MDF2016BSS420CTD25

Chip Ferrite Bead Overview

The MDF2016BSS420CTD25 is a ferrite bead chip manufactured by TDK Corporation, designed for noise suppression in power lines. It features a 0806 (2016 Metric) surface mount package with dimensions of 2.00mm length and 1.60mm width. The component provides an impedance of 42 Ohms at 2 MHz and supports a rated current of 850mA. Its maximum DC resistance is 300mΩ, and it operates within a temperature range of -40°C to 125°C. This part is AEC-Q200 qualified for automotive applications.

Chip Ferrite Bead Feature Summary

• Provides effective radiation noise suppression for power line circuits
• Qualified for automotive reliability standards via AEC-Q200 certification
• Designed for surface mount assembly in compact electronic layouts

Chip Ferrite Bead Applications

• Automotive electronics systems
• Power line noise filtering
• Radiation noise suppression in embedded devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix TD25 against official TDK documentation to confirm packaging details. Ensure the selected variant matches the required impedance and current ratings for the target power line application. Cross-reference the AEC-Q200 qualification status if automotive compliance is mandatory for the design.

Chip Ferrite Bead Selection Notes

Select this component when a low-impedance path is required for power lines with moderate current demands up to 850mA. The 0806 package offers a balance between current handling capability and board space efficiency. Consider the 42 Ohm impedance at 2 MHz to ensure adequate attenuation for the specific noise frequencies present in the circuit.

Chip Ferrite Bead Part Context

This component belongs to the MDF series of ferrite beads from TDK, which are specialized for power line applications. Unlike signal line beads, these are optimized for higher current handling while maintaining noise suppression capabilities. The series is widely used in automotive and industrial sectors where robust EMI/RFI filtering is critical for system stability.

Chip Ferrite Bead Replacement Considerations

Consult TDK's official substitution guide for equivalent parts within the MDF or MMZ series. Verify that any alternative maintains the same 0806 footprint, 850mA rating, and 42 Ohm @ 2 MHz impedance characteristics to ensure circuit compatibility.
