MFBW1V1005-181-R

Overview

The Eaton MFBW1V1005-181-R is a multilayer ferrite chip bead designed for electromagnetic interference 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 180 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 450 mA and has a maximum DC resistance of 0.40 Ohms. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Multilayer construction for effective EMI suppression
• Compact 0402 surface-mount footprint
• High current handling capability relative to package size

Applications

• Portable electronic devices requiring compact filtering
• Data line protection in consumer electronics
• Power supply output filtering for low-voltage circuits

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official Eaton datasheet prior to integration. Confirm that the 0402 package dimensions align with the target PCB land pattern. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Selection Notes

Select this component when space constraints necessitate a 0402 ferrite bead with moderate current capacity. The 180 Ohm impedance at 100 MHz suits general noise suppression rather than high-frequency RF filtering. Evaluate the 450 mA current rating against the circuit's peak load to prevent saturation. Consider the 0.40 Ohm DC resistance impact on voltage drop in sensitive power rails.

Part Context

This part belongs to the Eaton MFBW1V series of multilayer ferrite beads. The series offers various impedance values within the same 0402 form factor. It is manufactured by Eaton Electronics Division, a provider of electronic components for industrial and commercial markets. The product complies with RoHS3 standards and is available in tape and reel packaging for automated assembly.

Replacement Considerations

Direct substitutes include other Eaton MFBW1V1005 variants with different impedance ratings, such as MFBW1V1005-101-R or MFBW1V1005-201-R, provided the electrical characteristics match the design requirements.
