Additional Details

The SLF7045T series features a metallic magnetic material core, ensuring excellent DC bias characteristics. This means the inductor maintains its inductance value even when subjected to high DC currents. The "T" in the part number may refer to the terminal configuration. Always refer to the official TDK datasheet for complete specifications, including self-resonant frequency (SRF), which is essential for high-frequency circuit designs. The inductor is RoHS compliant, making it environmentally friendly. It is commonly used in buck, boost, and buck-boost converter topologies. Proper thermal considerations should be taken to ensure optimal performance and long-term reliability.
