MFBW1V1005-221-R

Overview

The MFBW1V1005-221-R is a multilayer chip ferrite bead manufactured by Eaton Electronics Division. It features an impedance of 220 Ohms at 100 MHz and a maximum DC resistance of 400 milliohms. The component supports a rated current of 300 mA and operates within a temperature range of -55°C to +125°C. Housed in a compact 0402 (1005 Metric) surface-mount package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height, it provides effective high-frequency noise suppression for portable electronic circuits.

Feature Summary

• Multilayer ceramic construction for reliable high-frequency signal filtering
• Compact 0402 footprint designed for space-constrained printed circuit board layouts
• Low DC resistance characteristic to minimize power loss in signal lines

Applications

• High-speed data line noise suppression in mobile devices
• Power supply filtering for portable consumer electronics
• Signal integrity protection in compact communication modules

Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging when ordering. Confirm that the 300mA current rating aligns with your circuit's peak operational requirements. Ensure the 0402 package size fits your PCB land pattern design. Check RoHS compliance status if required by your manufacturing standards. Validate the 220 Ohm impedance value matches your target frequency spectrum for effective EMI reduction.

Selection Notes

Select this component when a low-profile solution is required for high-frequency noise attenuation. The 0402 size offers a balance between performance and board real estate efficiency. Consider the 300mA current limit to prevent saturation in low-power applications. The 400 milliohm DC resistance ensures minimal voltage drop across the filtered line. This part is suitable for general-purpose EMI suppression where space is limited.
