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.
