MFBW1V1005-201-R

Overview

The MFBW1V1005-201-R is a multilayer ferrite bead from the Eaton MFBW1V1005 series, designed for EMI suppression in surface-mount applications. It features a 0402 (1005 metric) package with dimensions of 1.00mm x 0.50mm and a maximum height of 0.65mm. The component provides an impedance of 200 Ohms at 100 MHz with a tolerance of ±25%. It supports a rated current of 300mA and has a maximum DC resistance of 500 milliohms. Operating temperature ranges from -40°C to 85°C.

Feature Summary

• Multilayer chip construction for effective electromagnetic interference suppression
• Compact 0402 surface-mount footprint suitable for high-density PCB layouts
• Single-line configuration for simple circuit integration

Applications

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

Procurement Notes

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

Selection Notes

Select this component when a low-profile ferrite bead is needed for high-frequency noise reduction. The 200 Ohm impedance at 100 MHz targets common RF interference frequencies. The 300mA current rating suits low-power signal lines or small peripheral circuits. Consider the 500 milliohm DCR impact on voltage drop if used in power paths.

Part Context

This part belongs to the Eaton MFBW1V1005 series of multilayer ferrite beads. The series offers various impedance values within the same 0402 package form factor. Similar parts include MFBW1V1005-101-R and MFBW1V1005-301-R, which share the same physical dimensions but differ in impedance characteristics.

Replacement Considerations

Direct substitutes include other 0402 ferrite beads with 200 Ohms @ 100MHz impedance and ≥300mA current rating. Verify pin compatibility and thermal performance. Cross-reference with MFBM1V1005-201-R if higher current capability is acceptable.
