a metal oxide field-effect transistor (MOSFET) that is used to drive the thermistor. The MOSFET is able to provide precise and adjustable current limiting, which helps maximize the device’s performance in a variety of applications. This feature also helps to ensure a more reliable and consistent current limiting performance. Finally, the device includes a single-turn adjustment of the current limiting value, in order to provide the user with an easy and precise way to fine-tune the device to specific requirements. This feature helps to maximize performance and efficiency.

Conclusion

The B57236S0120M000 ICL is a reliable and accurate inrush current limiter that is suitable for a wide range of applications. It features a thermistor-based design, and a MOSFET-based driver, which help to ensure a reliable and consistent current limiting performance. Finally, it includes an adjustable current limiting value that allows the user to fine-tune the device for a wide variety of applications.
