The SLF12555T-220M2R3-PF with Fixed Inductors SMD 22uH 2.3amps manufactured by TDK is an electronic component from TDK, a manufacturer of industrial, commercial, and consumer technology components. It is a surface-mountable inductor that can provide up to 2.3 amp current at a frequency of 220 MHz. It supports a wide range of operating temperatures, from -55 to +125 °C, and is made of a high-purity magnetic microwire coil that provides a high level of inductance. The package size of this component is small, with leads of 2.2 mm width, making it ideal for applications where space constraints are a concern. It is also RoHS-compliant, and meets the requirements of UL 94V-0.
