KMZ1608BHR102CTD25

Chip Ferrite Bead Overview

The TDK KMZ1608BHR102CTD25 is a surface-mount ferrite bead designed for signal line noise suppression. It features a 1 kOhm impedance at 100 MHz with a maximum DC resistance of 600 mOhms and a current rating of 300 mA. The component operates within a temperature range of -55°C to +150°C and meets AEC-Q200 automotive qualification standards. Its physical dimensions are 1.6 mm in length, 0.8 mm in width, and 0.8 mm in height, utilizing a flexible soft termination package.

Chip Ferrite Bead Feature Summary

• Soft termination design reduces mechanical stress on the PCB during thermal cycling or board flexing.
• Automotive-grade construction compliant with AEC-Q200 reliability standards.
• High-temperature capability supports operation up to 150°C.

Chip Ferrite Bead Applications

• Noise suppression in automotive electronic control units (ECUs)
• Signal line filtering in automotive multimedia systems
• General high-temperature circuit protection

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'C' against official TDK documentation to confirm the exact impedance tolerance and termination characteristics, as distributor listings may vary. Ensure the selected variant matches the required 300 mA current rating and 600 mOhm DC resistance for the target application. Cross-reference the AEC-Q200 certification status directly with the manufacturer's datasheet to guarantee compliance with automotive quality requirements.

Chip Ferrite Bead Selection Notes

Select this component when signal integrity requires noise attenuation at 1 kOhm while maintaining low insertion loss via minimal DC resistance. The soft termination feature is critical for applications subject to mechanical vibration or thermal expansion mismatch. Verify that the 300 mA current handling capacity exceeds the peak operating current of the protected signal line to prevent saturation or overheating.

Chip Ferrite Bead Part Context

This part belongs to the KMZ-HR series of automotive ferrite beads from TDK. The series is characterized by its high-temperature stability and robust mechanical design suitable for demanding environments. The 1608 metric footprint allows for compact PCB layouts while providing sufficient thermal mass for heat dissipation under continuous load conditions.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include MMZ1608Y102BTD25 and MMZ1608R102ATD25, which share similar electrical parameters but differ in termination type. Alternative KMZ variants such as KMZ1608AHR252BTD25 offer different impedance levels. Verify mechanical compatibility and current ratings before substitution.
