Inrush Current Limiters (ICL)

MS22 10008-B is a specialized inrush current limiting device used to protect sensitive electrical components. It is designed to protect and control the inrush current associated with switching input power sources, such as AC/DC adapters, voltage regulators, and direct input regulators.

Working Principle

MS22 10008-B works by sensing the voltage of the line when the supply is switched on, triggering its internal circuit. When the voltage reaches a given level, it then limits the current from exceeding the set level and dissipates it (the unwanted current) in the form of heat. This quickly decreases the input voltage and restricts the maximum current that can be drawn from the line. This inrush current limit (IC) can be adjusted from a range of 5 to 160V and is delivered in a standard 16-pin DIP package.

Application Field

MS22 10008-B is used in applications such as automotive power supplies, industrial power supplies, AC/DC converters, UPS systems, and microwave ovens. Its inrush current protection is beneficial to many applications as it helps protect the electronics when power is initially switched on. For example, automotive power supplies require the device to limit the high inrush current when the device is switched on which can decrease the power supply component lifetime.MS22 10008-B is also used in many industrial applications such as industrial motor control and power conversion. Many industrial control systems have long wire runs and poor transient voltage suppression that can cause significant current transients. In these situations the use of an MS22 10008-B is beneficial as it can limit the inrush current, protecting the sensitive electronics from potential over-current damage.Finally, MS22 10008-B is used in some consumer applications such as wireless OEMs, set-top boxes, and network switches. In these applications, MS22 10008-B can provide transient immunity over the entire power supply line and help increase system reliability and performance.Inrush current limiters are an important piece of technology to help protect and improve performance of sensitive electrical components. MS22 10008-B is ideal for many applications that require reliable inrush current protection and regulation due to its wide range of adjustable settings and small form factor.
