MMZ1005A102ETD25

Overview

The MMZ1005A102ETD25 is a ferrite chip bead from the MMZ-E Auto series, manufactured by TDK. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 1 kOhms at a test frequency of 100 MHz and supports a maximum DC current of 250 mA. It has a maximum DC resistance of 1.2 Ohms and a tolerance of 25%. Designed for high-speed signal lines, it operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification for automotive applications.

Feature Summary

• Certified to AEC-Q200 standards for automotive reliability
• Optimized for high-speed signal line noise suppression
• Compact 0402 surface-mount form factor

Applications

• Automotive electronic circuits requiring EMI suppression
• High-speed digital signal line filtering
• Noise reduction in compact mobile devices

Procurement Notes

Verify the specific suffix TD25 against official TDK documentation to confirm packaging details such as reel size or tape specifications. Ensure the AEC-Q200 qualification status aligns with your project's automotive grade requirements. Cross-reference the impedance value at 100 MHz with circuit simulation models to validate performance in your specific application environment before finalizing procurement.

Selection Notes

Select this component when space constraints require a 0402 footprint for ferrite beads. It is suitable for applications needing 1 kOhms attenuation at 100 MHz with a 250 mA current rating. Consider the 1.2 Ohm DC resistance impact on signal integrity. Verify that the -55°C to +125°C operating range meets environmental conditions. Confirm compatibility with standard SMT reflow processes.

Part Context

This part belongs to the MMZ-E Auto series, which is specifically engineered for automotive electronics. The MMZ series generally covers various impedance and current ratings in standard packages. The 'A' in the model number typically denotes the impedance code, while 'TD25' indicates the specific packaging configuration provided by TDK for distribution channels.

Replacement Considerations

Check for other MMZ1005 variants with similar impedance and current ratings if exact substitution is needed. Verify pin compatibility and thermal characteristics. Ensure any replacement also meets AEC-Q200 if used in automotive contexts.
