Inrush Current Limiters (ICL) are a specialized type of electronic device that can be used to limit large amounts of current from flowing through a circuit. The B57238S0160M000 is one such device which belongs to the KEMET family of ICLs. This ICL is specifically designed to provide inrush current limiting and overcurrent protection for low and medium power applications. Application FieldThe B57238S0160M000 is a versatile and robust ICL with a low on-resistance and a maximum working voltage of 310V. It is designed for use in a wide variety of applications including power supplies, motor control circuits, variable speed drive circuits, switch mode power supplies (SMPS), and battery chargers. The device is designed to provide quick and reliable protection against damaging inrush currents, thus preventing components from becoming damaged by too much current. Additionally, the device can also provide overcurrent protection by detecting and limiting sudden increases in current.Working PrincipleThe B57238S0160M000 works by sensing the inrush current and using a resistive element to reduce the current to a safe level. The device contains an integrated NTC thermistor, which acts as a resistor when exposed to a current. This thermistor is designed to reduce the current when the temperature continues to increase beyond a certain threshold. This current-dependent thermal protection helps to protect the device and other components from damage caused by large inrush currents.Additionally, the device also features overload and reverse polarity protection, ensuring it is safe to use in most applications. Reverse polarity protection prevents components from being damaged if the device has been incorrectly connected in a circuit. Overload protection helps to protect components from excessive current, preventing them from becoming damaged.The B57238S0160M000 is a reliable and versatile ICL that can be used in a variety of applications. It is designed to effectively limit large inrush currents, as well as providing overcurrent protection. Its reverse polarity and overload protection features provide additional safety for components, ensuring that they are not damaged by incorrect connections or overloading.
