MFBA3V1005K-601-R

Chip Ferrite Bead Overview

The Eaton MFBA3V1005K-601-R is a single-line multilayer chip ferrite bead designed for surface mount applications. It features a 0402 (1005 Metric) package with dimensions of 1.00mm x 0.50mm x 0.60mm. The component provides an impedance of 600 Ohms at 100 MHz and has a maximum DC resistance of 800 mOhms. It supports a current rating of 200mA and operates within a temperature range of -55°C to 150°C. This part is AEC-Q200 qualified for automotive use.

Chip Ferrite Bead Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Multilayer chip construction in a compact 0402 footprint
• High operating temperature capability up to 150°C

Chip Ferrite Bead Applications

• Automotive electronic circuit noise suppression
• High-frequency signal line filtering
• Power supply rail decoupling in compact modules

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'K' against the official Eaton datasheet to confirm if it denotes a specific tape/reel quantity or marking variation, as distributor listings may not explicitly define this character's functional impact. Ensure the selected packaging format (Tape & Reel, Cut Tape, or Digi-Reel) matches the assembly equipment requirements. Confirm the AEC-Q200 certification status directly from the manufacturer documentation prior to procurement for automotive projects.

Chip Ferrite Bead Selection Notes

Select this component when a 0402 footprint is required for space-constrained designs needing 600 Ohms attenuation at 100 MHz. The 200mA current rating limits its use in high-power lines; compare with higher-current alternatives like the MFBM1V series if load currents exceed this threshold. The extended -55°C to 150°C temperature range makes it suitable for harsh automotive environments compared to standard commercial grade parts.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the MFBA3V1005 series from Eaton Electronics Division. It is part of a family of automotive-grade multilayer chip beads designed for electromagnetic interference suppression. The series offers various impedance values within the same 0402 package size to allow for design flexibility while maintaining consistent mechanical and thermal characteristics across the product line.

Chip Ferrite Bead Replacement Considerations

The MFBM1V1005-601-R is a similar 600 Ohm 0402 ferrite bead but differs in current rating (500mA vs 200mA) and temperature range (-40°C to 85°C). Verify that the lower temperature rating and different electrical characteristics of the MFBM1V series are acceptable for the specific application environment before substitution.
