Additional Details

The SLF10145T series features a metallic magnetic material core, offering superior DC bias characteristics compared to ferrite cores. This allows the inductor to maintain its inductance value even under high current conditions. The inductor is RoHS compliant and halogen-free, making it environmentally friendly. The "PPF" suffix in the part number indicates that it is suitable for lead-free soldering. The self-resonant frequency (SRF) is an important parameter to consider for high-frequency applications; consult the datasheet for the SRF of this specific inductor. This inductor is often used in buck and boost converter topologies.
