Fixed Inductors Procurement Notes

Verify the exact part number against official TAI-TECH documentation to ensure compatibility with circuit requirements. Confirm that the unshielded configuration aligns with electromagnetic interference constraints in the target application. Cross-reference electrical parameters such as saturation current and thermal resistance with system specifications before finalizing procurement decisions.

Fixed Inductors Selection Notes

Select this component when a nonstandard form factor is required for space-constrained designs. The 1.5 µH value suits moderate frequency switching applications. Ensure the PCB layout accounts for the unshielded nature of the inductor to prevent magnetic coupling issues with nearby sensitive components.
