MFBW1V1005-110-R

Overview

The Eaton MFBW1V1005-110-R is a multilayer ferrite chip bead designed for electromagnetic interference (EMI) suppression in surface-mount applications. It features an impedance of 11 Ohms at a test frequency of 100 MHz, with a tolerance range of 7 to 15 Ohms. The component supports a maximum DC current of 800 mA and exhibits a maximum DC resistance of 40 mOhms. Housed in a compact 0402 (1005 metric) package measuring 1.0 mm x 0.5 mm x 0.5 mm, it operates within a temperature range of -40°C to +85°C.

Feature Summary

• Multilayer construction provides effective EMI noise attenuation in high-density circuit layouts.
• Shielded design minimizes magnetic field leakage and crosstalk between adjacent components.
• High current handling capability allows integration into power supply lines without saturation.

Applications

• Power supply filtering in portable electronic devices
• Signal line protection in consumer electronics
• Noise suppression in automotive infotainment systems

Procurement Notes

Verify the specific suffix 'R' corresponds to the required packaging format, such as cut tape or reel, as this affects handling compatibility. Confirm RoHS compliance status through official documentation before integration. Ensure the supplier provides traceability data matching the Eaton Electronics manufacturing records to guarantee component authenticity and performance consistency.

Selection Notes

Select this component when a low-profile 0402 footprint is required for space-constrained designs. The 11 Ohm impedance value targets specific noise frequencies around 100 MHz. Evaluate the 800 mA current rating against peak load requirements to prevent thermal degradation. Compare DCR specifications against voltage drop constraints in the target circuit path.

Part Context

This part belongs to the MFBW1V series of multilayer ferrite beads from Eaton Electronics. The series offers various impedance values within the same 0402 mechanical envelope, allowing designers to standardize assembly processes while adjusting filtering characteristics. The MFBW1V1005-110-R specifically addresses mid-range noise suppression needs in compact form factors.

Replacement Considerations

Cross-reference with other 0402 ferrite beads offering 11 Ohms @ 100 MHz and >800 mA ratings. Verify equivalent impedance tolerances and DC resistance limits to ensure circuit performance parity. Check physical dimension compatibility for existing footprints.
