MFBA3V1005K-102-R

Chip Ferrite Bead Overview

The MFBA3V1005K-102-R is a single-line multilayer chip ferrite bead manufactured by Eaton Electronics Division. It features an impedance of 1 kOhm at 100 MHz and supports a maximum current rating of 200 mA. The component has a maximum DC resistance of 1.2 Ohms and operates within a temperature range of -55°C to +150°C. It utilizes a 0402 (1005 Metric) surface mount package with dimensions of 1.00mm x 0.50mm x 0.60mm. The device is AEC-Q200 qualified for automotive applications.

Chip Ferrite Bead Feature Summary

• Automotive-grade multilayer construction designed for high-frequency noise suppression
• AEC-Q200 qualification ensuring reliability in demanding environments
• Compact 0402 footprint suitable for space-constrained PCB layouts

Chip Ferrite Bead Applications

• High-frequency EMI filtering in automotive electronic systems
• Noise suppression on power lines and signal traces
• Protection of sensitive components in compact mobile devices

Chip Ferrite Bead Procurement Notes

Verify the specific part number against official Eaton documentation to confirm impedance values and tolerance ratings. Ensure compatibility with your assembly process regarding moisture sensitivity level and reflow soldering profiles. Confirm that the selected packaging format meets your production requirements without relying on distributor-specific claims.

Chip Ferrite Bead Selection Notes

Select this component when a 1 kOhm impedance at 100 MHz is required for effective high-frequency attenuation. The 200 mA current rating limits its use to low-power circuits; verify that the operating current remains below this threshold to prevent saturation. The wide temperature range makes it suitable for harsh automotive or industrial environments where thermal stability is critical.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the MFBA3V1005 series, which consists of automotive multilayer chip ferrite beads. The series is characterized by its small 0402 package size and robust construction designed to meet automotive quality standards. It serves as a passive component for electromagnetic interference suppression in modern electronic assemblies.

Chip Ferrite Bead Replacement Considerations

Consult Eaton's official cross-reference guides for verified substitutes. Ensure any replacement maintains the same 1 kOhm impedance at 100 MHz, 200 mA current rating, and 0402 package dimensions to preserve circuit performance and mechanical fit.
