MMZ1005S800CTD25

Overview

The TDK MMZ1005S800CTD25 is a single-line ferrite chip bead designed for signal line noise suppression in automotive applications. It features an impedance of 80 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 500 mA. The component has a maximum DC resistance of 120 mOhms with a 25% impedance tolerance. Packaged in a compact 0402 (1005 metric) SMD footprint measuring 1 mm x 0.5 mm x 0.5 mm, it operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Optimized for high-frequency signal line noise suppression
• Compact 0402 surface-mount package design

Applications

• Automotive electronic circuit noise filtering
• Signal line interference suppression
• High-frequency data bus protection

Procurement Notes

Verify the specific suffix D25 against official TDK documentation to confirm packaging configuration and reel specifications. Ensure the procurement order matches the exact part number to avoid discrepancies in tape-and-reel quantities or handling requirements. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance status and recommended soldering profiles prior to finalizing purchase orders.

Selection Notes

Select this component when designing circuits requiring 80 Ohms of impedance at 100 MHz for signal integrity management. The 500 mA current rating suits moderate power signal lines, while the low 120 mOhm DCR minimizes voltage drop. The AEC-Q200 certification is essential for automotive subsystems, and the 0402 size fits space-constrained PCB layouts operating between -55°C and +125°C.

Part Context

This ferrite bead belongs to the TDK MMZ Auto series, specifically engineered for automotive electronics. The MMZ1005S800CTD25 utilizes manganese-zinc ferrite material to provide effective broadband noise absorption. Its construction supports automated surface-mount assembly processes, ensuring consistent performance in mass-produced automotive control units and infotainment systems.

Replacement Considerations

Consult TDK's official cross-reference tools for verified substitutes. Equivalent components must match the 0402 footprint, 80 Ohms @ 100 MHz impedance, 500 mA current rating, and AEC-Q200 qualification to ensure mechanical and electrical compatibility without redesign.
