MFBM1V1005-190-R

Overview

The Eaton MFBM1V1005-190-R is a multilayer chip ferrite bead designed for EMI suppression in surface-mount applications. It features a 0402 (1005 metric) package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 19 Ohms at a test frequency of 100 MHz, with a tolerance range of 12 to 25 Ohms. It supports a maximum DC current of 1.5 A and has a maximum DC resistance of 60 mOhms. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Shielded design to contain magnetic fields
• Single-channel configuration for compact circuit integration

Applications

• High-speed data line filtering
• Power supply noise reduction
• General-purpose EMI suppression in portable electronics

Procurement Notes

Verify the specific impedance tolerance and current rating requirements against the official Eaton datasheet before procurement. Confirm that the 0402 package footprint matches the target PCB layout. Ensure compliance with RoHS3 standards if required by the end product specifications. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when space constraints require a 0402 footprint ferrite bead. Choose based on the 19 Ohm impedance requirement at 100 MHz and the 1.5 A current handling capability. Consider the low DC resistance of 60 mOhms for minimal signal attenuation. Verify thermal performance within the specified -40°C to +85°C operating range for the intended environment.

Part Context

This part belongs to the Eaton MFBM1V series of multilayer ferrite beads. The series is characterized by high saturation current capabilities and stable impedance characteristics over temperature. These components are engineered for use in consumer electronics, telecommunications, and computer equipment where small form factors and reliable noise suppression are critical.

Replacement Considerations

Direct substitutes include other 0402 ferrite beads with 19 Ohms impedance and similar current ratings from Eaton or compatible manufacturers. Verify pin compatibility and impedance curves to ensure equivalent EMI suppression performance. Check for any differences in mounting pad designs or thermal characteristics.
