MFBW1V1005-301-R

Overview

The MFBW1V1005-301-R is a single-line ferrite bead from the MFBW1V1005 series, manufactured by Eaton Electronics Division. Designed for surface-mount installation in the 0402 (1005 metric) package, it measures 1.00mm x 0.50mm with a maximum height of 0.65mm. The component provides an impedance of 300 Ohms at 100 MHz and supports a maximum current rating of 300mA. It features a maximum DC resistance of 500 milliohms and operates within a temperature range of -40°C to 85°C.

Feature Summary

• Provides electromagnetic interference suppression through high impedance characteristics at specific frequencies
• Utilizes a compact 0402 surface-mount footprint for efficient board space utilization
• Constructed as a multilayer chip bead for reliable EMI filtering in dense circuit layouts

Applications

• High-frequency noise suppression in portable electronic devices
• Signal integrity protection in data transmission lines
• Power line filtering in compact consumer electronics

Procurement Notes

Verify that the ordering suffix matches the required impedance tolerance and packaging format. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the supplier documentation explicitly lists the Eaton part number to avoid substitution errors with generic equivalents.

Selection Notes

Select this component when a 300 Ohm impedance at 100 MHz is required for a single-line application. The 300mA current rating dictates suitability for low-power signal paths rather than high-current power rails. The 0402 package size is appropriate for applications with strict spatial constraints where larger ferrite beads cannot fit.

Part Context

This part belongs to the MFBW1V1005 series of multilayer ferrite chip beads designed for EMI suppression. The series offers various impedance values and current ratings within the same 0402 form factor, allowing designers to standardize on a single package size while adjusting electrical performance parameters for different circuit requirements.

Replacement Considerations

Cross-reference with other Eaton MFBW1V1005 variants such as MFBW1V1005-190-R for different impedance levels. Verify pin compatibility and impedance curves before substituting with components from other manufacturers to ensure equivalent noise suppression performance.
