Rfid Antennas Procurement Notes

Verify the specific ordering code against official TDK Electronics documentation to ensure correct variant selection. Confirm that the SMD package type and tape reel supply format align with manufacturing requirements. Cross-reference the 125 kHz operating frequency and 7 mH inductance values with system design specifications to guarantee functional compatibility.

Rfid Antennas Selection Notes

Select this component for applications requiring an AEC-Q200 qualified transponder coil. Ensure the 7.8 x 2.7 x 2.7 mm footprint fits the PCB layout constraints. Validate that the 125 kHz frequency range matches the reader system requirements. Consider the SMD mounting method for automated assembly processes.

Rfid Antennas Part Context

This part belongs to the B82450A series of transponder coils from TDK EPCOS. The manufacturer has integrated EPCOS passive components into its portfolio, though the EPCOS brand is being phased out for these products. This series supports automotive-grade RFID applications requiring standardized inductance and frequency characteristics.
