KMZ1608YHR601BTD25

Chip Ferrite Bead Overview

The KMZ1608YHR601BTD25 is a single-line ferrite bead chip manufactured by TDK Corporation, designed for signal line applications. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.60mm length and 0.80mm width. The component provides an impedance of 600 ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 500 mA and has a maximum DC resistance (DCR) of 400 milliohms. The device operates within a temperature range of -55°C to +150°C and holds AEC-Q200 qualification.

Chip Ferrite Bead Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• High-temperature operation up to 150°C
• Flexible soft terminals for improved solder joint durability

Chip Ferrite Bead Applications

• Automotive electronic circuit noise suppression
• Signal line filtering in high-temperature environments
• EMI suppression in compact surface-mount designs

Chip Ferrite Bead Procurement Notes

Verify the specific suffix BTD25 against official TDK documentation to confirm packaging configuration and terminal specifications. Ensure compatibility with automated placement equipment regarding the 0603 footprint. Confirm that the 500mA current rating meets the thermal requirements of the target application under worst-case operating conditions.

Chip Ferrite Bead Selection Notes

Select this component when high impedance at 100 MHz is required for signal integrity in automotive or industrial settings. The 0603 size offers space efficiency compared to larger packages. Consider the 400mOhm DCR impact on signal attenuation. The extended temperature range makes it suitable for harsh environments where standard commercial parts may fail.

Chip Ferrite Bead Part Context

This part belongs to the KMZ-HR series of ferrite beads from TDK. The series is characterized by high reliability and suitability for automotive electronics. It shares the 0603 form factor with other variants but differs in impedance and current ratings. The HR designation typically indicates high-temperature performance capabilities.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other TDK KMZ-HR series parts with similar impedance and current ratings, such as KMZ1608YHR600BTD25, provided the impedance difference is acceptable for the specific circuit design.
