MMZ1608D121CTDH5

Overview

The TDK MMZ1608D121CTDH5 is a single-line ferrite chip bead designed for signal line applications. It features an impedance of 120 Ohms at 100 MHz with a maximum DC resistance of 300 milliohms and a rated current of 400 mA. The component utilizes a 0603 (1608 metric) surface-mount package measuring 1.6 mm in length and 0.8 mm in width. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 automotive qualification.

Feature Summary

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

Applications

• Automotive electronic circuit protection
• Signal line noise suppression
• EMI/RFI filtering in compact devices

Procurement Notes

Verify the specific suffix DH5 against official TDK documentation to confirm the exact rating parameters, as series variations exist. Ensure the procurement source provides valid RoHS compliance data and confirms the component meets the specified AEC-Q200 automotive grade requirements before integration into production.

Selection Notes

Select this component when a 120 Ohm impedance at 100 MHz is required for signal lines with a maximum current draw of 400 mA. The 0603 package size suits space-constrained designs. Verify that the 300 milliohm DC resistance aligns with the power loss constraints of the target circuit application.

Part Context

This part belongs to the TDK MMZ Auto series, which consists of ferrite beads specifically engineered for automotive electronics. The series emphasizes high reliability and stability under varying thermal conditions, adhering to strict automotive industry standards for electromagnetic interference suppression.

Replacement Considerations

The MMZ1608B121CTAH0 offers similar 120 Ohm impedance but supports 600 mA current with lower DC resistance. Verify if the higher current capacity or different physical dimensions are acceptable for the design.
