MFBW1V1005-750-R

Overview

The Eaton MFBW1V1005-750-R is a multilayer ferrite chip bead designed for electromagnetic interference (EMI) suppression in surface-mount applications. It features a 0402 (1005 metric) package with dimensions of 1.00mm length, 0.50mm width, and a maximum height of 0.65mm. The component provides an impedance of 75 Ohms at a test frequency of 100 MHz, with a tolerance of ±25%. It supports a maximum DC current of 450 mA and has a maximum DC resistance of 200 mOhms. The device operates within a temperature range of -40°C to +85°C and is RoHS compliant.

Feature Summary

• Multilayer construction for effective EMI noise attenuation
• Compact 0402 footprint suitable for space-constrained designs
• Shielded configuration to minimize external magnetic field interaction

Applications

• High-speed data line filtering
• Power supply output decoupling
• Clock signal noise suppression

Procurement Notes

Verify the specific impedance value and current rating against the target circuit requirements before integration. Confirm that the 0402 package dimensions align with the PCB land pattern design. Ensure the operating temperature range meets the environmental conditions of the final assembly. Check for RoHS compliance documentation if required by regulatory standards.

Selection Notes

Select this component when a low-profile ferrite bead is needed for high-frequency noise reduction. The 75 Ohm impedance at 100 MHz targets common EMI frequencies. The 450 mA current rating suits moderate power lines. Consider the 200 mOhm DCR impact on voltage drop. The shielded type offers better performance in dense layouts compared to unshielded variants.

Part Context

This part belongs to the MFBW1V series of multilayer ferrite beads from Eaton Electronics Division. The series offers various impedance values in the standard 0402 package. These components are engineered for general-purpose EMI suppression in consumer electronics and industrial equipment. The MFBW1V1005-750-R specifically provides a mid-range impedance value for balanced filtering performance.

Replacement Considerations

Compatible substitutes include other 0402 ferrite beads with similar 75 Ohm @ 100 MHz specifications and 450 mA current ratings. Verify pin compatibility and thermal characteristics before substitution.
