MMZ1608R300ATD25

Overview

The MMZ1608R300ATD25 is a surface-mount ferrite chip bead from the TDK MMZ series, designed for signal line applications. It features a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 30 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 1.5 A. It has a maximum DC resistance of 50 mOhms and a tolerance of ±25%. Operating within a temperature range of -55°C to +125°C, it meets AEC-Q200 automotive qualification standards.

Feature Summary

• AEC-Q200 qualified for automotive reliability requirements
• Optimized for high-current signal line noise suppression
• Compact 0603 surface-mount footprint

Applications

• Automotive electronic circuits
• Signal line noise filtering
• High-current data transmission paths

Procurement Notes

Verify the specific suffix TD25 against official TDK documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the procurement order explicitly references the full part number to distinguish this variant from other MMZ series configurations. Cross-reference the AEC-Q200 certification status with the manufacturer's latest quality declarations prior to finalizing supply agreements.

Selection Notes

Select this component when designing circuits requiring significant current handling capability alongside moderate high-frequency attenuation. The 1.5 A rating makes it suitable for power-sensitive signal lines where lower-current beads would fail. Verify that the 30 Ohm impedance profile aligns with the target noise spectrum at 100 MHz. Confirm that the 0603 package size fits the available PCB real estate constraints.

Part Context

This component belongs to the TDK MMZ Auto series, which focuses on robust ferrite solutions for automotive environments. The MMZ1608R300ATD25 specifically addresses the need for durable noise suppression in high-current scenarios. It complements lower-current variants in the same family by offering enhanced thermal and electrical stability under heavy load conditions typical in modern vehicle electronics.

Replacement Considerations

Consult TDK datasheets for direct substitutes within the MMZ1608 series sharing identical 30 Ohm impedance and 1.5 A current ratings. Verify pin compatibility and physical dimensions before substituting with components from other manufacturers.
