The B57211P0xxxM3x1 series from EPCOS are radial leaded NTC inrush current limiters (ICLs). These NTC thermistors can be used as inrush current limiters to suppress high inrush current. The high currents in the circuits are caused by low impedance of smoothing capacitors or coils which produce short circuits when the device is switched on. B57211P0xxxM3x1 series ICLs are commonly used in peripheral communication equipment such as switch mode power supplies.
