Rfid Antennas Procurement Notes

Verify the exact ordering code suffix to confirm the specific inductance value and sensitivity rating required for your design. Ensure compatibility with existing PCB layouts and mounting requirements. Confirm that the component meets all necessary automotive qualification standards for your specific application environment.

Rfid Antennas Selection Notes

Select this component when space constraints are critical due to its compact dimensions. Consider the operating frequency and sensitivity requirements for the target PEPS system. Evaluate the need for multi-axis configuration by combining it with other directional coils if omnidirectional coverage is required.

Rfid Antennas Part Context

This part belongs to the EPCOS B82451L series of Z-axis transponder coils. The series includes seven variants covering inductances from 1.0 mH to 10 mH. These components are designed to work in conjunction with B82450A series X and Y axis coils to provide flexible design solutions for automotive access systems.

Rfid Antennas Replacement Considerations

Check for updated TDK ordering codes as the EPCOS brand has been discontinued for passive components. Verify dimensional and electrical equivalence before substitution.
