MMZ1608R471ATD25

Overview

The MMZ1608R471ATD25 is a single-line ferrite chip bead from the TDK MMZ Auto 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 0.95 mm maximum height. The component provides an impedance of 470 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 500 mA and has a maximum DC resistance of 300 mOhms. Operating temperatures range from -55°C to +125°C, and it holds AEC-Q200 qualification.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Single-line signal line filtering configuration
• Compact 0603 surface-mount footprint

Applications

• Automotive electronic circuit noise suppression
• Signal line EMI filtering in vehicle systems
• High-frequency interference reduction in compact automotive modules

Procurement Notes

Verify the specific suffix TD25 against official TDK documentation to confirm packaging details such as reel size or tape specifications. Ensure the order matches the exact part number to avoid confusion with similar impedance values within the MMZ1608 series. Confirm RoHS compliance status through the manufacturer's latest environmental declarations before finalizing procurement.

Selection Notes

Select this component when designing for automotive environments requiring AEC-Q200 certification. The 500 mA current rating suits moderate signal lines, while the 470 Ohm impedance targets specific high-frequency noise profiles. Verify that the 0603 package fits the PCB layout constraints and that the operating temperature range covers the intended application environment.

Part Context

This component belongs to the TDK MMZ Auto series, which specializes in ferrite beads for automotive electronics. The MMZ1608 designation indicates the 0603 case size. The 'R' in the model number typically denotes the specific material characteristic or impedance curve variant within the series, distinguishing it from other MMZ1608 variants like the S or Q series.

Replacement Considerations

Direct substitutes include other MMZ1608 series parts with identical 470 Ohm impedance and 500 mA ratings, such as MMZ1608S471ATD25 if package compatibility allows. Cross-reference with other manufacturers' 0603 ferrite beads only if electrical parameters and automotive qualification requirements are strictly matched.
