KMZ1608DHR121CTDH5

Chip Ferrite Bead Overview

The TDK KMZ1608DHR121CTDH5 is a ferrite chip bead from the KMZ-HR series, designed for signal line applications. It features a 0603 (1608 metric) surface mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.6 mm height. The component provides an impedance of 120 Ohms at 100 MHz with a tolerance of 25%. It supports a maximum DC current of 400 mA and has a maximum DC resistance of 300 mOhms. Qualified under AEC-Q200 standards, it operates within a temperature range of -55°C to +150°C.

Chip Ferrite Bead Feature Summary

• AEC-Q200 qualified for automotive reliability requirements
• Soft termination construction to enhance mechanical robustness
• Compact 0603 footprint suitable for space-constrained designs

Chip Ferrite Bead Applications

• Automotive electronic circuits requiring EMI suppression
• Signal line noise filtering in compact devices
• High-reliability consumer electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix DH5 against official TDK documentation to confirm soft termination and packaging details. Ensure the selected variant matches the required 400 mA current rating and 120 Ohm impedance specifications for the target application environment.

Chip Ferrite Bead Selection Notes

Select this component when automotive qualification and mechanical shock resistance are critical. The soft termination feature mitigates stress during PCB bending or thermal cycling. Confirm that the 0603 size fits the layout constraints and that the 400 mA rating exceeds the circuit's peak current demands.

Chip Ferrite Bead Part Context

This part belongs to the KMZ-HR series of high-robustness ferrite beads manufactured by TDK Corporation. The series is specifically engineered for automotive and demanding industrial applications where standard components might fail due to mechanical stress or extreme temperature variations.

Chip Ferrite Bead Replacement Considerations

Check for direct substitutes within the KMZ-HR series with matching impedance and current ratings. Verify that any alternative maintains AEC-Q200 qualification and soft termination characteristics if mechanical durability is required.
