MMZ1608S102ATD25

Overview

The TDK MMZ1608S102ATD25 is a single-line ferrite chip bead designed for signal line applications within the automotive sector. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.95 mm height. The component provides an impedance of 1 kOhms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 400 mA and exhibits a maximum DC resistance of 500 mOhms. The device operates reliably within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Designed specifically for signal line noise suppression
• Compact 0603 surface-mount form factor

Applications

• Automotive electronic circuits
• Signal line EMI suppression
• High-frequency noise filtering in vehicle systems

Procurement Notes

Verify the specific suffix TD25 against official TDK documentation to confirm packaging configuration and reel specifications. Ensure compatibility with standard SMT assembly processes for 0603 components. Cross-reference the AEC-Q200 certification status directly with manufacturer records to validate automotive grade requirements before integration into production designs.

Selection Notes

Select this component when signal integrity protection is required in space-constrained automotive environments. The 1 kOhm impedance at 100 MHz targets specific high-frequency interference profiles. The 400 mA current rating suits low-power signal lines rather than power distribution paths. Consider the 500 mOhms DCR impact on signal attenuation during circuit simulation.

Part Context

This part belongs to the TDK MMZ Auto series, which specializes in ferrite beads for automotive electronics. The MMZ1608 series utilizes multi-layer technology to provide effective electromagnetic interference suppression in compact packages suitable for modern printed circuit board layouts.

Replacement Considerations

Check for other MMZ1608 variants with matching 1 kOhm impedance and 400 mA ratings. Verify that any substitute maintains AEC-Q200 qualification and identical 0603 footprint dimensions for direct replacement.
