MFBA3V1608K-471-R

Overview

The MFBA3V1608K-471-R is an automotive-grade multilayer chip ferrite bead manufactured by Eaton Electronics. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 470 Ohms at 100 MHz and supports a maximum current rating of 0.35 A. It operates within a temperature range of -55°C to +150°C and has a maximum DC resistance of 400 mOhms.

Feature Summary

• Automotive high impedance multilayer construction designed for reliability in vehicle electronics
• Compact 0603 surface-mount footprint suitable for space-constrained PCB layouts
• High thermal stability allowing operation in extreme ambient temperatures

Applications

• High-frequency EMI suppression in automotive circuits
• Signal line filtering in vehicle electronic control units
• Power rail noise attenuation in automotive infotainment systems

Procurement Notes

Verify the complete part number including the suffix to ensure correct impedance and current ratings. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for specific automotive qualification certifications required by your application standards. Ensure storage conditions align with manufacturer guidelines to maintain component integrity before soldering.

Selection Notes

Select this component when high impedance at 100 MHz is required for EMI filtering in automotive environments. Consider the 0.35 A current limit and 400 mOhm DC resistance for power handling requirements. The wide operating temperature range makes it suitable for under-hood or exterior applications where thermal stress is significant compared to commercial grade parts.

Part Context

This ferrite bead belongs to the MFBA3 series from Eaton Electronics, specifically engineered for automotive applications. The series utilizes multilayer technology to provide consistent performance in compact packages. It is distinct from wirewound inductors like the WCLA series, offering different impedance characteristics and physical construction methods tailored for high-frequency noise suppression.
