MMZ1005S800AT000

Overview

The TDK MMZ1005S800AT000 is a ferrite chip bead designed for signal line noise suppression. It features an impedance of 80 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 500 mA and has a maximum DC resistance of 120 mOhms. It operates within a temperature range of -55°C to +125°C. The device utilizes a 0402 (1005 metric) surface mount package measuring 1 mm in length, 0.5 mm in width, and 0.5 mm in height. It is qualified under the AEC-Q200 standard for automotive applications.

Feature Summary

• Provides effective high-frequency noise attenuation on signal lines through ferrite material properties.
• Complies with AEC-Q200 qualification standards suitable for automotive electronic environments.
• Utilizes a compact 0402 surface-mount footprint for efficient PCB space utilization.

Applications

• Automotive signal line noise suppression
• High-speed digital circuit filtering
• General-purpose EMI suppression in consumer electronics

Procurement Notes

Verify the specific suffix 'A' against official TDK documentation to confirm its exact impact on specifications or packaging. Ensure that the selected variant matches the required AEC-Q200 automotive qualification if used in vehicle systems. Cross-reference the impedance value and current rating with the target application's electrical requirements before finalizing procurement decisions.

Selection Notes

Select this component when a low-impedance path is required for signal integrity while maintaining noise filtering capabilities. The 500 mA current rating suits moderate signal loads. Consider the 0402 package size constraints during layout design. Validate thermal performance within the specified operating temperature range to ensure reliability under varying environmental conditions.

Part Context

This part belongs to the TDK MMZ Auto series, which focuses on components meeting automotive reliability standards. The MMZ series generally offers a wide range of ferrite beads optimized for various frequency bands and current levels. This specific model targets applications requiring robust noise suppression in compact automotive and industrial form factors.

Replacement Considerations

Check for direct substitutes within the MMZ1005S800CTD25 or MMZ1005S800HT000 families if availability differs. Verify that alternative parts maintain identical impedance, current handling, and package dimensions to ensure mechanical and electrical compatibility without redesigning the circuit board.
