The SLF0302-221MTT Power Inductors 220uH ±20% 100mA SMD, manufactured by Sunltech are 3.5x3.0mm RoHS compliant electronic components. They feature a low frequency, medium current operation with a winding of 220uH ±20%100mA. They are particularly useful for applications which require high power density and stability, such as voltage regulators, switching power supplies, motor controllers, and DC/DC converters. The small size and low profile make for easy integration into high density circuits. They are reliable, robust, and provide superior heat resistance and EMI suppression. RoHS compliant and UL approved.
