Fixed Inductors Procurement Notes

Verify the specific suffix codes against official TAI-TECH documentation to ensure correct tolerance and packaging specifications. Confirm that the 19 mΩ DC resistance and 8 A current ratings align with your circuit requirements before finalizing orders. Request updated datasheets directly from the manufacturer or authorized distributors to avoid discrepancies in technical parameters.

Fixed Inductors Selection Notes

Select this component when high current handling capability and compact shielding are required for power integrity. The 4.7 µH value suits intermediate filtering stages in broadband infrastructure. Ensure PCB footprint matches the 1004S package dimensions and verify thermal management capabilities for continuous 8 A operation in dense layouts.

Fixed Inductors Part Context

This inductor belongs to the TMPA series of laminated chip components produced by TAI-TECH, established in 1998. The company specializes in precision wire-wound and integrated electronic solutions. This specific model represents a standard shielded variant within their advanced electronics portfolio designed for robust industrial and communication applications.

Fixed Inductors Replacement Considerations

The TMPC1004H-4R7MG-D is a related variant offering higher current capacity (10 A) but different resistance characteristics. Verify compatibility if substituting, as package dimensions and electrical limits differ. No other direct cross-model substitutes are confirmed in public documentation.
