MMZ1608SHE471ATD25

Overview

The MMZ1608SHE471ATD25 is a single-line ferrite chip bead from the TDK MMZ-HE series, designed for automotive applications. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 470 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 500 mA. It has a maximum DC resistance of 300 mOhms and a tolerance of 25%. Certified to AEC-Q200 standards, it operates within a temperature range of -55°C to +150°C.

Feature Summary

• High-temperature operation capability up to +150°C suitable for demanding environments
• Shielded construction to minimize electromagnetic interference coupling
• Automotive-grade reliability certified under AEC-Q200 standards

Applications

• Automotive signal line noise suppression
• High-temperature electronic circuit filtering
• EMI suppression in compact automotive modules

Procurement Notes

Verify the specific suffix TD25 against official TDK documentation to confirm packaging and tape specifications. Ensure the design accommodates the 0603 footprint and thermal requirements for high-temperature operation. Confirm AEC-Q200 certification status through manufacturer datasheets prior to integration into automotive systems.

Selection Notes

Select this component when shielded ferrite beads are required for high-temperature automotive signal lines. The 470 Ohm impedance at 100 MHz targets specific noise frequencies. The 500 mA current rating suits low-power signal circuits. Compare with standard MMZ series parts if lower temperature ratings are acceptable.

Part Context

This part belongs to the TDK MMZ-HE series, which specializes in high-temperature ferrite beads. It shares the 0603 form factor with other MMZ1608 variants but distinguishes itself through enhanced thermal performance and shielding characteristics. The series is tailored for automotive electronics requiring robust EMI suppression under extreme conditions.

Replacement Considerations

Check for direct substitutes within the MMZ1608 family with matching impedance and current ratings. Verify that alternative parts meet the same AEC-Q200 and high-temperature requirements.
