Additional Details

The SLF7045T series from TDK features a metallic magnetic material core. This provides excellent DC bias characteristics, meaning the inductance value remains relatively stable even under high DC current conditions. The "T" in the part number may refer to the terminal shape or packaging. Always check the datasheet for specific details such as the self-resonant frequency (SRF), which is important in high-frequency applications. The "PF" suffix indicates that the component is lead-free and RoHS compliant. It's typically used in buck and boost converter designs. Proper thermal design is crucial to ensure long-term reliability and prevent overheating. Consult the datasheet for thermal resistance specifications.
