The SPI-T series high-current unshielded SMD power inductor is designed for DC-DC converter applications. Multiple package sizes are available (0402T, 0802T, 0804T, 0810T, 1109T, 1306T), suitable for different power level requirements. The product offers low DCR and high current capacity, effectively reducing power loss and improving conversion efficiency. The unshielded open structure offers cost advantage as its core competitiveness. It is suitable for applications with less strict EMI requirements. Tape and reel packaging supports automated placement and is compatible with reflow soldering. It is widely used in DC-DC converters for mobile phones, PDAs, MP3 players, digital cameras/camcorders, hard disk drives, and portable devices.

Q: What package sizes are available for the SPI-T series?
A: The SPI-T series offers six package sizes: 0402T, 0802T, 0804T, 0810T, 1109T, and 1306T, covering applications from compact to high-power. For specific dimensions, please refer to the product datasheet or contact our sales team.
Q: What is the significance of low DCR?
A: Low DCR means less power loss (I²R loss) when current passes through the winding. This helps improve overall DC-DC converter efficiency, reduce temperature rise, and extend battery life in portable devices.
Q: Does this product support reflow soldering?
A: Yes. The SPI-T series SMD inductors are compatible with reflow soldering. Tape and reel packaging is suitable for automated placement lines. For the specific reflow temperature profile, please refer to the product datasheet.
