HF70ACC201209-TD25

Chip Ferrite Bead Overview

The TDK HF70ACC201209-TD25 is a surface-mount ferrite bead designed for signal line noise suppression. It features an impedance of 10 ohms at a test frequency of 100 MHz and supports a maximum DC current of 1.5 A. The component has a maximum DC resistance of 30 mOhms and a tolerance of 25%. It operates within a temperature range of -40°C to +125°C. The device is housed in an 0805 (2012 Metric) package with dimensions of 2.0 mm length, 1.2 mm width, and 0.9 mm height. It holds AEC-Q200 qualification.

Chip Ferrite Bead Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Compact 0805 surface-mount footprint for space-constrained designs
• Low DC resistance to minimize signal loss in power lines

Chip Ferrite Bead Applications

• Automotive electronic signal line filtering
• Noise suppression in high-speed digital circuits
• EMI reduction in compact consumer electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix TD25 against official TDK documentation to confirm reel specifications and tape-and-reel parameters. Ensure the procurement channel provides valid traceability for AEC-Q200 certified components. Confirm RoHS compliance status through the manufacturer's latest declaration before integration into production.

Chip Ferrite Bead Selection Notes

Select this component when a low-impedance path is required for signals carrying up to 1.5 A. The 10-ohm impedance at 100 MHz targets high-frequency noise without significant attenuation of the primary signal. The small 0805 package allows for dense PCB layouts compared to larger ferrite beads.

Chip Ferrite Bead Part Context

This part belongs to the TDK HF-ACB/ACC series of ferrite chip beads. These components are engineered for EMI suppression in both general industrial and automotive applications. The ACC series specifically denotes automotive-grade reliability, ensuring performance stability under varying thermal conditions typical in vehicle environments.

Chip Ferrite Bead Replacement Considerations

Cross-reference with MMZ1608R150ATD25 for potential functional equivalents in similar packages. Verify that any substitute maintains the 1.5 A current rating and 10-ohm impedance profile to ensure circuit compatibility.
