MMZ1608S400ATA00

Overview

The MMZ1608S400ATA00 is a single-line ferrite chip bead from the TDK MMZ series, designed for surface-mount applications in the 0603 (1608 metric) package. It exhibits an impedance of 40 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 600 mA and maintains a maximum DC resistance of 100 mOhms. It operates within a temperature range of -55°C to +125°C and measures 1.6 mm in length, 0.8 mm in width, and 0.8 mm in height.

Feature Summary

• Provides signal line filtering through high-impedance characteristics at specific frequencies
• Constructed in a compact 0603 surface-mount footprint for space-constrained designs
• Capable of handling continuous DC currents up to 600 mA without saturation

Applications

• Signal line noise suppression
• High-frequency circuit filtering
• General-purpose EMI suppression in consumer electronics

Procurement Notes

Verify the complete part number against official TDK documentation to ensure correct suffix identification. Confirm that the specific variant matches the required impedance and current ratings for the target application. Cross-reference datasheet specifications regarding package dimensions and thermal operating limits before finalizing procurement orders.

Selection Notes

Select this component when a low-profile 0603 ferrite bead is required for signal integrity management. Ensure the design accommodates the 600 mA current rating and the 100 mOhm DC resistance to prevent excessive voltage drop. Verify compatibility with standard surface-mount assembly processes and check if automotive qualification is necessary, as this specific suffix denotes commercial grade rather than AEC-Q200 certified variants.

Part Context

This component belongs to the TDK MMZ series of ferrite beads, which are widely used for electromagnetic interference suppression. The MMZ series offers various impedance values and current ratings in standardized packages. This specific model represents a mid-range impedance option suitable for general digital signal lines where moderate noise attenuation is sufficient.
